PuNGO Andongo. — A widely caBspitose undershrub, 1 to 2 ft. high 

 and more ; rootstock hard-woody, polycephalous ; stems numerous, 

 simple or rarely forked at the apex, shaggy ; leaves lanceolate, some- 

 what rigid, silky-hoary in the living state with long adpressed whitish 

 remarkably glistening hairs^ crowded, subsessile ; flowers apparently 

 white-rosy, not seen fresh ; heads sessile among leaves longer than 

 themselves ; perianth elongated. In hilly places among low bushes near 

 Bumba, between Quisonde and Condo, in company with L. angolense, 

 seen only in one spot ; fr. March 1857. No. 1589 and Coll. Carp. 889. 



This and the last are the first two species mentioned by Welwitsch, 

 Apontam. p. 579, note 9, and p. 548, n. 80.

HuiLLA. — A small tree, 12 to 20 ft. high or rarely more ; trunk 

 nearly a foot in diameter at the base ; branches spreading, naked 

 below, ramulose and leafy towards the apex ; flowers white ; perianth 

 1^ in. long, hirsute or pilose with white hairs throughout ; the lobes 

 f to I in. long, linear-oblong, not aristate at the apex but subulately 

 cucuUate-corniculate with the little horns concealed among the hairs ; 

 the lip 3-lobed, densely and equally pilose on the whole of the outside 

 including the middle of the back ; anthers shorter scarcely by y^ in. 

 than the perianth-lobes, apiculate, the apiculus consisting of a tolerably 

 large ovoid or elongated-ovoid erect brown somewhat fleshy obtuse 

 gland ; anther-cells found empty in the bud, having dehisced and 

 already shed their pollen ; style glabrous, 2 j^ to 2j in. long, slender, 

 somewhat compressed, furrowed in places, not or but little dilated in 

 the middle, curved a little above the base, above the middle curved 

 equally in the contrary direction, so as on the whole to describe as it 

 were an elongated sigmoid bend ; stigma about f in. long, slender, 

 gradually narrowed upwards, somewhat obtusely clavate-thickened at 

 the apex. In one flower the tri-lobed lip of the perianth was some- 

 what callous on the middle of the back, where appeared an obscure 

 thick nerve. In the more open very mixed forests on a sandy clay 

 soil, at No Monino near Lopollo, and at Quilengues ; fl. Feb. and end 

 of March 1 860, plentiful. No. 1600. A tree, 15 to 25 ft. high ; trunk 

 8 in. in diameter at the base ; ramification somewhat lax ; leaves dis- 

 posed towards the tips of the branchlets, somewhat glabrous ; flowers 

 white, rather rarely rosy ; perianth-segments all 4 densely white-shaggy, 

 not tawny-silky on the back ; involucral scales obtuse, silky-shaggy on 

 the margin. In the Monino forests behind Lopollo, on a sandy clay or 

 mould, plentiful ; fl. Feb. to April 1860. A glabra te form. No. 1602. 

 In the sunny rocky parts of open mixed forests on a sandy clay soil be- 

 tween Lopollo and the Monino, sporadic. A half -naked form. No. 1604. 



The young plants appear to be very different in indumentum from 

 the adult trees ; they are often nearly tomentose and subsequently 

 silky-shaggy ; the leaves also are much narrower and more acute. 

 Welwitsch noticed individuals on which one branchlet bore quite 

 glabrous and another branchlet quite shaggy foliage. 



The following two Nos., without flowers or fruits, should be 

 compared with this species : — 



PuNGO Andongo. — A little tree, about 10 ft. high ; trunk straight, 

 1^ ft. in diameter at the base ; branches long, erect-patent ;
