XXXvili. 43. 
CrenrraL Recion: Cradock Div. ; without precise locality, Mrs. Barber, 2! 88! 
Murraysburg Div. ; near Murraysburg, Tyson (ex Schlechter). 
Harvey’s figure and description of this plant is made entirely from Mrs. Barber's 
specimens. On her label of no. 2, she states that ‘‘it is eaten by the Dutch 
inhabitants and much esteemed as a preserve, under the name of ‘ kalkoujes.’” 
Zeyher’s specimen, from near Uitenhage, which Harvey quotes under B, filiforme, 
belongs to B. Zeyheri, N. E. Br. I have not seen a specimen of Dichexlia macra, 
but from the description there seems nothing to distinguish it from B. filiforme, 
the only discrepancies I can find are that in D. macra the leaves are “*J-]3 lin. 
broad, oblong-lanceolate, puberulous on both sides ; pedicels about 1 lin. long; 
united part of corolla 3 lin. long; inner corona-lobes glabrous,” but the minute 
puberulence at their base in B. filiforme is almost invisible when moistened for 
dissection, and with regard to the leaves, on account of the longitudinal folding of 
them, the real upper (infolded) surface may have been overlooked. 
29. B. pygmeum (N. E. Br.) ; tuber turnip-shaped (Bowker) ; 
stems several, simple or slightly branched, erect, 14-3 in. high, 
puberulous ; leaves sometimes undeveloped at the time of flowering, 
spreading, 2—6 lin. long, $-24 lin. broad, linear-spathulate, oblanceo- 
late or oblong-lanceolate, acute or obtuse, cuneately narrowed into a 
short petiole at the base, glabrous on both sides except along the 
midrib beneath, minutely ciliate; flowers 1-3 together, lateral at 
the nodes ; pedicels 14-4 lin. long, puberulous ; sepals about } lin. 
long, linear-lanceolate, acute, puberulous ; corolla usually cage-like, 
with the lobes connate at the tips, but sometimes with free and 
more or less spreading lobes, and both forms on the same specimen ; 
tube about # lin. long, shallowly cup-shaped, glabrous outside, 
puberulous within (the hairs more or less invisible when wetted), 
apparently yellowish or greenish ; lobes 2-3 lin. long, linear from a 
deltoid base, when free varying from nearly straight to circinately 
inrolled at the tips, puberulous at the base on the inner face, other- 
wise entirely glabrous, apparently olive-green or purple-brown ; 
outer corona very variable, even in flowers upon the same branch, 
arising 1} lin. up the } lin.long staminal column, consisting of 
5 minute entire pouches or 5 distinct lobes, which are sometimes 
very minute, at others more distinct and subquadrate, usually 
emarginate or shortly bifid, or the lobes are all connate into an 
entire narrow ring or cup entirely surrounding the column, 
sprinkled on the back and on the column immediately beneath them 
with minute but rather thick or papilla-like hairs and sometimes 
more or less ciliate with them; inner corona-lobes {—{ lin. long, 
linear-oblong, obtuse or notched at the apex, incumbent upon the 
backs of the anthers and not exceeding them, much larger than the 
outer corona-lobes, glabrous. Dichelia pygmea, Schlechter in Journ. 
Bot. 1894, 262, and 1897, 293. 
Var. 8, breviflorum (N. E. Br.); leaves undeveloped at the time of flowering ; 
tube and base of the 2-24 lin. -long corolla-lobes glabrous on the inner face ; outer 
coruna-lobes glabrous or with very few papilla-like hairs beneath, otherwise as in
