480 NOTES ON CRASSULA. 



C. CEPHALOPHORA. Specimen in herbarium from Masson, written 

 up by Dryander with reference to Thunberg's paper. Flowering 

 stem terete, erect, thinly grey, subtomentose, 12-18 in. high. 

 Leaves in a basal rosette, lanceolate-oblong, acute or subobtuse, 

 erect or erecto-patent, tomentose, ^-J in. long, entire ; this slightly 

 differs from Thunberg's description, which calls the leaves linear 

 or linear-oblong and obtuse : Harvey has a var. latifolia, to which 

 Masson's specimen should probably be referred. Flowers in lateral, 

 globose, pedunculate heads, peduncles often about | in.|long; at the 

 base of the 2-3 peduncles, springing from the same point on the 

 stem, are 2-3 triangular or oblong tomentose bracts. Diameter 

 of heads of flowers ^-^ in. 



Agrees in every respect with Glohnlea canescens Haworth (Syn. 

 PI. Succ. 65 (1819) ) = Crassula canescens Roem. & Schultes, 

 Systema, vi. 734 (1820) — the name retained by Harvey, which 

 must be replaced by cephalophorn — and with a specimen named by 

 Harvey from Uitenhage, No. 993. 



C. coLUMNARis. Specimens in the herbarium from the Cape 

 (Masson), and in spirit, identified by Dryander with Thunberg's 

 plant. 



C. coRALLiNA. Specimen in herbarium from Masson, named by 

 Solander, and referred by Dryander to Thunberg's description. 

 A dwarf dichotomously branching plant with opposite, sessile, 

 distinct, carnose, entire, punctate leaves, which are 1-2 lines long ; 

 the white pulverulent character of the extremities of the leaves 

 noticed by Thunberg is very apparent. It is not in flower, but is 

 certainly identical with C. dasyphylla Harvey, based upon Drege 

 No. 6885, with which we have compared it. Thunberg's plant 

 was from "campis siccis Hantum inter Daunis et Roggefeldsberg " ; 

 C. dasyphylla Harv. was gathered by Drege "at Wiuterveld between 

 New Year's Fountain and Ezelsfont." 



C. coRDATA. Roemer & Schultes (Syst. Veg. vi. 722) point out 

 quite correctly that Thunberg's plant (which we know only from 

 description) differs from that described in Ait. Hort. Kew. i. 396. 

 They proceed, however, to give Thunberg's species a new name — 

 neglecta, retaining cordata for Alton's plant. This is of course 

 contrary to the law of priority, in accordance with which Thunberg's 

 plant must retain the name cordata, and a new name must be found 

 for the cordata of Alton : this we propose to call Aitoni. The 

 synonymy will be — 



C. CORDATA Thunb. in Nov. Act. vi. 330 (1778) ; Linn. f. Suppl. 

 189 (1781). 

 C. neglecta Roem. & Schultes, I. c. 

 C. Aitoni. 



C. cordata [Dryand. in] Ait. Hort. Kew. i. 396 (1789); Harv. 

 Fl. Cap. ii. 347, et auct. plur., non Thunb. 



C. MOLLIS. There is a specimen in the herbarium from Masson, 

 unfortunately without leaves, and there are also rather fragmentary 

 spirit specimens. The inflorescence is paniculate, and at the base
