and Dryander in the second, and this is true ; but it is also clear 

 that Dryander helped in the former, and Mr. Jackson — see under 

 Comjza (B/ji/pti'ica in the Index Keivensis — recognizes this fact. The 

 relative portions attributable to each may be ascertained by referring 

 to the Solander MSS., and to the plants in the British Museum 

 Herbarium, where, as is known, the types of the llortus Keivensis 

 are preserved. Dryander made numerous additions to Solander's 

 notes, and the plants in the herbarium are often written up by 

 him. Mr. J. J. Bennett's statement in the preface to vol. ii. of 

 Brown's Collected Works seems to give colour to the supposition 

 that Solander was responsible for the first edition * ; but the 

 younger Alton, in the often overlooked postscript at the end of 

 vol. V. of ed. 2 (pp. 531-2), says expressly that Dryander "con- 

 tinued to the son the assistance given to his father during the 

 publication of the former edition of this work." Solander died in 

 1782, and the first edition did not appear until 1789. Mr. Boulger, 

 ia the dictionary of National BiograpJiy, refers to Dryander as the 

 " main author " of this edition. 



The following notes and descriptions are based upon the types 

 preserved in tlie herbarium and in spirit at the British Museum. 

 The names of the species, as well as the numbers which they bear 

 in Alton, are written on the labels of the spirit specimens by 

 Dryander. We have been guided by the Solander MSS. and the 

 labels of the specimens in assigning the species to Solander and 

 Dryander respectively. 



C. ALOoiDEs [Solander in] Alton, Hort. Kew. i. p. 394, No. 17 ! 

 Specimens from Masson in herbarium and from Hort. Kew., 

 where it flowered in 1778, in spirit. The herbarium specimens, 

 named by Solander alooides, were subsequently doubtfully referred 

 by him to orbicularis — a doubt also expressed in his MS. description. 

 Leaves in the herbarium specimen all basal, rosulate, distinct, im- 

 bricating, broadly ovate, fleshy, glabrous, according to Solander 

 covered with minute impressed red dots, about 1-1^ in. long, rather 

 more broad. Peduncle scape-like, leafless (the cultivated specimen 

 has three pairs of ovate stem-leaves), about 4-6 in. ; cymes densely 

 fascicled, as in C. orbicularis, in an interrupted thyrsus ; fascicles 

 7-9 opposite, shortly peduncled. Sepals glabrous, about 1 line 

 long. Petals about tlu'ee times longer than the calyx, "white, 

 virescent below." Filaments white. Anthers subrotund, small. 



Closely allied to C. orbicularis L., but the leaves are broader, 

 and there are more opposite fascicles in the inflorescence. This is 

 placed by Harvey among the species unknown to him. 



Mr. N. E. Brown, in the Kew Bulletin for 1896, p. 161, de- 

 scribed a different species under the name aloides, founded on 

 Eehinann, No. 6375, which, however, had previously been described 

 by Dr. Schinz in Bull. Herb. Boissier, ii. 204, as C. acinaciformis.
