DICOTYLES. 



735. OTAMPLIS Raf. Dioical, perigone 

 Gphyle, Ssepals internal narrower, male fl. 6 sta- 

 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 I'selium of Loureiro 

 another small family of plants, the'PSELIDES 

 distinct by single ovary and the stamens not op- 

 posed to equal petals. Pselium of Lour. Mart. 

 Bosc, Smith, JJecand. &c differs by Perigone 

 with 4 sepals, 6 free stamens in male flowers, 

 stigma 4fid. The Ps. heterophylum is a twin- 

 ing shrub, with alternate entire leaves, growing 

 in Anarn of Asia. Otamplis derives from Ear- 

 ed Vine. 



736. OTAMPLIS VITIFOLIA Raf. stem twining 

 striate. leaves on long petiols palmate or lobed, 

 Snerved, glaucous beneath, base reniform, lobes 

 acuminate entire, ovate in lower leaves, sinusses 

 obtuse ; racemes shorter than petiols subcom- 

 pound. A large herbaceous Vine, leaves quite 

 smooth, lower ample 6 to 8 inches broad, petiols 

 8 to 10 inches long, upper smaller with 3 short 

 lobes, racemes hardly over one inch long, flow- 

 ers small geminate or ternate, whitish, sepals 

 ovatoblong obtuse deciduous, the inner ones 

 smaller and whiter. On Red River in Arkan- 

 zas and Texas. My specimens are marked a 

 N. G. akin to Menispermum in Collins Herba- 

 rium.
