652 PHANEROGAMIA. 



glabrous or nearly so above, rather softly pubgrutent underneath, the 

 short and fine pubescence at length nearly deciduous, not papillose- 

 scabrous, the margin coarsely and sharply denticulate with mucroni- 

 forrn callous-tipped teeth. Petioles 3 inches long. Tendrils three- 

 cleft. Male and female inflorescence usually from the same axils. 

 Male panicles umbellate (4 or 5 together) at the summit of a deeply 

 grooved long and slender peduncle (of 5 or 7 inches in length), glan- 

 dular-puberulent, as well as the exterior of the flower-buds : the fili- 

 form "pedicels often fascicled, 4 or 5 lines long. Perianth with a turbi- 

 nate tube, five-cleft above the middle, or at length the accrescent and 

 triangular-ovate lobes of the corolla longer than the tube, greenish- 

 white, becoming 5 lines in diameter when expanded ; the calyx-teeth 

 short and subulate. Androecium as in the foregoing species, except 

 that the anthers (either 3 or 5) are themselves more or less syngene- 

 siously united, often somewhat twisted. Fertile flowers not seen. 

 Fruit ovate, b-^-angled, nearly glabrous, wholly unarmed, in an 

 immature state conspicuously beaked, in size and character closely 

 resembling that of the preceding species. The fruits are clustered on 

 the summit of a peduncle which is 2 inches in length. 



Perhaps intermediate states w r ill occur between this and S. pachy- 

 carpu&. Our specimens of the two are not sufficiently complete to 

 remove all doubt. But this would seem to differ specifically in the 

 foliage and inflorescence, notwithstanding the similarity of the fruit.
