122 . AET. I. B. HAYATA : 



mentioned shows me clearly that it is exactly the same as the 

 specimen in Heney's collection, (which lacks flowers), bnt qnite 

 different from Hookee's plant. I have also fonnd that my 

 flowering specimen accords very well with Gynostemma integrifoliola 

 CoGN., the specimen of which lacks frnit. In the original de- 

 scription of CoGNiAUx, there is mentioned " frnctns fuscus glaber 

 vel leviter pnbernlns, 7-8 mill., crassns." The description must, 

 I infer, have drawn up from a praemature fruit, as there is given 

 no account about seeds. The fruit of this species are, as is seen 

 in my specimen, as long as 4 cm. and has numerous winged 

 seeds. The Gynostemma of Cogniaux, as far as my coUections 

 with flowers and fruit are concerned, does not accord with the 

 general characters of Gynostemma, but quite agrees with those 

 of Alsomitra. My plant and also Cogniaux's plant, therefore, 

 should be referred to the latter genus. Accordingly, the new 

 combination, A. integrifoliola Hayata is much to be desired for 

 the present plant. It comes very near to A. clavigera Hook, f., 

 but diflers from it in having much smaller pod which is only 

 half the size of those of the latter plant, and also in having 

 much smaller seeds with thin wings, which are bluntly and ob- 

 scurely indented on the margin. The seeds of Hookee's plant are 

 much larger and have acutely, clearly and grossly indented wings.
