_ According to Decaisne this is not the true Asclepias laniflora of Forskal, but on 
this point he is certainiy mistaken, as there is a specimen, received from Forskal, 
n the British Museum Herbarium, which I have examined and found to be identical 
with the plant here described. [t was upon this specimen that Robert Brown 
founded the genus Kanahia, although his description of the coronal structure is not 
very exact. I have not seen any example from Africa of the plant which Decaisne 
has described under the name of Kanahia Forskalii, which has shortly bifid coronal- 
lobes, something like those of K. consimilis, N. E. Br., but not so deeply bifid, and 
the pollen-masses are quite different. 
. The solid structure of the coronal-lobes of K. laniflora is evidently only a varia- 
tion of that which usually obtains in Asclepias, and is formed by the soldering 
together of the inflexed sides of an ordinary complicate coronal-lobe ; indeed, this is 
completely demonstrated in a specimen collected in Eritrea at Ginda (Schweinfurth 
Riva, 2148), in which the top of the coronal-lobes is deeply furrowed all along, 
forming an intermediate stage between the entire coronal-lobes of typical X. lani- 
flora and the deeply cleft lobes of K. glaberrima. The pollen-masses, however, are 
short as in K, laniflora. 
2. K, glaberrima, V. £. Br. Stems 4—6 ft. or more high, simple 
= branched, glabrous, except some minute bristles in the axils of _the 
“aves and along the rudimentary stipular line. Leaves ascending ; 
Petiole 1-4 lin. long; blade 2-6 in. long, 2-7 lin. broad, broadly linear 
7 linear-lanceolate, tapering to an acute point, acutely narrowed into 
the petiole, slightly thickened along the margins, quite glabrous. 
wers in pedunculate several-flowered bracteate umbel-like racemes

© leaves ; peduncles 14-24 in. long, glabrous; outer bracts 4-6 lin. 
ong, the succeeding ones gradually smaller, deciduous, glabrous ; pedicels 
lowe, lin. long, glabrous. Sepals 1}~4 lin. long, varying from ovate- 
“nceolate to linear-lanceolate. Corolla deeply 5-lobed, somewhat reflexed 
°r, n the dried state, often more or less campanulate), whitish ; lobes
