Eriosyce recondita var. vexata (F.Ritter) A.E.Hoffm.

Family: CACTACEAE · Variety or form of Eriosyce recondita

Publication: Cact. Fl. Silvestre Chile 212. 1989

Description

Eriosyce recondita var. vexata (formerly Pyrrhocactus vexatus), appears to be a dwarf, weakly spined ally of Neoporteria aricensis (syn: Eriosyce recondita), but not sufficiently differentiated and considered merely a local variant of the latter (if not the same) and it is hard to tell apart one from the others, if not for the geographical provenance. It is a spherical, sometimes branching cactus species barely protruding from the ground surface.

Stem: Grey to dark green about 5,5 cm across.

Root: Taproots expanded, often with necks.

Ribs: About 13, 5- 10 mm high, notched and forming tubercles and often with sunken areoles.

Spines: Thin, needle-like, yellow-brown to black, becoming grey; centrals 1-2, 1-3 cm long, upcurved; radial s 10-16, 8-15 mm long.

Flowers: Borne on young areoles, funnelform, 2 x 2 cm, scales of pericarpel and tube with dense woolly hairs and sometimes bristles, tube very short. Perianth pale yellow. Style and stigmas yellow.

Fruit: Club-shaped, elongate, hollow 1-2 (or more) cm long, 1-1.5 cm, dark red or reddish brown, dehiscing by basal pores.

Origin and Habitat

Morro Moreno, Antofagasta, Chile

Altitude range: 600-950 metres above sea level.
