PuNGO Andongo. — In neglected fields of Phaseolus, near Muta 

 Lucala and Quisonde, abundant ; fl. and fr. March 1857. No. 3236- 



HuiLLA. — No notes. Fl. Simple, or nearly so, 2 to 6 in. high ; 

 flowers rather smaller. Probably a form of this species. No. 3227-

6. T. aprica Hiem, sp. n. 



An erect or ascending, sub-scabrid, annual herb, 4 to 12 in. high ; 

 simple or branched from the base ; stem and alternate branches 

 slender, often purpHsh, scabrid with whitish short hairs above ; 

 upper branches few or lax ; middle internodes mostly longer 

 than the leaves, the lower and uppermost ones shorter; leaves 

 opposite, linear or nearly so, acute or pointed and apiculate at the 

 apex, sHghtly or scarcely narrowed, or in the case of the upper-

 rough, pale grey- green above, yellowish or purplish green 

 beneath, sub-erect except the uppermost ones at the base of the 

 inflorescence, 5 to 1| in. long, uni-nerved; the margins cartilagi- 

 nous, thickened, a little rough ; stipules adnate to the bases of 

 the leaves, sheathing, terminating in a few or several more or 

 less prolonged setae, glabrous and shining inside ; flowers about | 

 in. long, very numerous, slender, sessile or subsessile, in hemi- 

 spherical bracteolate terminal heads of 5 in. in diameter with the 

 one or two uppermost pairs of spreading leaves and their stipules 

 forming a kind of involucre ; bracteoles filiform, not exceeding 

 the calyx ; calyx narrow, compressed, ^ in. long ; the tube 

 small, glabrous except some scattered minute scales ; the limb 

 bipartite; the segments green, opposite, equal, i in, long, 

 narrowly linear-lanceolate, acute, ciliate; corolla white-violet-

 spreading in the open flower ; stamens 4, exserted ; filaments 

 minutely puberulous, inserted at the top of the tube of the
