31. Cycurs. 
This genus, established by Dr. Arnott, was confounded with 
Clypea and Stephania, until I first pointed out the lines of de- 
marcation between them. It is easily distinguished from them 
by its habit, another kind of inflorescence, by having a gamo- 
sepalous calyx, a turbinately campanular corolla, both of them 
often toothed or cut into deeply laciniated segments, and by 
having a very different putamen. The authors of the ‘Flora 
Indica,’ in acknowledging the validity of Cyclea, rightly united 
my genus Rhaptomeris with it: m the former the calyx and co- 
rolla are tubular, with a four- or five-toothed border; in the 
Jatter the segments are deeper; so that the difference is only one 
of degree, and is consequently of specific rather than of generic 
value. A casual observer may be misled in regard to the num- 
ber of floral parts in the female flower ; for in examining a capi- 
tate head of flowers, a number of persistent scales, varying from 
four to twelve, may be seen sometimes surrounding an ovary ; 
but these extra scales really belong to other abortive flowers 
congregated on the same receptacle. The learned botanists, in 
their work above mentioned (p. 200), describe the female flower 
of Cyclea as having two sepals laterally placed about a solitary 
ovary, without any petal; but this does not correspond with my 
Ann. & Mag. N. Hist. Ser. 3. Vol. xviii. ‘
