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

 in future. The learned inquirer will find the synonyms of .S. 

 fragilis obscurely implicated in the history of these species ; yet 

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

 qualities. Haller's S . persicce folio aurlculato, p. I.jI of his first 

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

 though quoted in Fl. Suec. ed. 2. 340, for amygdalina ; and it 

 appears by the description of Halier that he had the fragilis 

 originally before him. In his second edition, under /z. 1636, 

 the description is altered, and rather accords with amygdalina.

Tree. June, July. 



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 taj)er point j 

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

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

 rich, shining green ; under j)aler, and more oj)aque ; their edges 

 finely and copiously crenate throughout, discharging a yellow 

 resin, whence the scent originates. This resin, as Linnieus 

 observes, stains paper between wliicli the leaves are pressed, 

 with rows of ))ermanently yellow dots. About the top of each 

 footstalk, in front, are sever.d glands, likewise resinous. Cat- 

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

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

 oblong, obtuse, hairy scales, half the length of their 5 or (5, 

 sometimes 8 or 9, filaments, which are more or less densely
