A native of Cape Colony, gathered by Mr. Cooper. 
Leaves about thirty in a dense sessile tuft more than two 
inches across and rather over an inch high, ovate, narrowed from 
the middle to a broad base and gradually upwards to an acute 
point, when fully developed fifteen lines long by half an inch 
broad, a quarter of an inch thick in the middle, the face nearly 
flat, the back rounded and rather sharply keeled, mottled towards 
the tip on the face and half-way down the back with distinct 
small white granules, the rest of the surface a pale glaucous 
green, but the colour deeper between the spots and both sides 
with about half-a-dozen darker vertical ribs. Peduncle five to 
six inches long exclusive of the raceme. Bracts three to four 
lines long, lanceolate-cuspidate, equalling the erecto-patent pedi- 
cels. Perianth eight to nine lines long, pure white with green 
ribs ; the divisions subequal, and nearly regularly falcate when 
expanded, half as long as the tube. 
Nearest H. Icetevirens, Salmdyck, section 10, fig. 3, in habit, 
and remarkable in the genus for the nearly regular limb of the 
perianth, in which it approximates to Aincra.

In this and the two following species of Haicortliia (Tabs. 
233 and 234) will be found nearly allied plants, but with 
diflerences which up to the present time have been considered 
specific. Under cultivation they are easily distinguishable, and
