Danser, Bull. Jard. Bot. Buitenz. III. 8: 224. /. 14. 1927, accepted the 

 binomial Polygonum hastatotrilobum Meisn. (1865) for this species, which 

 Steward, op. cit. 84 places as P. Thunbergii Sieb. & Zucc. var. hastato- 

 trilobum (Meisn.) Maxim. Steward cites Pételot's number, having seen 

 the spécimen in the University of California herbarium.

 Ceylon to Japan, southward te Luzon, but as yet not recorded from the Malay 

 Archipelago. 



The leaves of the cited spécimen are twice as large as Steward admits 

 for Hooker's species, yet I believe that the material is properly placed under 

 Polygonum praetermissum Hook. f.
