linear, acute, nearly three lines long; rostellum short without arms, 
with two lateral, ciliolate tubercles between it and the side petals; 
anther horizontal; ovary 5 lineslong. D. maculata, Harvey, in Hook.

Has. Grassy places on Table Mt., below, and not far from, Maclear’s Beacon, 
at about 3300 ft. Fl. late in Noy. and beginning of Dec., somewhat rare; Harvey, 
Bolus, 4849 ! 
The leaves are a dark green; the older flowers point upwards, the 
younger downwards; sepals a dull ochraceous yellow, and the odd sepal 
has two brown, eye-like, dorsal spots; the sepals and lip project 
forward. The rostellum with its fleshy side appendages, the absence 
of arms, and the consequent close approximation of the glands, shows 
an affinity with the section Monadenia, but the structure of the 
_ perianth is very different. Itis closely allied to D. uncinata in habit 
and structure, but is at once distinguished by the pointed galea; the 
last-named, however, does not occur within our limits.

18. Disa cornuta, Swartz, in Kongl. Vetensk. Acad. Nya Handl., 
vol. xxi. (1800), p. 210.—An erect, stout, glabrous herb, 12-18 in. high; 
scape densely leafy; leaves lanceolate, acuminate, undulate, sheathing 
at base, erect-spreading, the lower 4-8 in. long, the upper passing 
gradually into sheathing bracts; spike many-flowered, 5-9 in. long, 
13-22 in. wide; bracts lanceolate-acuminate, somewhat longer than 
the flowers; side sepals very broadly oblong, or nearly square with 
rounded corners, apiculate, deflexed, about 6 lines long; odd sepal 
galeate, horizontal, much inflated, obtusely pointed, the spur immedi- 
ately deflexed, the whole about 14 in. long; petals falcate, upcurved 
at the apex, rounded and somewhat eared at base; lip broadly obovate, 
very obtuse, convex on the upper surface, spreading, 4-5 lines long ; 
anther very short and rounded, horizontal; rostellum short; ovary 
8-angled. Thunberg, Flor. Cap. (1823), 7; Orchis cornuta, Linneus,

Has. Amongst bushes on the sandy downs eastward of Cape Town, also on the 
mountain sides and tops up to the summit of Table Mt. (3560 ft.), fl. Oct.—Dec., 
according to altitude. Frequent, but nowhere abundant in one locality. Burchell, 
538 ; Bolus, 4505; Herb. Norm. Austr.-Afr., 565.— The species extends eastward to 
Port Elizabeth and Grahamstown (Burchell, 3680, 3856, 40380). 
Leaves often somewhat glaucous; the odd sepal a dull leaden 
purple; the sepals nearly white; the lip whitish below, the upper half 
of the upper surface a deep velvety purple. The species is a handsome
