Description
This is the nice crested form of the beautiful Turbinicarpus pseudopectinatus “inermis” It is a very interesting almost spineless form of the well known species recognizable without problems for the areoles with very few and extremely reduced spines, whereas the white bunches are more significant. The monstrous spine/areole pattern vaguely resembles a Pelecyphora asseliformis very much though.
Stem: Dull green apex with short white hair.
Tubercles: Compressed laterally (hatchet shaped), spirally-arranged.
Areoles: Linear about 0,5 mm wide and up to 5 mm long, with some white wool.
Spines: Absent or very short, usually less than 1 mm long a comb like formation (pectinated).
Root: Tuberose and usually bigger than the stem itself.
Flowers: Pinkish smaller than the species, petals very thin.
Blooming season: Spring.
Origin and Habitat
Garden origin (Nursery produced cultivar)
Cultivation and Propagation
This species is not very easy to cultivate. It requires full sun and careful watering to keep the plant compact and low. It has a tap root, and watering it properly is often difficult, because it tends to crack open or rot if over-watered. For this reasons it is usually found grafted on columnar cacti.
Frost tolerance: Hardy to -4°C for a short period.
Propagation: By vegetative propagation: grafting or stem cuttings.
