362, according to Gilg in Kunene-Sambesi Exped, 334, is a mixture of 2 species, one 
of which, collected by Afzelius in Sierra Leone, may be a var. of WN. leselioides ;

able from NV, congolana, De Wild. & Durand. 
3. N. robusta, Hua in Bull. Soc. Bot. France, xlviii. 261 and 265. 
Plant more robust than JN. lwselioides, Benth., 10-12 in. high, branch- 
ing at the base. Leaves up to 2} in. long, 2—3} lin. broad, very shortly 
connate, lanceolate-linear, obtuse, slightly constricted at the base ; 
lower in rosettes followed by a very small number of sterile leaves ; 
upper bract-like, mostly longer than the calyx. Inflorescence oecupy- 
ing nearly the whole plant, racemose. Flowers subsessile. Calyx 
equally and prominently 8-ribbed ; teeth half as long as the tube, acute. 
Corolla about 5 lin. long, longer than the calyx; tube slender, slightly 
enlarged at the throat; lobes ovate, acute. Stamens included, 1

4. N. rupicola, Hua in Bull. Sec. Bot. France, xlviii. 262 and 
266. Perennial, simple or branched. Leaves opposite or ternate ; 
lower forming a grass-like tuft, linear, 1-1} lin. broad, 1-nerved, with 
thickened margins, falling away after the elongation of the stem, 
leaving annular scars; stem-leaves much shorter and mostly flower- 
bearing, equalling or shorter than the calyx. Flowering-stems often 
crowned with a tuft of leaves. Calyx as in V. robusta, Hua. Corolla 
4 in. long, twice as long as the calyx-tube. Anthers oblong, scarcely 
apiculate. Style almost exserted; stigma 3-lobed, revolute. Ovules 
about 20.

5. N. Schlechteri, Gilg ined. Plant, in the only specimen seen, 
16 in. high, glabrous, annual? Stem slender, with one branch near ti u 
top. Leaves in about 12 distant pairs below the inflorescence, 3—6 lin. 
long, }—2} lin. broad ; lower elliptic-ovate, obtuse, more or less narrowcd 
into a petiole; upper sessile, erect, linear or linear-lanceolate, obtuse. 
Inflorescence about 34 in. long, consisting of 5 distant pairs of flowers 
and a lateral erect branch with 3 flowers. Pedicels 14-6 lin. long. 
Calyx-tube 24-3 lin. long, equally and prominently 8-ribbed ; lol es 
1 lin. long, deltoid, very acute. Corolla whitish in the dried state,
