I find nothing to distinguish the specimens of the South Sea 

 Islands from C. pubescens, except the smooth fruit; which, in the 

 form collected at the Feejee Islands still shows traces of the pubes- 

 cence that clothes the ovary: the fruit appears to be globular and 

 scarcely an inch in diameter. In the Tahitian form, the fruit is 

 larger, oval, fully an inch and a half long, smooth and even, with no 

 trace of pubescence. The short lobes of the leaves are only minutely 

 denticulate. This would seem to be Forster's Cucumis bicirrha (of 

 which no specimens are known to be extant) ; but the tendrils are all 

 simple.

G. subglabra; caule gracillimo ; foliis pedatim quinquepartitis sen tri- 

 partitis segmentis lateralibus subbilobis, intermedio productiore, omni- 

 bus oblongis margine repandis; cirrhis bifidis ; racemo rnasculo gracili 

 simplicissimo ; pedunculo floris fozminei fructu oblique ovato oligo-

Cyclanthera Matthewsii, Arn. in Hook. Jour. Bot. 3, p. 280, absque char. 



Hab. Peru, in the vicinity of Obrajillo. 



A very slender plant, glabrous, or nearly so : with pedately five- 

 parted leaves, or sometimes only three-parted, with the lateral divisions 

 slightly two-lobed or nearly entire; the segments oblong, obtuse or 

 slightly pointed, about an inch long, with repand or obscurely crenu- 

 late margins; the middle one longer than the others. Te?idrils two- 

 cleft, elongated. Male flowers in a simple and slender raceme, about 

 the length of the leaves; the flowers barely a line in diameter, on 

 pedicels half a line long, which are not clustered. Female flowers 

 solitary in the same axils with the male flowers, on a peduncle of 

 only a line and a half long. Fruit obliquely ovate, 5 or 6 lines long?
