‘«Tawhiwhi;” Raiatense, teste Solander, “‘ Hoohove,” vel “ Hubue.” 
T take A, Gray’s Karivia Samoensis, var, B, from Viti, to be the same plant which Banks and Solander 
gathered in the Society Islands, which Solander, in his unpublished Prim, Fl. Ins. Pacit., deseribes as Cucumis 
Maderaspatanus?, and for which he quotes Parkinson’s Drawings, t, 111, with his own manuscript name 
attached. Solander describes the female flowers as growing in the same axils as the male, and on isolated, 
thin, and 1-florous peduneles. The fruit he has not seen, nor do his specimens exhibit any trace of either 
female flowers or fruit. The male flowers are racemose, the pedicels being arranged in whorls, which, when 
the racemes are just beginning to blossom, gives them the appearance of small umbels or corymbs, as stated 
by A. Gray. The racemes are either simple or fureate, 4-5 inches long; the corolla cream-coloured. The 
upper surface of the leaves is generally covered with minute white dots, which are noticed by A. Gray, but 
not indicated by the accurate Parkinson, probably they are not so prominent in fresh specimens ; even in 
some of the leaves before me they are scarcely perceptible. Solander says of them, “ Glandulis winutis 
distinetis, m siccis parum incrustatis.” When the female flowers and fruit are better known, it will pro- 
bably turn out that the species now under consideration is not a true Karivia, Bryonia ? (sp. mov. f), 
No. 290 of Guillemin’s list, Tahiti (Bert, et Merenh.), and Bryonia Johnstoni, Cuzent, O’Taiti, p, 232 
(name only), are doubtless identical with this plant.
