Cryptophyte, endemic to mountain ranges of Buenos Aires province. Vulnerable due to restricted habitat ( Delucchi 2006).

Characteristics. Perennial herb. Bulbs subglobose. Peduncles erect, branched, to 1 m tall. Basal leaves scarce, linear in shape, parallel-veined, folded, to 35 cm long, 2.5 cm wide. Inflorescence: a cyme (rhipidium); bracts unequal, with 1–2 flowers; tepals orange-brown, filaments free, styles entire. Fruit: a capsule.

Comments. This is a rare species in the study area. It grows in full sunlight conditions in rock cracks on slopes. It is very similar to C. herbertii ssp. herbertii , but this last species presents vivid orange tepals and united filaments.
