distinguished them, by their leaves, so that no doubt can arise 

 in future, Tlie learned inquirer will find the synonyms of ^. 

 fragilis obscurely implicated in the history of tliose species ; vet 

 nothing can be much less like them in habit, characters, or 

 qualities. Haller's 5, pcrsiar folio auriculato, p.'15 1 of his first 

 edition, is marked S. fragilis in that book by Linnreus, himself, 

 though quoted in Fl. Suec. ed. 2. 316, for owi/mlaliiia ; and it 

 appears by the description of Haller that he had the tragilis 

 originally before him. In his second edition, under ii. 1(536, 

 the description is altered, and rather accords with amygdalina.

Tree. June, Jiilij. 



A handsome upright tree, about 15 or 20 feet high, exhaling a 

 fragrant bay-like scent from the resinous notches of its leaves, 

 as well as from the barren catkins. The branches are smooth 

 and shining. Leaves on stout, rather short, footstalks, with 

 very small stipulas, or none at all, ovate, with a taper point ; 

 their length 2 or 3 inches ; breadth an inch, or inch and half j 

 both sides finely veined, perfectly smooth ; the upper of a full, 

 rich, shining green ; under paler, and more opaque ; their edges 

 finely and copiously crenate throughout, discharging a yellow 

 resin, whence the scent originates. Tliis resin, as Linnivus 

 ob.serves, stains paper between which the leaves arc pressed, 

 with rows of permanently yellow dots. About the top of each 

 footstalk, in front, are several glands, likewise resinous. Cat- 

 kins solitary, at the ends of leafy shoots of the present year, as 

 in other species ; the barren ones large, dense, yellow, with 

 oblong, ob'.use, hairy scales, half the length oi' their 5 or 6, 

 sometimes 8 or 9, filamuits, which are inoie or less densely
