iLEi. TETRANDRIA. TE TRAGYNIA. 195 



This species differs in some respects from the rest of the 

 genus with which I am acquainted, but perhaps not sufficiently 

 to constitute a new genus. The corolla appears to me to 

 be 4-petalled, and not 4-cleft, as Ilex is stated to be. Jus- 

 9ie Uy however, says, " Corolla 4-partita, seu 4-petala, petalis 

 ungue lato cohserentibus." I have never seen the leaves 

 toothed, as they are represented in Michaux^s figure.

JRoot fibrous (annual, i.. Sec.) Ste?n rooting, branched and 

 spreading, 2 — 4 inches long. Leaves linear-subulate, oppo- 

 site, connate at the base, about the root crowded. Peduncles 

 axillary, solitary, longer than the leaves. Leaves of the calyx 

 spreading, ovate, obtuse. Petals scarcely more than half the 

 length of the calyx, entire, sonnetimes wanting. Capsule 

 longer than the calyx. 



Hab. On the borders of creeks and about springs, among rocks. 

 Near Weehawk, New-Jersey. July. T. In the neighbour- 

 hood of New-Haven, Connecticut j Stockbridge, Massachu- 

 setts ; and about Troy, New-York. Eaton. 



The habitat of this plant differs from the European species, 

 which occurs in dry soils. Jn every other respect they agree 

 precisely. 



2. S. apetala L. : annual ; stem erect, pubescent ; leaves 

 (Cuspidate ; flowers alternate ; petals very minute or 0.
