Also in the Transvaal. Very similar to J. ewilis, but distinguished by the 
tubercled palate. Dinter’s specimen from Waterberg was described by Kamienski 
as U. exilis, var. hirsuta, on account of the supposed presence of a dense tomentum 
of short hairs. I had an opportunity of examining the very specimens from which 
Kamienski described this variety, but was unable to find any hairs. The only thing 
that resembled hairs was a fine layer of an (Zdogonium which coated the lower 
portions of the scapes. I also found apparently the same alga (in fructification) on 
the Transvaal specimens of U, Kirkii. The alga creeps up the scapes closely 
adpressed to them with the exception of the ends of the threads, which sometimes 
diverge, 
6. U. exilis, Oliver in Jowrn. Linn. Soc. ix. 154. A delicate, 
very dwarf, terrestrial herb; stolons filiform, moderately branched. 
Leaves often decayed at the time of flowering, in small fascicles at the 
base of the scape or scattered along the stolons, narrowly spathulate or 
ligulate, narrowed into the long, slender petiole, up to 3 (or even more) 
lin. long, f-} lin. broad. Bladders from the stolons and leaves, sub- 
globose, about 4~2 lin. long, upper lip broadly elliptic, as long as the 
bladder is wide at the mouth, lower very short, both lips fimbriate. 
Scape capillary, 1-2 in. high, 1—3-flowered, straight, simple, rarely with 
1-2 branchlets. Flowers, if more than 1, distant; bracts and bracteoles 
subequal, ovate-lanceolate, } lin. long; pedicel about as long as the 
bracts. Sepals orbicular to broad-elliptic, the upper usually broader, 
2 lin, long. Corolla 14-24 lin. long, white, yellow or more or less 
purplish, with a yellow palate, which is sometimes streaked with 
purple ; upper lip subquadrate or subobovate from a short broad base, 
slightly emarginate, fleshy, 2—1 lin. high ; lower lip subquadrate or 
Somewhat broader than long, obscurely undulate, 3-1 lin. long, palate 
Smooth with obscure ridges; spur straight or curved, wide funnel- 
Shaped at the base rather suddenly contracted at or below the middle, 
then cylindric, obtuse, straight and subhorizontal or curved upwards. 
Anther } lin. long. Style very short, but distinct, conical; upper lip 
of the stigma ovate to semi-orbicular, half as long as the obovate- 
quadrate lower lip. Capsule globose, 1 lin. in diam. ; seeds irregularly 
hemispheric or hemi-ellipsoid, more. or less angular, to~» lin. long, 
Sometimes compressed and almost transparent near the hilum, top face 
with a clean edge.—Hiern in Cat. Afr. Pl]. Welw. i. 788; Kam. in
