Xi/smalobium.] lxxxv. asclepiade.e (browx), i]07 



10. X. dispar, X i^\ Br. Stem moderately stout, tomentose, at 

 least in the upper part, as well as the peduncles, pedicels and bracts. 

 Leaves numerous, ascending ; petiole 1-;") iin. long ; blade o-D in. long, 

 J-l|- in. broad, lanceolate, gradually tapering from a little above tlie 

 more or less truncate base to an acute mucronate point, margins 

 narrowly revolute, scabrous, both surfaces minutely sc^brid-pubescent, 

 or the lower surface minutely tomentose when young, the pubescence 

 becoming more scattered and more or less deciduous on the older leaves. 

 Umbels several, pedunculate, lateral at the nodes along the upper part 

 of the stem which is sometimes leafless in the apical part ; peduncles 

 J-1 J in. long ; bracts 2-5 Iin. long, linear or subulate, acute ; pedicels 

 6-11 Iin. long. Sepals 4-6 Iin. long, f Iin. broad, equalling or shorter 

 than the corolla, flat, lanceolate-attenuate, spreading, softly pubescent. 

 Corolla lobed almost to the base, campanulate, or rotate-campanulate(^), 

 apparently white ; lobes 4-5 Iin. long, 2 Iin. broad, oblong, acute, con- 

 cave, glabrous outside, tomentose with white hairs at the recurving 

 apex and the margins within. Coronal-lobes arising from the widened 

 base of the staminal column, spreading, very shortly adnate to the 

 bottom of the corolla at the base, then erect and scarcely reaching to 

 the base of the anthers, 1 J Iin. long and as much in breadth, broadly 

 ovate or rhomboid-ovate, apparently slightly reflexed at the sides, 

 obtusely pointed, with a thick obtuse keel down the face, which forms an 

 obtuse incurved point at the apex. Staminal -column :> Iin. long, with 

 well marked furrows at the junction of the filaments, which do not 

 appear to be quite free as in X. harhigei'um ; anther appendages 

 broadly ovate, or orbicular, obtuse, inflexed over the truncate apex of 

 the style which is not exserted beyond them. Follicles large "furrowed 

 at the apex" (Ilohtb), 4J-5 in. long, lj-l| in. thick, pubescent and 1)6- 

 set with soft flexuose hairy bristles .^-J in. long. — Xi/smalobium lapat/ii-

This species is closely allied to A", ensifolium, Burch., and X. undulatum, W. lir. 

 From the former it differs in having the coronal-lobes at the hnse of the staiiiiiial- 

 column and scarcely reaching- to the Imse of the unther-wings ; from the lattt-r it 

 differs in its narrower leaves, narrower and longer sepals, nnrrower, more acute and 

 apparently thinner petals, which are less densely bearded at the tips with shorter 

 hairs than in X. undulatum. It also resembles A', angolense, Scott-Elliot, but the 

 apex of the style is not exserted beyond the anther-a])|)enda^ts and the tihuncntal 

 part of the staminal-column is quite half its entire length, wliilst i)i A', anrjolense 



11. X. barbigerum, X. K. Br. Stem probably tall, rather 

 robust, tomentose. Leaves opposite, ascending or incurved-ascending ; 

 petiole \-\ in. long, tomentose or densely pubescent ; blade '{-5 J, in. 

 long, 6-10"lin. broad at the base or larger (?), long and narrow, gradually 

 tapering from the base to the acute apex, subtruncate or obtuse at the 

 base, longitudinally folded, pubescent on both sides. Umbels lateral at 

 the nodes, racemosely arranged along the upper part of the stem KJ-HI-
