peduncles ; the upper flowers (as in most of this section) expanding first : scales of the sterile 

 aments much shorter than the woolly hairs that cover them. Ovaries covered with white 

 wool, somewhat recurved, much longer than the scales : styles about one-fourth the length of 

 the ovary. 



Western part of the State (Dr. Knieskern). Michaux's name for this willow must yield 

 to that of Willdenow, as S. incana of Schrank is an older species. I have what appears to 

 be a variety of S. Candida, collected by Dr. Sartwell near Penn-Yan, probably in a shady 

 place. The leaves are pubescent and of a dull grayish green color underneath ; the stipules 

 are larger, obliquely ovate, with a short acumination ; but in other respects the plants are 

 alike. 



2. Salix Muhlenbergiana, Barratt. Muhlenberg's Willow. 



Leaves obovate-lanceolate, entire or remotely and obscurely denticulate, acute or slightly 

 acuminate, even, smoothish above, grayish -tomentose underneath ; stipules semiovate or 

 lunate, half the length of the petiole ; aments ovoid-cylindrical, densely flowered ; scales 

 ovate, obtuse, blackish, villous ; ovary lanceolate, with a long slender beak ; lobes of the 

 stigma 2-cleft. — Barratt, Sal. Amer. no. 1 (not of Willd.). S. conifera, Muhl. in neue Berl.

 Darlingt. fl. Cest. p. 558 (not of Wang.). 



A shrub 4 - 8 (or sometimes as much as 10) feet high ; the branches brittle ; the young 

 twigs clothed with a close grayish pubescence, and often bearing small cones. Leaves 2-5 

 inches long and from three-fourths of an inch to more than an inch in diameter, prominently 

 veined and densely tomentose underneath, acute at the base ; the margin usually entire, but 

 often somewhat waved or marked with a few obscure teeth, smooth and shining above : 

 stipules acuminate. Buds dark brown. Sterile aments about three-fourths of an inch long ; 

 the upper flowers expanding first. Scales distinctly seen through the silky hairs that clothe 

 them. Torus purple. Filaments white : anthers yellow. Fertile aments finally more than 

 an inch long. Capsules spreading ; their pedicels shorter than the scales, tapering into a 

 long slender beak. 



Borders of woods, and in copses ; frequent. Fl. April. Fr. May. I have specimens of 

 a variety of this species with obtuse and even emarginate leaves, collected by Dr. Sartwell 

 near Penn-Yan. Dr. Barratt thinks S. recurvata of Pursh is only a narrow-leaved form of 

 this species. 



3. Salix tristis, Ait. (Plate CXVIII.) Dwarf Downy Willow. 



Leaves narrowly cuneate-oblanceolate, acute at each end, strongly veined underneath and 

 grayish-pubescent both sides or finally smoothish above , the margin nearly or quite entire, 

 revolute ; stipules none or caducous ; aments globose -ovoid ; scales roundish -obovate ; 

 stigmas 2-lobed ; capsules on short pedicels, with a long beak. — Ait. Kew. (ed. 1.) 3. p. 393 ;
