Description

One of our tiniest orchids only growing up to 10cm. It is very seldom seen, mostly second year post-fire. The leaves are stiff and leathery, overlapping and almost folded together. The flowers are either dark maroon or greenish-yellow and resupinate (lip is lowermost petal). The lip is papillate (has small pimple-like projections), except along the margins. The yellow colour form comprises only 12% of the plant populations. Acrolophia ustulata is referred to as the 'black orchid' and is one of only 2 Cape orchids to have the maroon-black floral colouration. This species is listed as Vulnerable in the Red Data List. It appears to be highly sensitive to fire intensity. It is known from only 5 locations. Acrolophia from Greek meaning crests on lip: akros, end or summit; lophos, crest. Latin ustulatus refers to the burnt, seared look of flower; ustus - to burn, -atus - likeness to.
