Petch in Ann. Perad. VII, p. 53 (1919), states that this is only 
known as a Ceylon species from a specimen in Thunberg’s herbarium, 
which is A. macrorrhiza, and that the plant called Rata-ala or Desa- 
ala is a species of Xanthosoma, 
A. macrorrhiza Schott. is stated to have peltate leaves in the FI. 
Brit. Ind. (VI, p. 526) and Wight Ic. t. 797 is quoted; it seems to be 
A. odora in Engler’s sense and is perhaps the plant shown in J.R.H.S. 
LII, f. 2-3 (1927), and in Rep. Miss. B. G. XI, p. 11. 
The leaves of the Ceylon specimens are not peltate, and agree well 
with the A. indica of the Fl. Brit. Ind. (p. 525), as represented by 
Part IV.
