Description: Eriosyce reconditaSN|2876]]SN|2876]] var. vexata (formerly Pyrrhocactus vexatusSN|2885]]SN|2885]]), appears to be a dwarf, weakly spined ally of Neoporteria aricensisSN|2891]]SN|2891]] (syn: Eriosyce reconditaSN|2876]]SN|2876]]), 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.
