to the enlargement of the disks when it also happens. These 

 tendrils possess a threefold power of attachment — by entwining, 

 by the adhesion of disks, and of the cellular layer. This, I believe, 



is not described of any other plant. 



The specimen from which these tubers and tendrils have been 

 taken is of singular and striking interest in the Victoria house at 



a o 



Kew; and especially is this so during summer, The ternate 

 leaves are of elegant outline, shining on the upper surface ; and 

 the square stems are adorned on each angle by a broad wavy and 

 ciliated wing. These beautiful features, however, might easily 

 pass unnoticed from the height at which the stems grow ; but no 

 observer, however casual his examination, can fail to notice the 

 large number of stout roots, which, springing from each node, 

 grow down to the water, and as it were form a curtain along the 

 course of the stems above. In summer, when growing, these 

 roots are of beautiful crimson colour. The cluster of four roots 

 exhibited grew from a single node ; they are more than Hi f ee * 

 in length, and no doubt would have been much longer had they 

 been able or required to grow further.

Note on Gardenia turgida, Eoxb. 



By C. B. Clakj/e, M.A., F.L.S. 



[Eead December 5, 1878.] 



The genus Gardenia contains several Indian species with large 

 sweet-scented flowers, which are included by Sir J. D. Hooker 

 in his subgenus Eu- Gardenia. These have (so far as is known) 

 hermaphrodite flowers ; the calyx-limb is usually produced above 

 the ovary and funnel-shaped ; and the nearly allied Indian 

 species are distinguished mainly by the calyx-teeth, which are 

 lanceolate, \- J in. long in G. lucida and G. latifolia, but in G. 

 tubifera and G. speciosa. In the parallel genus Bandia the 

 calyx-teeth are in like manner in some species minute, in others 

 £-1 in. long.
