ON SALIX SABLERI, Symo, AKD CAREX FRIGIDA, 

 Alliom, RECENTLY DISCOVERED IN THE HIGHLANDS 

 OF SCOTLAND. 



By J. T. BoswELL Syme, LL.D. 

 Salix Sadleri, Syme. 

 (Tab. 158.)*' 



Stems mostly buried, rooting ; branches very short ascending ap- 

 parently terminating in a peduncle. Leaves few, very shortly stalked, 

 firm, roundish-ovate, rounded or sub-cordate at the base, acute or sub- 

 acute, entire, dark-green, and more or less cottony but not rugose 

 above (the veins not being impressed), ultimately glabrous and green 

 beneath, with the midrib, secondary and tertiary veins prominent be- 

 neath, but the greater number of the ultimate veins conspicuous but 

 not prominent, the interstices sprinkled with minute white dots; 

 stipules absent, but scales sometimes persistent. Cathins opening after the 

 leaf-buds, on rather short leafless peduncles, apparently terminating 

 the branches, slender, oblong-cylindrical, short, many-flowered; 

 catUn-scales oblong-oblanceolate or oblong or narrowly olong, obtuse 

 or sub-obtuse, at length dark brown, tipped with black, with a few 

 woolly hairs on the back, and a dense coma of white silky- woolly 

 hairs at the apex and extending beyond it nearly the length of the 

 scale. Capsule lanceolate-conical, acuminate, glabrous, with a long 

 woolly stalk ; style half as long as the capsule, exceeding the stigmas ; 

 stigmas linear, two-cleft. Toimg branches woolly ; young leaves thickly 

 clothed with long silky woolly hairs beneath, which are sub-persistent 

 on the midrib ; buds finely pubescent, ultimately glabrous. 



Stems very similar to those of Salix herbacea. Branches blackish 

 chestnut, tortuous, with short leafy branches at the end of the 

 previous year's wood, each branch with two or three leaves. Leaves 

 ^ to 1 inch long, exclusive of the petiole, which is about | inch long. 

 Peduncles about i to f inch long, woolly. Catkins produced as in 

 Salix reticulata, ^ to f inch long, with the scales much shorter than 

 the capsules, but the tips of their hairs reaching nearly to their apex. 

 Capsule about ^ inch long, on a stalk about to inch long. Style to 

 to i inch long. 



Similar in habit to Salix reticulata, but the leaves differing in 

 shape and in texture ; the under side especially is strikingly different,
