Tunilla erectocladaSN|3724]]SN|3738]] is a low-growing ground covers miniature prickly pear. It is densely branched, prostrate and forms large clumps or mats. It only grows about 2 pads high (less than 10 cm tall), growth is mostly sideways.

Flowers
Extremely vivid orange to carmine red. Pericarpels elongate, tuberculate, bristly.
Taxonomic Notes
The species is recognized as a provisional taxon by Hunt et al. (2006). Expert R. Kiesling does not recognize it as a good species but as part of Tunilla corrugataSN|3738]]SN|3724]] and argues that T. erectoclada was described from cultivated plants and its origin is unknown and it holds the characters of T. corrugata.

4-7 white needle-like, frail, 4-10 mm long, bent backward and lying next to the surface or spreading
Fruits
Fleshy but thin walled splitting open laterally at maturity.
