Haworthia coarctata var greenii
Description
H.coarctata grows in large clumps in its natural habitat, with long stems packed with robust succulent leaves. It is normally dark green but sometimes acquires a rich purple-red when in full sunlight.
It is frequently confused with Haworthia reinwardtii, which occurs just to the east of its natural range. However H.coarctata has smaller, smoother and rounder tubercles on its leaves (those of H.reinwardtii are sometimes larger, flatter and whiter). H.coarctata also usually has much wider, fatter leaves.
Forms and varieties
This is a variable species, and several forms and varieties are recognised. Several are listed below:
- Haworthia coarctata var. adelaidensis (Poelln.) M.B.Bayer; longer narrower leaves than type

- Haworthia coarctata f. greenii (Baker) M.B.Bayer; smooth leaves with tubercles mostly absent
- Haworthia coarctata f. tenuis (G.G.Sm.) M.B.Bayer; narrow stems and thinner leaves
