122 : ART. I.—B. HAYATA: 
mentioned shows me clearly: that it is exactly the same as the 
specimen in Henry’s collection, (which lacks flowers), but quite 
different from Hooxerr’s plant. I have also found that my 
flowering specimen accords very well with Gynostemma integrifoliola 
Coan., the specimen of which lacks fruit. In the original de- 
scription of Coaniavx, there is mentioned “fructus fuscus glaber 
vel leviter puberulus, 7-8 mill., crassus.” The description must, 
I infer, have drawn up from a premature fruit, as there is given 
no account about seeds. The fruit of this species are, aS is seen 
in my specimen, as long as 4cm. and has numerous winged 
seeds. The Gynostemma of Coaniavx, as far as my collections 
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 Coaniavx’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 Hoox. f., 
but differs 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 Hooxer’s plant are 
much larger and have acutely, clearly and grossly indented wings.
