broad, bright, very shining leaves, find its broad sterile catkins, with 

 numerous crowded yellow stam. Smith says that the small yellow 

 gliinds upon the footstalks of the leaves cause the agreeable fra- 

 grance of this plant.

 obovate acute creiiato.-serrate glaucous and often downy be-

Leaves dark green, turning black when dry, very variable in size, but 

 always more or. less elliptical or obovate, veiny. Catkins rather 

 short. Germens long, extremely silky. .Scf//c.s- brownish or almost 

 black at the tips. "l have some plants from Switzerland whose 

 leaves are quite silky beneath, and a series of specimens gradually 

 less so, till they have the common nearly glabrous appearance. 



14. S. bkolor (sldning'dark green I'Viitow), " leaves elliptical 

 acute denticulato-serrate smoothisb glaucous beneath, ger- 

 mens pedicellate lanceolate silky," Sm. E. B. t. 1S06.

I have never seen this species ; but the characters do not appear at 

 all to distinguish it from the' hist. — " Grows in an upright wand- 

 like form, with dark mahogany-coloured stems," Sm. Germens and 

 scfl/M, according to the fig. as above quoted, exactly as in S. nigricans. 



15. S. pet'wlans {dark lo7ig- leaved Willotc), leaves lanceolate 

 serrated glabrous glaucous and ofteu silky beneath, " germens 

 pedicellate ovate silkv, stigmas sessile 2-lobed," Sm. E. B.

Of this I am unacquainted with the ge.mens, which, according to 

 Smith, are much shorter than in the two last species, while at the 

 same time the leaves are longer and truly lanceolate : — they, how- 

 ever, turn almost black in drying. 



16. S. radkans {rooling-hraiiched Willow), leaves obovato- or 

 elliptico-lanceolate with often wavy serratures glabrous glau- 

 cous beneath, germens lanceolate pedicellate very silky as well 

 as the scales, style elongated, stigma sentire or bitid. S. ra- 

 dkans, Sm. Fl.'Brlt.p. 1053. S.pliylkiJ'olia, E.B. t. 1958;

My spe'cimens are from Sir James Smith, but they do not at ;ill accord 

 'in the germens with the .S. plnjlicifolia of \\'ahl., which that author 

 consideis to be tlie same as Linnteus's. He describes and iigures 

 them as subulate and glabrous, and expressly says he never knew 

 Jhem to be otherwise. Unfortunately Linnaeus himself says nothing
