513 T, Schvantesii in general appearance. Leaves described gs being 



6-8 lines long, 2-2-g- lines bror-d end 1-^-2 lines thick, but probably 

 become larger under cultivation, in form like those of T. ochwantesii, 

 but lAdth the triangular pustular part at the apex sloping backv/ards 

 and making an angle v/ith the smooth upper surfcice of the leaf, and 

 covered v;ith larger and fev;er pustules than occur on those of T, 

 ScV'antesii, there being about 6 large and 30 smB.ller pustules.

South-iA'est Africa* On an undulated plain in the vicinity of 

 'Varmbad; ^chlechter, Winter, and the description of it is not very 

 satisfactorj'", but it certainly seems to differ from V. Schv/antesii 

 by having fewer of the larger rustules on the leaf. In the lesf seen 

 there are only tv/o rosw of them on the upper side of the leaf, 

 and they are rather larger and seem slightly different in microscop- 

 ic structure ffom those of V. ochTvantesii . ^^e colouring of the 

 leaves is described as brovmish-grey-green, shading into dull purple 

 as the base, v?ith pallid pustules at the apex. A variety is des- 

 cribed as "var. alboviridis, Dint.," which only differs by having 

 the leaves greenish-vrhite as in V. Schvrantesii. But as V. Schwan- 

 tesii varies from ivory-white to green, with or without a purplish 

 tinge on the very same plant, in different purplish year, according 

 to the amount of sunshine and v/ater it has received. I consider 

 that the varietal name is superfluous. Although the discovery of 

 this plant is claimed b y Professor Winter, I have been credibly 

 informed that it v;as discovered by Mr. -^chlechter before ^inter 

 had arrived at ^'fermbad.

TITAITOPSIS, Schvvant. 



13 stemless perennials, v/ith a fleshy root-stock,. Leaves oppo- 

 site, crowded in dense rosettes, spathulate, covered v/ith raised, 

 v/hitish or tinted '^ustules, formed of cells f lied v/ith lime. 

 Flov/ers solitary, subsessile or pedicellate, expanding in the after- 

 noon. (See T^ig". 107, p. 878, Vol. LlCCCVIIl). Calyx subequelly 

 6-lobed dov,Ti to its union with the ovary, and the lobes pustulate 

 like the leaves, 4 of them v/ith membranous margins, tetasl free, 

 in one series, lineer. S+prpens numerous, collected into e cone, 

 filaments beprded at the base. Glands in a crenulate ring, -^tig- 

 mas 5 or 6, or 10 in one species, filiform. Ovary inferior, flat- 

 tish or conical at the top, 5 or 6-celled; placentas on the outer 

 wall of the cells. Capsule broadly end shortly obconic, flat on 

 the top, v/ith 5 or 6, or in one species 10, valves and cells; 

 valves as broad as long; expanding-keels rather stout and sub- 

 contiguous at theip base half then v/idely diverging, minutely toothed 

 on the inner edge, excurrent at th"; margin about half-way up the 

 valve, and ending in an av/n reaching to the tip of the vslve, and 

 with 8 membranous margin to the part belov/ the av;n; cells roofed 

 v/ith membranous, semi-transparent cell-v/ings, and v/ithout a placen-
