CRASSULACEZ. V. CRASSULA. 
and naked ; leaves connate, triquetrous, entire, spreading, gla- 
brous ; corymb compound. h. D. G. Native of the Cape of 
Good Hope. This plant is omitted in Thunberg’s flora, cap. and 
prod. and is therefore doubtful. 
Ascending Crassula. Pl. decumbent. 
50 C.? a'rBa (Forsk. descr. 60. but not of Hortul.) stem sim- 
ple; leaves opposite, crowded, sheathing, lanceolate, cartilagi- 
nously ciliated; peduncles dichotomous; flowers corymbose.— 
Native of Arabia, on the mountains of Hadie and Boka. Flowers 
white, 5-parted. 
White-flowered Crassula. Pl. 4 foot. 
51 C.? xingota'ta (D. C. prod. 3. p. 390.) stem herbace- 
ous; leaves cordate, sessile; peduncles nearly terminal, axil- 
lary, approximate, umbel-formed. ¢.D.G. Native of the Cape 
of Good Hope. Sims, bot. mag. 1765. Flowers yellow. Mr. 
Haworth has placed this species between C. retrofléxa and C. 
centauriotdes; but C. retrofléca is now referrible to Gram- 
manthes, and therefore this species is probably a species of 
that genus. 
Lined-leaved Crassula. Fl. June, Aug. Clt. 1774. Pl. 4 ft. 
52 C.? Acarpura‘na (Schultes, syst. 6. p. 718.) stem suffru- 
tescent, twisted, branched; branches naked; radical leaves 
ovate, imbricated ; cauline ones remote, alternate. h. D. G. 
Native of the south of Spain. According to the description this 
is a species of Sédum or Sempervivum.

plants, they are probably species of Sedum.

N. B. Plants formerly included in the genus Crássula, but are 
now to be excluded from the order. 
1 C.? anrernirdzia (Lin. hort. cliff. p. 497. according to the 
figure in Burm. afr. p. 58. t. 24. f. 1.) is probably a species of 
Borraginea, and perhaps B. ciliata. 
2 C.? pmnna‘ra (Lour. coch. p. 185.) is a plant far separated 
from Créssula, and most probably belonging to the order Tere- 
binthacee. C. pinnata of Dum. Cours. is a species of Bryo- 
phýllum or Kalanchde. The C. pinata of Lin. fil. suppl. 191. 
18 probably the same plant as Loureiro’s. 
Cult. Créssula is an extensive genus of rather ornamental 
plants, and some of which are rather grotesque. A mixture of 
loam, sand, and brick rubbish, is the best soil for them. Cuttings 
Toot very readily if dried for a few days, after being cut off from 
the plants before being planted. The seeds of the annual species 
should be sown in pots, and when the plants have grown a little 
may be separated, and planted into other pots. All the species 
‘outside. —Herbaceous half naked plants.
