Description
Rebutia neocumingii is a very variable species as to its spines and subtle differences of tone in its yellow to orange flowers.
Stem: Usually solitary, globose to short cylindrical up to 10 cm wide, 20 cm tall.
Ribs:16 to 18 tuberculate, often spiraling.
Central spines: 2 to 8 up to 2 cm long.
Radial spines: 5 to 24 yellowish with brown tips, about 1 cm long.
Flowers: Approx. 2 cm long, 2,5 cm in diameter, they are produced (unusually) all over the body of the plant especially near the very tips of the stems differing from other rebutias in that its flowers appear very near the meristem as opposed to the lower, stem side and base locations of those others. As well, on this and a few other ex Weingartia species, one areole can produce up to 4 flowers.
Blooming season: The flowers are produced in early summer and remain open for five or six days.
Origin and Habitat
Rebutia neocumingii has a relatively large range throughout the Bolivian Andes mountains where it occurs in Chuquisaca, Cochabamba, Potosí and Santa Cruz (extent of occurrence is 11,500 km2).
Altitude: It grows at elevations of 1400 to 3000 metres above sea level
Habitat and Ecology: The species is found in seasonally dry inter-Andean valleys together with Parodia comarapana and Winterocereus aureispinus. The species is abundant and its population is stable. There are no known major threats to this species.
Cultivation and Propagation
In culture it is without problems, easy to grow, very attractive and regularly shows its beautiful flowers, if provided with an adequate winter rest period.
Growth rate: It is a pretty slow grower.
Soil: Grow it in an open mineral, sandy-gritty cactus compost and provide a very good drainage.
Repotting: It is better that they are repotted regularly. Repotting will increase size of stems and the number of flowers produced. Repot yearly until reaching about 100 mm in size, then every two or three years will suffice. Repotting is best done at the end of winter but can be done at other times. Do not water for a couple of weeks after repotting to reduce risk of root rot via broken roots.
Pots: It needs a relatively shallow pot to accommodate its fibrous roots and provide a very good drainage. It may stay in the same pot for many years.
Moisture: It is sensitive to over-watering (rot prone), and needs good drainage. In the winter keep it cool, and absolutely dry conditions. In summer keep it well watered when it’s hot. They are really not very demanding and regular watering in their growing season creates healthy disease resistant plants that will flower better.
Special need: Provide very good ventilation. Nearly all problems occur as a result of overwatering and poor ventilation, especially when weather conditions are dull and cool or very humid.
Fertilization: Light fertilizer seems to boost its growth whenever additional water is given. Feed it during the growing season with a fertilizer specifically formulated for cactus and succulents (high potash fertilizer with a dilute low nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label. It thrive in poor soils and needs a limited supplies of fertilizer to avoid the plant developing excess vegetation, which is easily attacked by fungal diseases.
Exposure: Needs full sun. To achieve the best spine density give these plants lots of sun.
Hardiness: Keep dry or slightly moist in winter at a minimum temperature of 5°C (But Hardy to -4°C or less). In mild climate they grow well when planted freely outside in well-drained soil.
Pest and diseases: Occasionally these plants are infested by mites and mealy-bugs, but all known garden pests can be kept to a minimum by simply ensuring optimal growing conditions and healthy plants.
Use: It can be cultivated outdoors in raised beds and terraces. It do well in pots as well.
Propagation: Seeds. The seeds can be sown in pots of fine, well-drained sandy soil, any time during the spring when temperatures are warm. Cover the seeds with a fine layer of grit and water from below with a fungicide to prevent damping off. For the 1-2 weeks cover the pots with a sheet of glass/clear perspex to keep the humidity levels high. Remove the glass and replace it with light shade-cloth and mist once or twice a day for the next two weeks after which most seeds should have germinated. From then on mistings can be reduced to every second and then every third day as the little plants grow. The seedlings should not be disturbed until they are well rooted after which they can be planted separately in small pots.
Notes
All the 60 species of genus Weingartia have been transferred to synonymy status under the genus Rebutia; about 45 or so of them as synonyms of two species, Rebutia canigueralii and Rebutia neocumingii. The genus Weingartia was always considered difficult to differentiate from Gymnocalycium, Neowerdermanniana, and Sulcorebutia and its name has had a very eventful history which evidently continues in controversy today. Echinocactus cumingiiSalm-Dyck non Hopffer has been resolved in the Backeberg’s new name Weingartia neocumingii.

From llifle page Sulcorebutia longigibba
Description
Weingartia longigibba, is generally included within (as a synonym of) Rebutia neocumingii, suggesting that there is not really a fundamental difference between the two, and hard to name accurately without knowing where they come from. The bodies are more or less spherical 5 to 9 cm, or more in cultivation and clustering from around the base; the tubercles are large and prominant and very similar to those of Weingartia riograndensis.
The areoles are woolly like those of Weingartia lanata and the flowers are 3 are about 3 cm long and wide, golden yellow, sometimes paler yellow.
Derivation of specific name: The name longigibba, meaning “long humpy”, refers to the large tubercles that helps distinguish this cactus from the other related taxon.
Stem: At fist solitary often clustering from around the base with age, globose to short cylindrical , light green, with a spiny crown, not depressed, 5 to 9 cm, or more in cultivation, later becoming 2 or 3 times as tall as broad.
Ribs: 16-18 tuberculate, often spiraling. Tubercles large and prominent 25-40 mm long, 15-25 mm wide, and 10 to over 15 mm high, steep, lacking a chin below the areole.
Areoles: 8 to 12 mm long, 3 to 6 mm wide, with pale brownish wool, more developed in the younger, upper part of the stem, the areole groove continues downwards as a dividing furrow between the tubercles.
Central spines: 3-8, longer and stronger than the radials (15-35 mm long) pale greyish brown, with slightly darker brown tips.
Radial spines: 7-12, similarly coloured, 10-25 mm long, the upper the longer, straight or a little curved.
Flowers: Approx 3 cm long and wide in diameter golden yellow, or paler yellow, the tepals often darker-tipped. The flowers are produced near the crown of the plant especially near the very tips of the stem or at the shoulder of the stem.
Fruit: Longish, pale green, about 10 mm long and 6 mm wide.
Blooming season: The flowers are produced in early summer and remain open for five or six days.
Origin and Habitat
Bolivia, Department Chuquisaca, Province of Oropeza.
Altitude range: 1900-2600 metres above sea level.
Habitat: Weingartia longigibba grow on sandstone rocks near the Rio Chico.

Description
Rebutia neocumingii f. prolifera| is a monstrous highly branching plant that forms large clumps and blooms abundantly, just as a small specimen.
Stem: Globose to short cylindrical up to 10 cm wide, 20 cm tall, branching freely from the base and forming large crowded mounds.
Ribs: 16 to 18 tuberculate, often spiraling.
Central spines: 2 to 8 up to 2 cm long.
Radial spines: 5 to 24 yellowish with brown tips, about 1 cm long.
Flowers: Approx. 2cm. long, 2,5 cm in diameter, they are produced (unusually) all over the body of the plant expecially near the very tips of the stems differing from other rebutias in that its flowers appear very near the meristem as opposed to the lower, stemside and base locations of those others. As well, on this and a few other ex Weingartia species, one areole can produce up to 4 flowers.
Blooming season: The flowers are produced in early summer and remain open for five or six days.
Origin and Habitat
Garden origin (Nursery produced cultivar)
Cultivation and Propagation
In culture it is without problems, easy to grow, very attractive and regularly shows its beautiful flowers, if provided with an adequate winter rest period.
Growth rate: It is a pretty slow grower, but easily flowering species. It offset from the base and can fill a 25 cm pot in just a few years given the best conditions.
Soil: Grow it in an open mineral, sandy-gritty cactus compost and provide a very good drainage.
Repotting: It is better that they are repotted regularly. Repotting will increase size of stems and the number of flowers produced. Repot yearly until reaching about 100 mm in size, then every two or three years will suffice. Repotting is best done at the end of winter but can be done at other times. Do not water for a couple of weeks after repotting to reduce risk of root rot via broken roots.
Pots: It needs a relatively shallow pot to accommodate its fibrous roots and provide a very good drainage. It may stay in the same pot for many years.
Moisture: It is sensitive to over-watering (rot prone), and needs good drainage. In the winter keep it cool, and absolutely dry conditions. In summer keep it well watered when it’s hot. They are really not very demanding and regular watering in their growing season creates healthy disease resistant plants that will flower better.
Special need: Provide very good ventilation. Nearly all problems occur as a result of overwatering and poor ventilation, especially when weather conditions are dull and cool or very humid.
Fertilization: Light fertilizer seems to boost its growth whenever additional water is given. Feed it during the growing season with a fertilizer specifically formulated for cactus and succulents (high potash fertilizer with a dilute low nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label. It thrive in poor soils and needs a limited supplies of fertilizer to avoid the plant developing excess vegetation, which is easily attacked by fungal diseases.
Exposure: Needs full sun. To achieve the best spine density give these plants lots of sun.
Hardiness: Keep dry or slightly moist in winter at a minimum temperature of 5°C (But Hardy to -4°C or less). In mild climate they grow well when planted freely outside in well-drained soil.
Pest and diseases: Occasionally these plants are infested by mites and mealy-bugs, but all known garden pests can be kept to a minimum by simply ensuring optimal growing conditions and healthy plants.
Use: It can be cultivated outdoors in raised beds and terraces. It do well in pots as well.
Propagation: Seeds. The seeds can be sown in pots of fine, well-drained sandy soil, any time during the spring when temperatures are warm. Cover the seeds with a fine layer of grit and water from below with a fungicide to prevent damping off. For the 1-2 weeks cover the pots with a sheet of glass/clear perspex to keep the humidity levels high. Remove the glass and replace it with light shade-cloth and mist once or twice a day for the next two weeks after which most seeds should have germinated. From then on mistings can be reduced to every second and then every third day as the little plants grow. The seedlings should not be disturbed until they are well rooted after which they can be planted separately in small pots.

The flowers forms an irregular crown on the plant apex and have a hard time coming through the dense mass of spines. This cactus is indeed beautiful even without its blooms.
Derivation of specific name: Weingartia hajekyana was named in honour of the Czech cactus expert F. Hájek. This plants are often found in cultivation under many different spelling such as: hajekijána or hajekyana.
Blooming season: The flowers are produced in early summer and remain open for five or six days.
Origin and Habitat
Mairana, Bolivia
Altitude: 1300(-1500) metres above sea level.
Cultivation and Propagation
In culture Weingartia hajekyana is without problems, easy to grow, very attractive and regularly shows its beautiful flowers, if provided with an adequate winter rest period.
Growth rate: It is a pretty slow grower.
Soil: Grow it in an open mineral, sandy-gritty cactus compost and provide a very good drainage.
Repotting: It is better that they are repotted regularly. Repotting will increase size of stems and the number of flowers produced. Repot yearly until reaching about 100 mm in size, then every two or three years will suffice. Repotting is best done at the end of winter but can be done at other times. Do not water for a couple of weeks after repotting to reduce risk of root rot via broken roots.
Pots: It needs a relatively shallow pot to accommodate its fibrous roots and provide a very good drainage. It may stay in the same pot for many years.
Moisture: It is sensitive to over-watering (rot prone), and needs good drainage. In the winter keep it cool, and absolutely dry conditions. In summer keep it well watered when it’s hot. They are really not very demanding and regular watering in their growing season creates healthy disease resistant plants that will flower better.
Special need: Provide very good ventilation. Nearly all problems occur as a result of overwatering and poor ventilation, especially when weather conditions are dull and cool or very humid.
Fertilization: Light fertilizer seems to boost its growth whenever additional water is given. Feed it during the growing season with a fertilizer specifically formulated for cactus and succulents (high potash fertilizer with a dilute low nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label. It thrive in poor soils and needs a limited supplies of fertilizer to avoid the plant developing excess vegetation, which is easily attacked by fungal diseases.
Exposure: Needs full sun. To achieve the best spine density give these plants lots of sun.
Hardiness: Keep dry or slightly moist in winter at a minimum temperature of 5°C (But Hardy to -4°C or less). In mild climate they grow well when planted freely outside in well-drained soil.
Pest and diseases: Occasionally these plants are infested by mites and mealy-bugs, but all known garden pests can be kept to a minimum by simply ensuring optimal growing conditions and healthy plants.
Use: It can be cultivated outdoors in raised beds and terraces. It do well in pots as well.
Propagation: Seeds. The seeds can be sown in pots of fine, well-drained sandy soil, any time during the spring when temperatures are warm. Cover the seeds with a fine layer of grit and water from below with a fungicide to prevent damping off. For the 1-2 weeks cover the pots with a sheet of glass/clear perspex to keep the humidity levels high. Remove the glass and replace it with light shade-cloth and mist once or twice a day for the next two weeks after which most seeds should have germinated. From then on mistings can be reduced to every second and then every third day as the little plants grow. The seedlings should not be disturbed until they are well rooted after which they can be planted separately in small pots.
