A. ungulifolia, Masters in Journ. Linn. Soc. XIV. 494 (1875); Bot. Mag. 
t. 7424 is a handsome species of Borneo cultivated in the Singapore Bot. 
Garden. In Journ. Str. Br. R. As. Soc. (1900) 126, Mr. Ridley includes «A. 
unguliflora, Mast.’’ as ‘‘ local in long wet grass’’ at Singapore. His specimen 
from Jurong is in the Kew Herbarium, but in the doubt whether it is not 
merely a garden escape, I prefer not to include it among wild Peninsular 
species. It is also found in Sumatra.
