DISA. 141 
apiculate, spur terete, incurved, obtuse, usually somewhat inflated, 
14-lines long, shorter than the ovary, the whole with spur 34-4 lines 
long; petals somewhat triangular, acute, lobed at the posterior angle, 
nearly as long as the odd sepal ; lip oblong, obtuse, narrowed at base, 
deflexed, 14 lines long; rostellum longer than the short rounded 
stigma, the lateral processes wholly turned back towards the anther ; 
ovary short, obovate, covered with hyaline pustules. 
Has. In sandy places on the Muizenberg Mountain, towards the Steenberg, at 
about 1300 ft., fl. Nov., Bodkin; Herb. Bolus, No. 4970. 
Sepals dull red, petals and lip pale yellow. Allied to M. micrantha, 
which is itself a variable plant, but the columns appear to be different, 
and the caudicles of the pollinia in this seem to be always as long as 
the pollinia,—if, indeed, this be a trustworthy character. It appears to 
be somewhat rare; I never gathered it, and am indebted to Prof. Bodkin, 
its discoverer, for living specimens.

magnified. 
8. Disa cernua, Swartz, in Kongl. Vetensk. Acad. Handl., vol. xxi. 
(1800), p. 211.—-Glabrous, erect, 10-18 in. high; stem mostly robust, 
leafy; leaves 4-6, linear-lanceolate, acute, sheathing at base, 8-5 in. 
long, passing gradually into loose sheaths; spike usually densely 
many-flowered, about half the length of the plant, 1-14 in. thick; 
bracts lanceolate, veined, shorter than the flower; side sepals oval, 
subobtuse, veined, recurved, nearly 5 lines long; odd sepal with an 
arched oval limb, obtuse or emarginate, 5 lines long, with an inflated 
or bag-like, very obtuse, veined, pendulous spur, shorter than the 
ovary; petals obliquely ovate, with a wide base; lip narrow, tongue- 
shaped, obtuse, deflexed, as long as the sepals; rostellum ascending, 
with lateral wings which project for a short distance and are then 
reflexed ; stigma somewhat narrowed in front.—Thunberg, Flor. Cap., 
ed. 1828, p. 12. D. prasinata, Ker, in Bot. Reg., iii. (1817), t. 210.

Has. Lower slopes of the Lion’s Head Mountain, facing the sea, 200 ft., 
fl., Sept., Bolus, 4973. Near Wynberg, Zeyher, 1569.—Extends eastward to Montagu 
Pass, George, 1200 ft., Oct., EH. W. Young. 
The flowers seem to vary somewhat in colour; those I have seen 
on the Peninsula have greenish yellow sepals, and deep red or purple 
petals and lip; the latter is occasionally yellow. The species is easily 
distinguished by its robust habit, combined with its large inflated 
spur. Sonder’s name and description were appropriate and accurate ; 
Thunberg describes the spike as ‘‘ nodding at the apex,’ but I have
