3. 'T. subulata, Benth. et Hook. f. Gen. Plant. i. 658. Stem peren- 
nial, somewhat woody at the base, thick, as are also the principal 
branches, 3-6 in. high, ascending or erect, with opposite ascending or 
erect leafy branches. Leaves connate, spreading, 3—4 lines long, sub- 
ulate, mucronate, rigid, somewhat fleshy. Flowers subsessile, minute, 
“‘ereen,” in dense fascicles in the axils of the upper and sometimes of 
all but the lowest, leaves; fascicles much shorter than the leaves ; 
bracts foliaceous. Calyx nearly as long as the petals, segments lan- 
ceolate acute. Petals lanceolate, longer than the stamens.—Thys- 
antha subulata, Hook. Ic. Pl. t. 590. Crassula subulata, Harv. Fl. Cap. 
li. 852.

In most Cape specimens, the stems and leaves are longer, more slender, and more 
ascending than in Tropical African examples. I cannot, however, find any characters 
by which'to separate the above as a species; and some Cape specimens nearly corre- 
spond with it even in these particulars. 
4. T. alsinoides, Hook. f. in Journ. Linn. Soc. vii. 192. Stems de- 
cumbent, branched, leafy, slender, rooting at the nodes. Leaves ovate- 
oblong, subacute, obscurely 3-nerved, about 4 in. long; petioles sheath- 
ing, connate at the base, the lower nearly as long as the leaves, the 
upper much shorter. Flowers axillary, solitary, on slender pedicels 
often longer than the leaves. Calyx-segments lanceolate, acute, equal- 
ling the petals. Seeds oblong, reddish-brown. Flowers “ white, } in. 
in diameter.”
