Salix. SALICACEJE. 205 



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

 anients much sliorter 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 Willdcnow, 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 imderneath ; 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. 

 schrift. 4. p. 240. t. 6./. 9 ; Willd. sp. 4. p. 705 ; Pursh, fl. 2. p. 612, excl. syn. Michx. ; 

 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. rccurvata 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 ;
