170 ORCHIDS OF THE CAPE PENINSULA. 
Has. In Farmer Peck’s Valley, Muizenberg, by a mountain stream, at 1100 ft. 
high; Noy., 1883; Bolus! 4893; hills behind Simon’s Town; McKellar’s farm, near 
Care Point, Nov., Dr. R. Marloth. 
Flowers blue-purple, except the upper limb of the petals and the 
spur, which are pale yellow; anther-cells pink. Nearly allied to D. 
graminifolia, but, besides the differences of stracture given, it will be 
noted that the flowering season is quite different. The species seems 
to be confined to the southern part of the Peninsula; on the most 
northern station (the Muizenberg) I only found two specimens; near 
Simon’s Town it is more frequent ; and more abundant still further to 
the southward. 
42. Disa barbata, Swartz, in Kongl. Vetensk. Acad. Handl., vol. 
xxi. (1800), p. 212. — Glabrous, erect, 1-2 ft. high; leaves 4-6, all 
radical, linear, grass-like, lax, shorter than the scape; scape slender, 
subflexuous, distantly clothed with acute membranous sheaths; raceme 
laxly 1-4-flowered (mostly 2-3-flowered) ; bracts ovate, acute, shorter 
than the ovary; side sepals oblong, acute, spreading, about 10 lines 
long ; odd sepal galeate, ovate, acute, including the conical flattened 
spur about an inch long; petals knee-bent in the middle, the upper 
part dilated, sub-bilobed, and toothed, the lower part rounded, obtuse; 
lip oval, lacerate-multifid with inflexed segments, deflexed, about 8-9 
lines long; anther horizontal, the single gland triangular, emarginate at 
base; rostellum 3-lobed, erect ; ovary terete, decurved. 
Has. Amongst Restiones and shrubs, Cape Flats, near Rondebosch, &c., 
frequent ; fl. Sept.—Oct.; Zeyher, 1567; Bolus, 4857; Herb. Norm. Austr.-Afr., 166. 
The flowers are nearly white, the galea marked with pale blue 
veined lines, the side sepals tinged with pink on the thickened middle 
line below, the petals with pale purple veins, the lip pure white. 
The species (as it grows about Cape Town, at least) is very distinct 
from all others, and constant in its chief characters as above noted, 
the only variations I have noted being in the incision of the upper lobe 
of the petals. It is the earliest of this group to flower, coming out at 
the end of September and the first half of October. 
PuatE 8.—Fig. 1, odd sepal (seen from below), side sepals (upper and under 
side), and lip x 1} diameters; 2, petal x 6; 3, column, side view, x 6; 4, ditto, front 
view, x 6; 5, 6, pollinia, magnified. 
43. Disa venusta, Bolus, in Journ. Linn. Soc., vol. xx. (1884), 
p. 482.— Glabrous, erect, 14-24 ft. high ; leaves 6-12, radical, linear, 
grass-like, subcomplicate, shorter than the scape, laxly spreading, 
2 lines wide; scape slender, straight or flexuous at the top, the buds 
only nodding, distantly clothed with closely appressed, acute sheaths ; 
raceme laxly 3-6-flowered ; bracts broadly ovate, acute; side sepals 
oblong, acute, mucronate below the apex, deflexed, about 8 lines long,
