Haworthia Coarctata var Chalwinii

Haworthia coarctata v chalwinii is one of the morphological or geographical form of the coarctata group. It is a small plant which grows many upright leaf-clad stems radiating from an offsetting base, rather than flattened rosettes. It is not readily distinguishable from Haworthia coarctata var. coarctata, if not for the provenance and, may be, for the firmer leaves, each about 12-25 mm long and 5-20 mm broad at the base. The leaves are dotted with white, slightly raised, tubercles. Its leaf colour can vary from green to reddish brown dependant upon the amount of light it receives.
