PRACTICAL GUIDE TO GABDEN PLANTS 



CAEYA 



with 5-angled slightly lobed toothed 

 leaves, wedge-shaped at the base, downy 

 beneath. Flowers in May, greenish, 

 succeeded by brownish fruits ripe in 

 October and November. 



This is said to be the largest deciduous 

 tree in the United States, where it abounds 

 on the banks of the great rivers. There 

 is, or was, a specimen in the grounds of 

 Chelsea Hospital, near the bajoks of the 

 Thames, about 115 ft. high, with a trunk 

 5 ft. in diameter. 



Culture (tc. as above. 



P. orientalis (Oriental or Common 

 Plane). — A splendid ornamental shade 

 tree 60-80 ft. high, native of S.E. Europe, 

 Asia Minor &c., and characterised by its 

 shining green leathery pahnately 5-lobed 

 leaves, with lance-shaped coarsely toothed 

 divisions. Flowers in April, greenish- 

 yellow, succeeded by brown prickly 

 roundish fruits, ripe in October, and hang- 

 ing on the tree well into spring and even 

 summer. 



The London Plane tree is a variety 



called acerifoUa, on account of its Maple- 

 like leaves. It is often confused with 

 the American Plane, but may be easily 

 recognised when in fruit by having more 

 than one cluster of fruits hanging on the 

 stalks. The variety cuneata has the 

 leaves distinctly wedge-shaped at the 

 base ; laciniata has them deeply divided ; 

 and va/riegata is a handsome but rather 

 rare form, easily recognised by having 

 its leaves blotched and streaked with 

 white and pale green. 



Culture Sc. as above. The Common 

 Plane is an excellent tree for smoky 

 towns, the soot and grime and dust 

 apparently having no injurious effects on 

 its smooth leathery leaves. Along the 

 Thames Embankment and in the London 

 parks and squares are several fine speci- 

 mens, and there is also one in the centre 

 of Cheapside. On the banks of the 

 Bosphorus there is a specimen believed 

 to be 2000 years old, the trunk being 

 over 140 ft. in circumference at the base, 

 while the branches radiate for a distance 

 of 45 feet. 



CVI. JUGLANDEiE— Walnut Tree Order 



An order of handsome deciduous trees often with a watery or resinous, but 

 not milky, juice. Leaves alternate, often large, oddly pinnate, with entire or 

 serrate feather-veined leaflets, often oblique or sickle-shaped. Stipules none. 

 Flowers small monoecious ; male ones often in loose drooping catkins, with 

 or without a 3-6-lobed perianth ; female ones usually in an erect spike, with 

 a 4:-toothed or lobed perianth adnate to the inferior 1-celled ovary. Stamens 

 3-40, often attached to a linear receptacle or torus. IVait a dry or leathery 

 drupe, rarely a nut, with a strong, bony, 2-valved endocarp — a scientific 

 description of the popular "Walnut. 



CARYA (Hickory). — Agenus of hand- 

 some deciduous Walnut-like trees with 

 oddly pinnate leaves having serrate leaf- 

 lets. The drooping male catkins are clus. 

 tered in each flower, with 3-10 stamens. 

 Female flowers in short terminal spikes, 

 and having a 4-lobed perianth. Dtupe 

 rather dry, ovoid or roundish, splitting 

 into 4 regular valves, and falling away 

 from the smooth endocarp or shell. 



Culture wnd Propagation. — The 

 Hickories are best increased by seeds, 

 which are often planted about 3 in. deep 

 where the trees are intended to grow. 

 Most of the species have long tap roots 

 destitute of fibres, and transplanting is 

 apt to injure them severely. If sown in 



small pots with a tight-fitting ' stopper ' 

 over the hole at the bottom, the tap root 

 wHl be prevented from getting out, and 

 will circle round the sides of the pot 

 instead ; the seedlings could be readily 

 transplanted to their permanent positions 

 afterwards, and this method is preferable 

 to planting the seeds here and there in 

 the open ground. Cuttings of the tips of 

 the growing roots will sometimes root in 

 sandy soU. Grafting and budding when 

 the plants are in a dormant state will also 

 succeed ; but the easiest way is by seed. 



C. alba {Shell-barTc Hickory). — A fine 

 tree 50-70 ft. high, native of the Eastern 

 United States and Canada. Leaves com-
