This is a small erect shrub, apparently not more than a foot 
high, with internodes 4-9 lines long; the leaves, pale above, 
pallidly glaucous beneath, are 5-10 lines long, 3 lines broad, 
with nearly parallel sides and rounded extremities, the petiole 
being scarcely ^ line long, with a curved reflected spine of equal 
length. The raceme is 3 lines long, bears three to five divari- 
cated pedicels | line long, with an oval bract at base one-fourth 
of its length ; the flower, cruciately expanded, is 2 lines in diam. ; 
the sepals are glabrous within, the filament being half their 
length.
