CONSPECTUS TABULARUM. oe 
The genus Bouchea has representatives as well in North Africa as 
in America and the peninsula of India. There are 6 8. African species 
natives of the Northern and Eastern districts. That now figured is the 
commonest, and will serve as an illustration of the genus. The others 
have a very similar habit and flowers, and differ chiefly in foliage.

XXIX. CROTALARIA PLATYSEPALA, Harv. — (Leguminose.) 
C. platysepala: fruticosa, ramis tenuissime puberulis, stipulis se- 
taceis, foliis trifoliolatis, foliolis petiolo vix longioribus elliptico-oblongis 
mucronulatis supra glabris subtus appresse pubescentibus, racemis ter- 
minalibus elongatis multifloris, calycis pubescentis profunde 5-fidi laci- 
niis obovato-oblongis cuspidato-mucronatis infimo angustiore, vexillo 
pubescente, alis amplis carina longe rostrata vix brevioribus, ovario 
pubescente stipitato, 6-8-ovulato; legumine? 
Has.—In sandy soil, between the rivers Tamulakau and Zougha, beyond the Lake 
 Ngami, Jos. M‘Cabe. (Herb. Hook.) 
Drscr.—* A shrub.” I have only seen the tips of flowering branches. 
Leaves trifoliolate, subdistant, spreading, the petiole 2-1 inch long, 
nearly as long as the leaflets, the middle leaflet longest, 2-8 lines wide. 
Stipules very slender, much shorter than the petioles. Racemes 5-6 
inches long, gradually lengthening, 20-30 flowered. Flowers bright- 
yellow, minutely silky, 4 inch long. Calyx-segments oblong, abruptly 
subtruncate, and mucronate, all of equal length, but the lowest one nar- 
rower than the others. Legume not seen. 
Though this plant scarcely comes within our geographical limits, I~ 
figure it as a sort of ‘‘ first fruits’? of the Botany of Lake Ngami, and 
on account of its remarkable calyx, so different from that of any other 
8. African species. 
Fig. 1, Crotalaria platysepala ; a flowering twig, the natural size. Vig. 2, side view 
of an unopened flower, just before anthesis; 3, the calyx laid open, in side view; 4, one 
of the ale; 5, ovary andstyle. The latter figures variously enlarged. 
XXX. LORANTHUS NATALITIUS, Meisn. (Loranthacee:.) 
L. natalitius: glaberrimus, ramis-virgatis teretibus, foliis sparsis 
‘(nune per paria approximatis) lanceolato-oblongis v. obovatis obtusis 
“basi cuneatis breve petiolatis tenuissime 3-5 nerviis, floribus ad apices 
ramulorum umbellatis, pedicellis calyce subtriplo longioribus, calyce tur- 
binato perbrevi sub-repando-dentato, corolle tubo 2-uncias longo cylin- 
draceo demum hine fisso, fauce angustata, limbi 6-5-fidi laciniis lineari- 
lanceolatis acutis vix secedentibus, staminibus fauci insertis erectis,
