DIOECIA HEXANDRIA. 
Stem twining, terete, prickly. Leaves on petioles 6 — 8 lines long, pan- 
duriform, acute, sometimes almost hastate, with the lobes round, lucid, some- 
what rigid, with 3 distinct and 2 or 4 obscure nerves. Flowers in axillary 
umbels, common peduncle about an inch long, twice as long as the pedicels. 
Ferry spherical, black. 
I feel some hesitation in referring to this species the S. Tamnifolia of Mi- 
ehaux, (2. p. 238.) The plant I am describing is certainly not herbaceous. 
Grows often in dry soils.
