Haworthia cymbiformis

Haworthia cymbiformis is a species of the genus "Haworthia" in the family Asphodelaceae, endemic to the Eastern Cape Province in South Africa.
Description.
Plants are small and grow clumps of rosettes of thick, fleshy, light green leaves. As one of the soft green group of "Haworthias" it is frequently confused with its relatives (e.g. "Haworthia cooperi" which shares a similar distribution range, as well as "Haworthia mucronata" and "Haworthia marumiana" to the west).
A distinctive feature is the soft, "boat-shaped" leaves ("cymbiformis" actually means "boat-shaped"). Its leaves are not recurved like the "retuse" Haworthias (e.g. "Haworthia mirabilis" or "Haworthia retusa").
Another feature is that the leaves usually have transparent streaks around their tips. In the wild, the sun is very bright, and the plant grows mostly buried by sand with only these transparent tips above the ground.
Distribution.
The natural range of this species is roughly between Port Elizabeth and East London in Eastern Cape Province, South Africa.
This range closely matches that of its relative, "Haworthia cooperi". "H.cymboformis" grows on cliffs and "H.cooperi" grows on lowland plains.
This is a summer rainfall region.
