OuDKK XCIII. SALICACEiE. 



Trees or shrubs, with alternate simi)le leaves, scaly and deciduous or leafy and 

 persistent stipules, and diujcious flowers in terminal aments, each flower subtended 

 by a membranous bract, without j)erianth ; stamens '1 to several, central or scat- 

 tered upon a glandular disk ; ovary 1-celled, with 2 often sessile stigmas, and 2 

 parietal many-ovuled ])lacent;e ; capsule 2-valved, with munerous erect minute 

 comose seeds ; albumen none ; radicle inferior. 



Only the two following genera, belonging to the northern lieniisiihere, usually i>referring wet or 

 danij) jilaces. The wood is light and soft, and the baik contains bitter iirinViiiKs (.sv^//t//( and 

 pjpiilin) used in the cure of interniittents as substitutes for (|uinine. The slender liexihle twigs 

 of some species of Sali.v am in general use for liaskctniaking, and several are extenbivciy culti- 

 vated for ornament ; of ra})id growth, and ready propagation b}' means of cuttings. 



1. Sallx. Bracts (scales) entire. Flowers witli small glands ; disks none. Stamens few. 



Stigmas short. Buds with a single scale. 



2. Populus. Biacts lacerate. Flowers with a broad or cui)shaped disk. Stamens numerous. 



Stigmas elongated. Buds scaly.

 mostly long and pointed, feather-veined. — Andersson, in DC. I'rodr. xvi^. 191. 



A large and diflicult genus of about 160 .species, often very variable ; about 60 si)ecies are 

 North American, the remainder belonging to Kuropo and e.xtra-tropical Asia, excepting lialf a 

 dozen found in S. America and S. Africa.
