ia having no indication of pubescence in any part of the plant 
except on the small bracts of the raceme. The leaves are about 
If inch long, 1| inch broad, on a petiole f inch long, inserted 
1-3 lines within the margin of the scarcely appreciable basal 
sinus. The raceme is somewhat flexuose, about 1^-2^ inches 
long, with alternate axils 2 lines apart ; out of each axil there is 
a linear bract 1 line long, two one-tlowered pedicels of equal 
length, and a branchlet somewhat longer, bearing three other 
almost sessile flowers ; the putamen and seed quite conform to 
the characters of the genus. 
32. Peraphora. 
This genus was first proposed by me for a plant originally col- 
lected in Bhootau by GriflSths, which had female flowers and fruit 
only. Since then 1 found that the Cyclea populifolia described 
by Messrs. Hooker and Thomson is the male plant of the same 
species. It diflPers from Cyclea in its habit, its large, coriaceous, 
cordate leaves on a rigid petiole almost palately inserted, its 
dififerent mode of inflorescence, in its floral structure, and in its 
putamen. Although the male flower has a campanula!- calyx, it 
has no petal; the female flower has two comparatively large, 
opposite, sacciform, fleshy sepals, and no petal, and its putamen 
bears no resemblance to that of Cyclea, It is thus certain that, 
with the exception of a campanular calyx in the 6 flower, the floral 
structure in both sexes is totally at variance with the characters 
of the genus to which it has been referred by the authors of the 
‘ Flora Indica.’ In the number of calycine parts it accords with 
Antizoma ; but it differs in having no petals, and in the ganio- 
sepalous calyx of its ^ flower : these differences, together with 
the very dissimilar habits of the plants, will maintain the validity 
of both these genera. The putamen, in its sha]ie and its curved 
spines, resembles that of some species of Stephania, but it differs 
in having an imperforated condyle. 
The generic name, was suggested by the singularly bursiform 
sepals of the female flower.
