revolute at the tips, slightly recurved at the margins, the adnate 
lower part prominent from the column, concave down the back or 
with the margins somewhat recurved, very truncate at the base ; 
staminal column about } lin. long ; anther-appendages deltoid or 
ovate-lanceolate, acute, erect, shortly overtopping the truncate 
style-apex ; follicles erect and slightly diverging, about 3 in. long 
and 2 lin. thick, linear-fusiform, tapering into a slender beak, 
smooth, glabrous. Harv. Gen. S. Afr. Pl. ed. 2, 241 ; Schlechter in 
Journ. Bot. 1897, 291. 
Var. 8, grandiflora (N. E. Br.); sepals 4 lin. long, ovate, acute; corolla 
sparsely and minutely puberulent on the outside like the pedicels, with lobes 
14 in. long ; corona-lobes often with a minute tooth near the apex, apparently not 
recurved at the tips ; otherwise exactly as in the type. : 
Katanari Recion: Orange River Colony ; Sand River, Burke! Bechuanaland ; 
near the sources of Kuruman River, Burchell, 2498! Var. 8: Transvaal ; near Warm 
Baths, Tandler in Transvaal Herb. ! 
Also recorded from Tropical Africa (Rhodesia) by Dr. Rendle in Journ. Bot. 
1905, 44, but I have not seen a specimen. 
Burchell in a MS. note states that the Bechuanas call this plant ‘‘ Klokwe,” 
and adds, ‘‘ These roots, being considered an article of food, were brought by a 
Bachapin, of whom I purchased them.” According to Mr. Tandler the roots of 
var. 8 are ‘*much eaten by the natives,” who call the plant ‘‘Seruch.” 
Burchell’s specimens are nearly leafless at the flowering part, whilst the others 
quoted bear leaves at nearly all the flowering nodes. 
XXXIX. RIOCREUXIA, Decne. 
Calyx 5-partite. Corolla tubular, more or less inflated at the 
base, straight, 5-lobed ; lobes linear, erect or incurved-erect, connate 
at their tips, very slightly overlapping in bud, not strictly valvate. 
Corona 2-3- (very rarely 1-) seriate, arising from the staminal 
column ; outer corona-lobes 5, alternating with the anthers, either 
minute and bifid or deeply divided, or conspicuous and radiating, 
filiform, subulate, narrowly deltoid, ovate or subrectangular, free or 
connate at the base, with or without a series of 5 pairs of teeth 
alternating with them at their base ; inner corona-lobes 5, linear or 
subulate and usually equalling or exceeding the anthers and incurved 
over them, or shortly linear-oblong or minute and not reaching 
beyond the base of the anthers, rarely obsolete. Staminal column 
arising from or near the bottom of the corolla, very short and 
together with the corona included in the inflated part of the corolla ; 
anthers erect or ascending, oblong, tipped with a minute somewhat 
fleshy appendage or apiculus. Pollen-masses erect, pellucid just 
beneath the apex, solitary in each anther-cell, attached below their 
middle by exceedingly short caudicles in pairs to the pollen-carriers. 
Style not exceeding the anthers, truncate at the apex. ollicles 
linear-terete or linear-fusiform, acuminate, more or less beaded from 
constrictions between the seeds, smooth. Seeds crowned with a tuft 
of hairs. \
