NOTES ON CRASSULA. 479 



vestita ... ,, 335 Linn. f. Suppl. 188 



The following notes and descriptions of some of the species 

 which have been regarded as obscure are drawn up from the 

 material in the British Museum, which has been collated with 

 Thunberg's descriptions in the ^uva Acta and with Solander's and 

 Dryander's MSS. Where no notes are given, the plant must, so 

 far as we are concerned, remain obscure ; but Thunberg's full 

 descriptions should not be overlooked by future workers at the 

 genus : — 



Cbassula adscendens. DeCandolle (Prodr. iii. 390) notes that 

 this name is not taken up by Thunberg either in his Prodromus or 

 in his Flora Ccipensis, and must therefore remain doubtful. 



C. ALPESTRis. Specimen from Masson in herbarium. Stem 

 stout, erect, branched above, 3-4 in. high. Leaves connate, broad 

 at the base and clasping the stem, ovate, acuminate, concave, 

 entire, closely imbricating. Flowers terminal, capitate. Capitula 

 several, peduncled, and, as Thunberg states, "piso majora." Petals 

 terminating in long channelled points. 



Bockefeld, Boeckland, and Roggefeld (Thunberg). 



Massou's specimen agrees well with Thunberg's figure and 

 description, both of which are cited by Dryander in his determi- 

 nation of Masson's plants in Herb. Banks. C. alpestris Harv. (Fl. 

 Cap. ii. 311), founded on a specimen from Drege labelled ''Crassula 

 alpestris Th. ? a," is an entirely different plant, belonging to the 

 Eu-Crassula section ; if it be not identical with any subsequently 

 desci'ibed species, it may be called C. Harveyi ; it is, as may be 

 inferred from its position in the sequence of species in the Flora, 

 closely allied to C. sarcocaulls E. & Z. 



C. BARBATA. We havc specimens from Masson, identified by 

 Dryander with Thunberg's plant. Harvey cites it from Thunberg's 

 Fl. Gap. 292. 



C. cAPiTELLA. This is placed by Harvey among the species 

 unknown to him ; he misprints the name " capitellata," We have 

 specimens in the herbarium and in spirit, raised in Kew Gardens 

 (1774-75) from seeds from the Cape, and typical for Solander, in 

 Ait. Hort. Kew. i. 394, who cites Thunberg's description. Stem 

 erect, glabrous, terete, about 8-10 in. high, about the thickness of 

 a pen, and above sometimes branched. Leaves connate, lorate- 

 lanceolate, acute, ciliate, longer than the internodes, basal leaves 

 3|— 4 in. long. Flowers verticillate, white, verticels sessile or 

 subscssile, many-flowered, crowded close together above, rather 

 laxer below. Sepals lanceolate, acute, shorter than the petals. 



Seems to be closely allied to C. Turrita Thunberg.
