The specimen: Volkens no. 425 from Yap, Caroline-isl., 

 flow, and fr. on 8-II-1900, we consider as an hybrid between 

 the ,fl-variety of V. Negundo and the a-variety of V. 

 trifolia. It has the habit of V. trifolia, also in the form 

 of ,,the often 1-foliolate leaves, but the terminal ones are 

 usually petioluled and the corolla reaches 0.8—0.9 cM., 

 the calyx 0.2—0.25 cM. It is a very remarkable inter- 

 mediate form, and it may be said emphatically that it 

 seems to be fertile. 



Distribution of the species: E.-Africa. N. -Madagascar, 

 Mauritius, Ceylon, India, Siam, S.-China, Hainan, Formosa, 

 Japan (Hallier), Malay Peninsula! and Archipelago!,' Phi- 

 lippines!, W.-Polynesia ! 



As there is still some confusion in distinguishing V. Negundo 

 and V. trifolia, we enumerate here several distinct differences: 



V. Negundo. V. trifolia. 



1. Leaves 3 — 5-foliolate. 1. Leaves 1—3 foliolate. 



2. Leaflets ovate-lanceolate, 2. Leaflets ovate or broadly 

 often narrowly lanceolate; ovate, sometimes obovate, 

 apex acuminate; margins apex subacute-rounded; 

 sometimes crenate about margins entire; upper side 

 the middle; upper Side glabrous with pubescent
