lablab Linn., with which species it has nothing in common. 

 Lablab microcarpus DC. apparently supplies the oldest valid 

 specific name for the species, which is here accepted, although 

 unfortunately not an appropriate specific name, as the fruits are 

 by no means "small" in this species. 



The synonymy of the species is rather complicated, and has 

 been discussed by Prain,* who concludes that the name Canavalia 

 obtusifolia DC. is properly applicable to this form with the 

 wide pods and prominent keels or ridges. Canavalia obtusifolia 

 DC. was based on Dolichos obtusifolius Lam., an American plant. 

 Dolichos rotundifolius Vahl was also described from American 

 specimens, and I believe that this name, as well as Canavalia 

 obtusifolia (Lam.) DC, is a synonym of Canavalia lineata 

 (Thunb.) DC. Katu-tjandi Rheede, Hort. Malabar. 8: 83, t. US, 

 included pods of both Canavalia lineata DC. and C. turgida 

 Gr ah. = Canavalia microcarpa (DC.) Merr. Hasskarl, Neue 

 Schliissel (1866) 136, leaves Cacara litorea as a synonym of 

 Lablab vulgaris Savi, which is an entirely wrong disposition of 

 it. The Rumphian figure is very greatly reduced, whence de 

 Candolle's inappropriate specific name.

 along the strand. 



This strand form, apparently always growing on the loose 

 sand of the beach, is not to be confused with Canavalia micro- 

 carpa (DC.) Merr. (C. turgida Grah.), which grows in thickets 

 back of the beach. It is apparently included in the description 

 of Cacara litorea Rumph., but is not the form figured by him; 

 see Canavalia microcarpa (DC.) Merr., page 280.
