Chenab and in Kunawar it does not ripen its fruit well at an elevation above 

 9500 ft. The wUd Walnut merits cultivation as a forest-tree on account of its 

 timber ; when grown in compact masses it cannot be expected to produce much 

 fruit, but the timber would probably prove one of the most valuable of the 

 leaf-bearing trees of the North-West Himalaya, and it has the advantage of not 

 being too heavy for floating. The tree, however, requires a rich and deep soil, 

 and will probably not prove to be a rapid grower. 



J. nigra, L., the Mack Walnut, sometimes called Black Hickory, of North 

 America, particularly in Ohio and Kentucky, south to Florida and Texas, has 

 serrate, ovate-lanceolate, long-acuminate leaflets, and a spherical incompletely 

 4-ceUed nut. Wood beautifully veined, valued for furniture, heavier than that 

 of J. regia (lighter according to Nordlinger, Techn. Bigensch. d. Holzes, 522). 



J. cinerea, L., the Butter-nut of Canada and the Northern States, has oblong- 

 lanceolate, downy leaflets, an oblong nut, 2-ceUed at the base. 



2. ENGELHABDTIA, Leschenault. 



Resinous trees or large shrubs. Leaves sometimes apparently paripin- 

 nate by the abortion of the terminal leaflet. Male flowers in cylindric 

 lateral catkins. Perianth of 3-6 lobes, adnate to a lateral generally stip- 

 itate often 3-lobed bract. Stamens 4-12, anthers subsessile. Female 

 flowers in long drooping braoteate spikes. Calyx adnate to the ovary 

 with a 4-dentate limb. Petals none. Stigmas 2, sessUe, linear, papillose. 

 Bract cup-shaped, enclosing the flower, limb divided into 4:,unequal seg- 

 ments, the inner rounded, often crenate, the three outer membranous, 

 veined, generally oblong, the middle one longest. Fruit small, enclosed 

 by the enlarged bract ; pericarp thin, firmly adhering to the endocarp.

 rulcli, Pb. ; Mowu, gohar moioa, hodal mowa, Kamaon ; Khusam, Banda. 



A large shrub or moderate - sized tree, the current year's branch lets 

 tomentose or pubescent. Leaves generally approximate near the ends of 

 branches, mostly imparipinnate, leaflets 3-5 pair, nearly opposite or alter- 

 nate, shortly petiolulate, eUiptic-oblong, obtuse or acute, base unequal- 

 sided, subcoriaceous when full-grown, pubescent or tomentose when 

 young, the upper side glabrous when fuU-grown, the under side tomen- 

 tose or with minute round yellowish scales; main lateral nerves 10-15 on 

 either side of midrib, joined by prominent reticulate and intramarginal 

 veins. Male catkins numerous, 3-5 in. long, generally clustered at the 

 base of the female spikes. Bract stipitate, more or less 3-lobed, bearing 

 4-5 oblong obtuse scales, one generally at the base, the others at the top 

 or along the sides of the bract, and 6-8 sessile hispid mucronulate anthers. 

 A tuft of hairs, in the place of a rudimentary ovary, not rarely between 

 the anthers. Female spikes pedunculate, 5-6 in. long, drooping, lax when 

 in flower, cylindric, compact when in fruit, outer bracts in fruit spathulate- 

 oblong, obtuse, the middle one 1-1 1 in. long, the two lateral ones half 

 that length, each with a prominent midrib, and reticulate veins, with 

 minute round scales, glabrous or pubescent, the inner bract irregularly 

 dentate, hispid with long stiff hairs.
