APETALOUS EXOGENS 



SUm 2 or 3 to 8 or 10 feet high, branched ; branches finally smooth. Leaves % 

 an inch to 2% inches long, often cuneate-obovate and very entire; petioles about 

 a line in length. Pistillate aments elongating, 1 to finally 2% inches long; coma 

 long and copious. 

 Hob. Woodlands; slaty hills: not common. Fl. April. Fr. May. 



Obs. This seems to be very nearly allied to S. eriocephala, of 

 MICHAUX. My specimens (which are imperfect) have also some 

 resemblance to S. rostrata, of RICHARDSON.

 finely and evenly serrate, silky glaucous-gray beneath, drying black, 



S. NOricea, Marshall. Leaves lanceolate, acuminate; pistil-

 SILKY SALIX. 



Stem 4 to 8 or 10 feet high, with slender greenish-brown branches which aw 

 cinereous-pubescent when young, and brittle at base. Leaves 2 to 4 inches long; 

 petioles 2 lines to half an inch in length. Pistillate aments % to \% inches long. 

 Staminate aments about half an inch long ; anthers greenish-brown. 

 Hob. Low grounds; swampy thickets: frequent. Fl. April. Fr. May. 



Obs. Specimens of this were made to represent two species in the

5. S. pet i olaris? Smith. Leaves lanceolate, acute, smooth 

 above, slightly silky beneath, finally smooth; pistillate aments 

 ovoid- cylindric, loosely flowered ; ovary oblong, silky. 

 PETIOLED SALIX. 



Stem 4 to 6 feet high. Leaves 2 to 3% inches long; petioles % to % an inch in 

 length. Pistillate aments about an inch long* 

 Hob. Low grounds; margins of swamps. Fl. April. Fr. May. 



Obs. This was collected on the East border of my farm, in West- 

 Chester, in 1843, and I have not attended to it sufficiently to 

 ascertain if it be distinct from the preceding. 



g 2. Aments sometimes precocious, often coaetaneous, lateral, with 4 or 5 leafy bracts 

 at base; ovary sessile, usually smooth (minutely granular, under a lens), some- 

 times pubescent. 



6. S. cordata, var. myricoides, Carey, in Gr. Man. Leaves lan-
