1. W. arguta, Hook. fil. in Journ. Linn. Soc. vi. p. 15. A pilose 
or almost glabrous herb with slender leafy ascending stems about a 
foot high, dichotomously branched into long naked peduncles. Leaves 
sessile oblong-lanceolate acute or obovate, of a harsh texture in dried 
specimens, deeply serrated, puberulous pilose or quite glabrous, 3-9 lines 
long. Peduncles 6 in. or more long with usually about 3 pedicellate 
flowers at the top. Calyx glabrous about 3 lines long, the lanceolate 
acute lobes twice as long as the turbinate 10-nerved tube. Corolla pale 
blue narrow-campanulate, 4-5 lines long; lobes about a third of the 
whole length. Capsule more than half-superior 3-celled, turbinate at 
both ends scarcely exceeding 2 lines in length.

2. W. silenoides, Hochst. in Rich. Fl. Abyss. ii. p. 3. Of the 
same habit and floral characters as W. Mannii, but the young leaves 
and stems are almost entirely glabrous, and the calyx-lobes are linear- 
lanceolate. The short woody stem or root-stock bears a tuft of slen- 
der virgate branches, clothed with small lanceolate-elliptical almost 
glabrous leaves, which are more distant in the upper part, giving the 
peduncles a less naked appearance than those of W. Manni. 
Mile Land. Abyssinia, Schimper! Roth! as 
Schimper’s number 998 is the typical plant, and is perhaps sufficiently distinct, 
but his 928 has larger leaves and is otherwise more like the preceding, except 1n the 
calyx-lobes and the less hairiness of the stem and leaves. 
_ 3. W. Mannii, Vatke in Linnea, xxxviii. p. 700. A tufted herb, 
with numerous slender ascending branches rising from a relatively 
stout woody root-stock; branches 6-18 in. high, leafy in the lower 
part and clothed with a loose tomentum of long white hispid hairs, 
glabrous upwards and terminating in a long naked simple or slightly 
branched peduncle. Leaves crowded sessile ovate-lanceolate acute 
more or less hispidly pilose when young especially along the midrib 
on the lower surface, margin white cartilaginous undulate furnishe 
with a few minute callosities. Calyx glabrous, about 4 lines long, 
the cylindrical tube nearly twice as long as the ovate-lanceolate suD- 
obtuse lobes. Corolla very small, scarcely 2 lines long. Capsule 
wholly inferior, 2-celled, cylindrical, narrowed at the base, 4-7 lines 
long.—W. polyclada, Hook. fil. in Journ. Linn. Soc. vi. p. 15, not of

This and the next are probably races of one species, but in the absence of more 
complete material it is convenient to keep them separate,
