638 CXLI. SALICINE^E. (J. D. Hooker.) \_Populus. 



The Lombardy Poplar, a pyramidal form of the Black Italian (P. nigra, L., var. 

 pyramidalis, Spach, P.fastigiata, Desf.), is cultivated here and there in the N.W. 

 Himalaya, from Simla westward, and in Western Tibet up to 12,500 feet. Griffith 

 considered it to be wild in Affghanistan. The common spreading form is wild in 

 Western Asia and Central Europe. See Brand. For. Fl. 472, and Koyle 111. 344.

Inner ranges of the N.W. HIMALAYA; from Kunawur, alt. 8-13,000 ft., west- 

 wards, and in WESTERN TIBET, up to 14,000 ft., wild and planted. DISTRIB. Central

Along the Indus Valley, in SCIND, the PANJAB, and WESTEEN TIBET, where it 

 ascends to 13,500ft., and planted in the N.W. Provinces. DISTKIB. Western and 

 Central Asia, and westward to Syria and Egypt. 



A tree, 40-50 ft., trunk attaining 8 ft. in girth. Leaves of young shoots 3-6 in. 

 long and broad linear, or oblong entire and shortly petioled ; of older parts 2-3 in., 

 ovate, oblong, rhombic, or orbicular, more or less lobed or cut, base cuneate rounded 

 or cordate, 3-5-nerved ; petiole 1-2 in. Catkins lax-fld. ; male fl., bracts oblanceo- 

 late, incised; ditk orbicular, 8 -cleft ; stamens 812; fern, fl., disk tubular, 812- 

 cleft, membranous, caducous. Capsule large, | in., turgidly lanceolate. From 

 Griffith's plate this is certainly his Aflghan BalsamiJJora deltoides (a " nom de 

 plume" which he never would have published), but I am puzzled by his description 

 of the buds as being gummy, and suspect he had P. balsamifera in his mind, a species 

 he also collected in Affghanistan. 



4. P. alba. Linn. Sp. PI. 1034 ; leaf-buds shoots and leaves beneath 

 white with cottony tomentum, leaves oblong-ovate or broadly ovale or
