mens monadelphous at base. Female fl. ovary 
single ovate, stigma sessile large capitate sublo- 
bate. Fruit a single monosperm berry ? Volu « 
ble , leaves alternate , fl. axillary racemose — 
Akin in habit &c to Menispermum, but not 
even of same family, lacking the multiple ber- 
ries; it must form with Pselium of Loureiro

5nerved, glaucous beneath, base reniform, lobes 
acuminate entire, ovate in lower leaves, sinusses
