■base, the outer more or less spreading. Glands connected into a 

 ring. Stigmas 5, filiform or subulate, as long as or exceeding the 

 stamens. Ovary half or more then half superior, v/ith 6 cells; pla- 

 centas on the floor of the cells. Capsule very shortly and 

 hro^'dly spreading obconic belov;, slightly convex and with 6 slightly 

 raised valvular sutures above; valves widely spreading or recurved 

 when expanded; expanding-keels with thin edges very closely ex- 

 panding-keels with thin contiguous into a stout central keel for 

 most of their length, enlarging upv/ards, then diverging at the 

 tips, minutely toothed on the inner edge, and with brofid marginal 

 wings reaching to the tip of the valve and olstusely rounded at the 

 apex; cells roofed v/ith semi-transparent cell-wings; slightly com»- 

 pressed, smooth, 



Snecies 3, natives of ^outh-west ^^-frica. I^e type of the 

 genus is V. Sch^antesii, N. E. Br. 



The name is derived from the Latin, ve:^ruca, a v/art, and fero, 

 to bear, in allusion to the v/hite warts borne at the tips of the 

 leaves. 



The snecies of this genus were included by "^chv/antes in Titan- 

 opsis, but they differ from that genus by the stamens not being 

 collected into a cone, by the half^superior ovary, and by the differ- 

 ent expanding-keels of the fruit, v;hile the subclavate, v^^hite- 

 warted, more numerous and more ascending leaves offer vegetative 

 distinction that is very obvious. 



Key to the Species. 



Flowers subsessile, shorter than the leaves, v;hich are 

 covered v;ith ^-arts at the apex for 2-3 lines of their 

 length, Schwantesii, 



FloY.'ers on pedicels 6-7 lines long and as long as or longer 

 than the leaves, v.-hich are covered with v/arts at the 

 apex for only about 1^ line of their length, 2, Luderitzii. 



Flowers unkno^'Ti; leaves with fev/er end larger warts than 



in the above species, 3, Hugo-Schlechteri. 



1,— V. Schwantesii, N. E. Bp,— (Fig, 213 and 214, C.). 

 Rosettes, li-lc inch in diameter. Leaves crowded, ascending, 6-9 

 lines long, 2^-4 lines broad and 2-3 lines tuick at the apical 

 part, clavately semiterete, brordly rounded at the apex, flat on 

 the face, rounded at the back, glabrous and smooth for most of 

 their length with from 2-3 lines of the anical part covered with 

 white or whitish tubercle s or v.-arts 'lomposed of mihute lime-cells, 

 the smooth part being light green, tinted v/ith purplish at the basal 

 part. Flowers siibsessile, shorter then the leaves, ^alyx very 

 shortly obconic below; lobes about 3 lines long and 1^-2 lines broad, 

 deltoid, obtuse, v;ith a fev/ sm^ill tubercle son the back at the apex 

 like those on the leaves. Corolla 9-10. line'- n diameter; petals in 

 1 or § series, about 4-5 lines long, i-i line broad, lineer, obtuse, 

 yellow. Stamens 6, subulate, about as long as the stamens. Capsule 

 4-5 lines in diameter when closed, very shortly end boradly obconic 

 belov, slightly convex, vdth six slightly raised sutures above, pale 

 grey outside and pale brownish inside, v.-ith ochreous-brown expanding- 

 keels that are contiguous into a stout, club-shaped central keel for 

 three-quarters of their length, diverging at the tip,s with broad, 



hatchet-shaped, obtuse marginal wings; cells roofed with semi-trans-
