103 



and naked ; leaves connate, triquetrous, entire, spreading, gla- 

 brous ; corymb compound. Ij . 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. PI. decumbent. 



50 C. ? A' LEA (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. PI. -| foot. 



51 C.? LINEOLA'TA (D. C. prod. 3. p. 590.) 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. retroflexa and C. 

 centaurioides ; but C. retroflexa is now referrible to Gram- 

 mdnlhes, and therefore this species is probably a species of 

 that genus.

52 C. ? AGARDHIA'NA (Schultes, syst. 6. p. 718.) stem suffru- 

 tescent, twisted, branched ; branches naked ; radical leaves 

 ovate, imbricated ; cauline ones remote, alternate. lj . D. G. 

 Native of the south of Spain. According to the description this 

 is a species of Sedum or Sempervlvum. 



Agardh's Crassula. PL -J foot. 



* * AlternifblicE. The leaves being alternate in the following 

 plants, they are probably species of Sedum. 



53 C. ? MICROCA'RPA (Sibth et Smith, fl. graec. prod. 1. p. 

 217.) leaves oblong ; stem thickened ; capsule angular, dotted, 

 mutic. Q. H. Native of the island of Cyprus, among rocks, 



Small-fruited Crassula. PI. -| foot. 



54 C.? PULCHE'LLA (Ait. hort. kew. ed. 1. vol. 1. p. 392.) 

 leaves ovate-oblong, fleshy, reflexed ; stem herbaceous, dicho- 

 tomous; flowers pedunculate in the forks; peduncles turbinate. 

 O- G. Native of the Cape of Good Hope. Haw. succ. p. 12. 

 Lobes of calyx leaf- formed, spreading, 2 short, and 3 about 

 equal in length to the petals, which are ovate and acute. Flowers 

 pink.

55 C. ? SPA'RSA (Ait. 1. c. p. 395.) stems herbaceous ; leaves 

 alternate, rather spatulate, acute, quite entire ; racemes com- 

 pound. $ . D. G. Native of the Cape of Good Hope. Flowers 

 white? 



Scattered Crassula. Fl. June, July. Clt. 1774. PI. foot. 



N. B. Plants formerly included in the genus Crassula, but are 

 new to be excluded from the order. 



1C.? ALTERNIFOLIA (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. ciliala. 



2 C. ? PINNA'TA (Lour. coch. p. 185.) is a plant far separated 

 from Crassula, and most probably belonging to the order Tere- 

 binthacece. C. pinnitta of Dum. Cours. is a species of Bryo- 

 phijllum or Kalanchbe. The C. pinnata of Lin. fil. suppl. 191. 

 is probably the same plant as Loureiro's. 



Cult. Crassula 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 

 root very readily if dried fora 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 



are well fitted for a dry stove, or to be placed on shelves 

 erected in a green-house. 



VI. PURGO'SIA (from Trvpyoc, pyrgos, a tower ; in reference 

 to the disposition of the clusters of flowers). Haw. in phil. mag.

 shorter than the corolla. Petals 5, imbricating at the base, 

 mucronulate beneath the apex. Stamens 5 ; filaments subulate. 

 Scales 5, emarginate. Carpels 5, flat inside, and gibbous on the 

 outside. Herbaceous half naked plants. Leaves for the most 

 part radical. Inflorescence spicately thyrsoid. Flowers in 

 whorles, almost sessile. The species are probably all biennial.
