478 T'XXV. campanulacej: (hemsley). [Wahlenbergia. 



Annuals usually a foot or more high ; perfect stamens 5. 



Crtlyx-lobes lanceolate obtuse, erect, equalling the tube 8. W. inhambanensis. 

 Calyx-lobes thick, half as long as the tube .... ^. W. riparia. 

 Calyx-lobes slender, lanceolate acute, nearly as long as 



the tube 10, JT. etbaica. 



1. W. arg'uta, Hooh. fil. in Joum. Linn. 8oc, 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 

 Howers 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.

 Mountains, 7000 to 10,000 ft., Mann ! 



2. W. silenoides, Hoclist. 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. Mannii. 



wile l^and. Abyssinia, Sckimper ! Roth ! 



Schimper 8 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 in the 

 calyx-lobes and the less hairiness of the stem and leaves. 



3. W. Zllannii, Vathe in Linncea^ 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 furnished 

 with a few minute callosities. Calyx glabrous, about 4 lines long, 

 the cylindrical tube nearly twice as long as the ovate-lanceolate sub- 

 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. Soo. vi. p. 15, not of 

 A. DC. 



Upper Guinea. Clarence Peak, Fernando Po, 9000 ft., and Cameroons Moun- 

 tains, 7000 to 8000 ft., Mann ! 



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.
