The Indian and Indo-Malayan species of the Qandarum 

 section of Amorphophallus have yet to be studied with a view 

 of defining the species, if indeed there is more than one. 

 The figures of the type of the section, A. campanula f if s, 

 Blume, the Aram campanulatum of Roxburgh, differ greatly 

 from one another ; and the earliest of them, that of 

 Rumphius, is useless for purposes of identification. Nor is 

 the figure of Roxburgh, in his Coromandel plants, much 

 better, whilst that in this Magazine (t. 2812) i3 very unlike 

 all the rest. The magnificent plate in Blume* a " Rumphia " 

 (t. 32, S3), drawn from Javanese individuals, leaves nothing 

 to be desired, and answers to my recollection of the Bengal 

 plant. It differs from that here figured in the narrower 

 leaflets, and the absence of the large pale spots on the 

 spathe, as also in the enormous size of the spathe, which 

 latter, however, is not a character of any importance. The 

 figure that approaches nearest to A. virosus is that of Arum 

 Uumphii of Gaudichaud (Botany of Freycinet's Voyage, 

 p. 127, t. 34), to which that author refers Arum campanula- 

 turn, Roxb., as a synonym, for it has the large white spots on 

 the spathe. It was found in Timor, and it is upon a Timor 

 plant that Blume founded the genus Amorphophallus, 

 supposing it to be the same with Roxburgh's Arum cam-
