Wight Ic. t. 794. A. macrorrhiza in Engler’s sense (Mon. Phan. p. 502) 
has not got peltate leaves. A. macrorrhiza is restricted to Ceylon by 
Haines (Bot. Bihar and Orissa p. 870) and the name A. odora applied 
to the Indian plant. Fl. Zeyl. no. 327 appears to be the type of Arum 
macrorrhiza Linn. and so the name is rightly applied, though A. indica 
may be a synonym. Bot. Reg. t. 641 has the spathe green within, 
while that of our plant is white within. I suspect that A. indica is the 
cultivated species with spotted petioles.
