50. Cucumis integrifolius, Roxb., (Fl., Ill, 724)) is Gymno- 

 petalum integrifolimn. 1 refer this species to Gymnopetalum, but as 

 the petals are sometimes found jagged, it might also belong 

 to a section of Trichosanthes which I call Pseudo- Trichosanthes. This 

 section comprises the species of Trichosanthes with dioecious, solitary 

 flowers, the females, having them on very short peduncles, or almost 

 sessile • while the males are long and slender. The difference of 

 Trichosanthes and Gymnopetalum appears to rest almost solely in the 

 fringed or not fringed petals, a character to which hardly a generic 

 value can be attached. 



51. Muckia scabrella, Arn., must be changed into 11. Mailer as- 

 patana, (Cucumis Maderaspatana, L. s sp. pi. 1438 — non Roxb.). 



52. Alsomitra heterosperma, Rooin. (Syn. monog., II, 118) is 

 evidently a Gomphogyne, (= Zanonia heterosperma, Wall., in Miq. Fl. 

 Ind. Bat., 1-1, 683).
