025E87B54D4CFFDE4C36FAB239F2A556.taxon	discussion	Note — The shape of the spathe of A. fornicatus and the echinate appendix are unique compared to all species of the genus in Asia. In both characters it shows a remarkable similarity to the West African A. dracontioides (Engl.) N. E. Br. The narrow spathe base and several characters of the female and male zone, and the pistils and anthers are reminiscent of A. hottae Bogner & Hett. from Sabah (eastern Malaysia). The leaf is also similar to that of the latter species, up to the formation of epiphyllar bulbils.	en	Hetterscheid, W. L. A., Medecilo, M. P., Callado, J. R. C., Galloway, A.

025E87B54D4DFFDA4F79F8BC3B46A50D.taxon	discussion	Notes — Amorphophallus rayongii is morphologically very close to A. salmoneus, with which it shares the flattened, verrucate synandrodes between the male and female zone. No other species on the Philippines show this character. It is not a unique character in the genus and is found in quite a number of species from SE Asia, although the verrucate surface of the Philippine species is unique. Amorphophallus salmoneus has been placed in subg. Amorphophallus (Claudel et al. 2017) close to A. dactylifer and A. declinatus both Philippine species. This subclade is part of a larger clade with exclusively insular SE Asian species from Indonesia and East Malaysia. However, all other species with synandrodes similar to those of A. salmoneus and A. rayongii are part of subg. Scutandrium Hett. & Claudel, dominated by mainland SE Asian species. The synandrodes therefore are clearly a parallel expression developed from fertile male flowers in different clades.	en	Hetterscheid, W. L. A., Medecilo, M. P., Callado, J. R. C., Galloway, A.

Note — Of the four, short pedunculate species in the Philippines, A. urceolatus clearly resembles A. yaoi. It differs from the latter by the spadix being approximately as long as the spathe, by the much shorter and broader appendix and the stigma being shallowly or strongly bilobed.	en	Hetterscheid, W. L.
