posed of 5 finely serrate, more or less 

 oblong or obovate lance-shaped leaflets. 

 Flowers in May, greenish. Fruit globular 

 or depressed, containing a white thin- 

 shelled nut. 



Culture dc. as above. 



C. amara (Bitter Nut ; . Swamp 

 Hickory). — A native of the same region 

 as 0. alba, and growing 60-60 ft. high. 

 Leaves composed of 7-11 more or less 

 oblong lance-shaped leaflets, downy when 

 young. Flowers in April, greenish ; cat- 

 kins in pairs. Fruit roundish, with 6 

 narrow ridges, and containing a round 

 short pointed nut. 



Culture do. as above. 



C. microcarpa. — A beautiful North 

 American tree with leaves usually com- 

 posed of 5more or less broadly oblanceolat e 

 roundly toothed and pointed leaflets 4-6 

 in. or more long, the odd terminal leaflet 

 being larger and broader than the others 

 about 6-8 in. long. In autumn the fpUage 

 of this species, as well as that of the 

 others, assumes a soft yellow tint. It is 

 now regarded as a variety of C. porcina. 



Culture dc. as above. 



C. olivaeformis [Pecan Nut). — This 

 grows with the two preceding species, and 

 attains a height of about 30 ft. Leaves 

 having 13-15 oblong lanee-shaped or 

 sickle-shaped serrate leaflets, gradually 

 tapering to a point. Flowers in April 

 and May, greenish. Nut olive-shaped. 



Culture dc. as above. 



C. porcina (C. glabra). — Pig Nut; 

 Brown Hickory. — ^A fine tree 70-80 ft. 

 high, from E. North America. Leaves 

 with 5-7 oblong or obovate lance-shaped 

 serrate leaflets. Flowers in May, greenish. 

 Nut oblong or oval, with a thick bony 

 shell. 



Culture dc. as above. 



C. tomentosa {Mocker Nut; WMte- 

 heavt Hickory). — A companion of the 

 preceding species in a wild state, often 

 60-70 ft. high. Leaves composed of 7-9 

 obovate or oblong lance-shaped pointed 

 leaflets. Flowers in May, resinous scented, 

 in short catkins. Fruit roundish or ovoid, 

 with a thick hard husk, enclosing a 

 very thick-shelled round brownish nut, 

 4-ridged towards the summit. The variety 

 maxima has fruits as large as an Apple, 

 with an extremely thick husk. 



Culture dc. as above. 



JUGLANS (Walnut), — A genus con- 

 taining 7 or 8 species of trees with an 

 odorous or resinous bark, and large alter- 

 nate oddly pinnate leaves. Male catkins 

 lateral, drooping, the flowers having a 

 5-6-lobed perianth with irregular borders, 

 and 8-40 stamens on a linear torus. 

 Female flowers few, in terminal spikes. 

 Perianth 4-lobed, surrounded by an invo- 

 lucre consisting of bracts and bracteoles 

 adnate to the ovary. Drupe ovoid or 

 globose, with a thick fleshy husk bursting 

 irregularly, and containing a thick hard 

 wrinkled bony-shelled nut, opening by 

 2 valves. 



Culture and Propagation. — Walnuts, 

 apart firom their value as firuit trees, are 

 highly ornamental and suitable for parks 

 and large gardens. They flourish in rich 

 deep soil where the roots can ramble 

 away to moist spots. I know some fine 

 old Walnut trees which flourish in what 

 appears to be the poorest soil, that has 

 never been touched in any way for years, 

 and is simply as hard as a macadam road. 

 Still the plants produce large crops of 

 fruit almost every year, and are in the 

 best of health. Walnut trees are increased 

 in the same way as the Hickory described 

 above, chiefly by sowing the seeds when 

 ripe. 



J. cinerea (Butter Nut). — A native of 

 the United States, 30-60 ft. high. Leaves 

 composed of 15-17 lance-shaped serrate 

 leaflets, rounded at the base and downy 

 beneath. Flowers in spring, greenish. 

 Fruit oblong ovoid taper-pointed, downy 

 and clammy. 



Culture dc. as above. A hybrid be- 

 tween this species and /. regia has been 

 obtained and is known as /. alata. 



J. mandschurica. — A very handsome 

 Walnut tree, native of Amurland. The 

 leaves are over 30 in. long and composed 

 of about 15 lanoe-shaped acute leaflets 

 4-8 in. long, feather-veined and some- 

 what toothed on the margin. The fruits 

 are about the size and shape of a hen's 

 egg, but rather more pointed at the at- 

 tached end. The kernel, although edible, 

 is not so palatable as that of the Common 

 Walnut, but they ripen 2 or 8 weeks 

 earher. 



Culture dc. as above. 



J. nigra.— A tree about 60 ft. high, 

 native of the United States. Leaves 

 having 13-17 heart-shaped tapering ser-
