DISA. 17! 
34 lines wide; odd sepal galeate, oval, with a scarcely acute point and 
a short flattened spur, about 9 lines long and 5-6 lines wide; petals 
bent at a nearly right angle, the upper part dilated and toothed at the 
apex (sometimes acutely bilobed), the lower part oblong and obtuse ; 
lip ovate-oblong, lacerate into many obtuse, incurved segments, 
6-7 lines long, 3-4 lines wide ; rostellum 8-lobed, suberect; the single 
gland of the pollinia oblong, longer than wide, emarginate below ; 
ovary bent, twisted; capsule erect, straight. 
Has. Amongst Restiones and shrubs on the Cape Flats, near Rondebosch, frequent ; 
also sparingly on the mountain-sides up to 800 ft.; fl. Oct—Nov.; Burchell, 151, 
747; Bolus! 4566.—Extends, I believe, eastward to Grahamstown, and northward 
to the “‘ High Veldt,’’ between Pretoria and the Drakensbergen; the latter a form 
with a two-armed rostellum and two glands. 
The sepals are a cheerful blue, with darker stripes on the galea; 
petals white, tinged with purple; lip creamy white; the spur greenish 
yellow, producing a resemblance to eyes when looking into the flower; 
anther-cells pink; stigma and rostellum white. It always flowers 
after D. barbata and D. lugens, and about the same time as D. purpu- 
rascens. Owing to its similarity to the first when in the dried state, it 
has long been confused with that species in herbaria. It is, however, 
quite distinct.

44, Disa lugens, Bolus, in Journ. Linn. Soc., vol. xx. (1884), 
p. 483. — Glabrous, erect, 14-2 ft. high; leaves 6-12, radical, linear, 
grass-like, nerved and margined below, smooth above, laxly spreading, 
8-15 in. long; scape clothed with several acute, membranous sheaths; 
raceme more or less flexuous, laxly 6—-15-flowered, 6-10 in. long; 
bracts ovate, membranous, acute, shorter than the ovary ; side sepals 
oblong, acute, spreading, 5 lines long; odd sepal galeate, with an 
ovate mouth, 4-5 lines wide, acute, with an ascending spur 2 lines 
long ; petals falcate, acuminately bilobed, dilated and toothed at the 
base; lip oblong, lacerate-multifid, the segments often 2—4-lobed at 
the apex, 5-7 lines long, 4-6 lines wide ; anther horizontal, the glands 
(one or two) oblong ; rostellum 38-lobed, short, suberect; ovary curved, 
8-12 lines long. 
Has. Sandy, heathy downs, eastward of Rondebosch and Claremont, alt. 
60—80 ft.; fl. Noy.; Bolus, 3810; Herb. Norm. Austr.-Afr., 494.—Extends eastward 
to Kuil’s River, Pappe, 39, 377; Ecklon, 1566; and has also been found at Cold- 
stream, near Grahamstown, MacOwan, Galpin. 
The colour of the galea is a metallic greenish purple, sometimes a 
pale lilac ; the side sepals and petals dull purple, the lip bright green. 
This species is by far the tallest and strongest of this section. The
