Pinguicula cubensis

A tiny butterwort known only from the Sierra de Cajálbana in Pinar del Río, western Cuba. The type was collected on a waterfall near the summit of the range, which is on serpentine. It is tropical, lives in warm, humid conditions and has no cold season, so the job in cultivation is steady warmth and constantly wet rock.

Where it grows wild

Wet rock at waterfalls and seepages on the serpentine Sierra de Cajálbana. Details beyond the type locality are thin; this is inferred from the type label and related Caribbean species of section Agnata.

The measured site is at about 220 m on the low Cajálbana range, whose summit is a few hundred metres high.
