oblong, obtuse, the middle one 1-1} lin. long, the lateral shorter. 
Stamens inserted at the base of the upper lip of the corolla, and the 
longer pair almost equalling it in length ; filaments broad and flat, 
cohering by means of the interwoven hairs with which they are 
ciliate. Style glabrous.

This species is very similar to L. pallida, Benth, but is readily 
distinguished by the orange-scarlet (not pale yellow) colour of the 
corolla, which is much less gibbous on the back of the upper lip, 
and has the rings of hairs in its tube placed much nearer to the base 
than they are in L. pallida. 
NYCTAGINEAE. 
Boerhaavia plumbaginea, Ca 
, Car. 
By the Lake River, Lugard, 14; Kwebe Hills, 3,300 ft., Mrs. 
Lugard, 21, 
A perennial, growing to a height of 4-6 ft. ; flowers white. 
Boerhaavia adscendens, Walid. 
Botletle Valley, Lugard, 198. 
swamp weed ; flowers purple. There are only young buds 
on the specimen, but it appears to be this species. 
Boerhaavia pentandra, Burch. 
Bechuanaland ; near Palapye, 3,000 ft., Lugard, 276. 
Creeping on the ground ; flowers magenta. 
AMARANTACEAE, 
Hermbstaedtia scabra, Schinz. 
Kwebe Hills, 3,300 ft., Lugard, 151; Mrs. Lugard, 196. 
An annual, 2-4 ft. high; flowers pirk. This is evidently a 
dimorphic species, the staminal-tube is longer, and the ovary more 
attenuated in some specimens than in others; they probably 
represent sexual forms. 
Hermbstaedtia elegans, Mogq. var. 
Near Bachakuru in the Kalahari Desert, Lugard, 236. 
Flowers purplish-white. 
_ Bericocoma sericea, Schinz. 
Kwebe Hills, 3,000 ft., Lugard, 181; Mrs. Lugard, 165. : 
Annual, growing to 2 ft. high; flowers green or dirty-white, 
with the terminal part of the stamens chocolate-coloured. 
Sericocoma Bainesii, Hook. /. 
Kwebe Hills, 3,000 ft., Mrs. Lugard, 158. 
A perennial, growing to about 18 in. high; flowers greenish- 
white, 
Sericocoma Welwitschii, Baker. 
Kwebe Hills, 3,300 ft., Lugard, 170 ; Mrs. Lugard, 221, ; 
Plant growing to 23 ft. high ; flowers greenish-white, becoming 
cream-coloured. The two specimens quoted are very different in 
appearance, but I believe them to be the same species in different 
stages of development. . a
