Haworthiopsis koelmaniorum (Oberm. & D.S.Hardy) Boatwr. & J.C.Manning var. mcmurtryi (C.L.Scott) Gildenh. & Klopper
Vulnerable Indigenous Endemic

Morphological description

Plants acaulescent, with leaves in a basal rosette which is about 70 mm diam., solitary. Leaves about 14, the young recurved, the old recurved with a convex retuse end-area; about 20-40 mm long, 12 to 18 mm broad and about 18 mm thick at the base of the end area, oblong, acute to deltoid; face below end-area concave, smooth, yellow whitish-green, dull, lineate; end-area retused, about 18 mm long, 10-17 mm broad, flat or convex, little turgid, pellucid, with numerous rounded concolorous tubercles arranged in longitudinal rows, becoming minute near the apex, green, shining, with 3 to 6 distinct longer and shorter whitish-green veins, these becoming tessellately connected towards the lower end of the retused area; end-area 0.5 mm long, white, curved; back surface rounded, smooth below, with tubercles arranged in transverse rows on the underside of the retuse area; keel 1, oblique, acute below, more or less rounded above with sharp 1 mm long, spaced pellucid teeth, becoming minute towards the base of the leaf.

Diagnostic description

H. mcmurtryi shows affinities with two species, H. asperula Haw. and H. koelmaniorum Hardy & Mauve. From the first, H. asperula, it differs in the tubercles being rounded and not terminating in a sharp point and in being solitary, while H. asperula has leaves smooth underneath, with a few oblong pellucid flecks; the distribution of the two species (as far as present records serve) are very remote from one another. H. asperula occurs in the coastal region and at a lower altitude than H. mcmurtryi. From the second, H. koelmaniorum it differs in that H. koelmaniorum is a larger plant, not retuse-leaved, with tubercles on both leaf surfaces; there is also a difference in the shape of the leaves.

Habitat

Within its distribution range the rainfall may vary between 400 and 600 mm which falls during the summer months, usually as short, violent downpours. The summers are hot, and frost in winter occurs throughout this area, which is covered by grassland of various types. H. mcmurtryi occurs in reddish brown soil on quartzite hills, mainly well withdrawn when growing in exposed positions, and generally tightly packed amongst small quartz pebbles; or well shaded in clumps of tall grass.

Distribution

H. mcmurtryi occurs in a small area in the Central Transvaal. From: Scott, CL. 1985. The genus Haworthia (Liliaceae): a taxonomic revision. Aloe Books, Johannesburg. [All rights reserved] As: Haworthia mcmurtryi C.L.Scott
