A. monspessulanum. — A native of S. 

 Europe 10-20 ft. high, with heart-shaped, 

 3-lobed leaves; lobes almost or quite 

 eqvial, entire. 



Culture Ac. as above, p. 813. 



A. montanum {A. spicatvim). — A Ca- 

 nadian tree 18 ft. high, with 3-5-lobed 

 leaves, unequally and coarsely serrated. 



Culture Sc. as above, p. 313. 



A. Negundo {N. fraxinifolium ; 

 Negundo aceroides). — Box Elder ; Asli- 

 leafed Maple. — A very ornamental tree, 

 native of N. America, where it grows 

 40 ft. high. Leaves pinnate, with 3-5 

 opposite coarsely and deeply toothed 

 leaflets, the odd one at the apex usually 

 3-lobed. 



There are several varieties, the best 

 being crispum, with variously cut and 

 curled leaves ; laciniatum, with foliage 

 still more deeply cut ; and variegatwm, a 

 handsome variegated form better known 

 than any of the others. It is usually 

 budded on the green variety, and grown 

 either as a bush or a standard. "When 

 not overplanted to the exclusion of other 

 choice trees the Box Elder and its varieties 

 make very beautiful groups in large gar- 

 dens, parks &c.

 3-foUolate leaves, and large fruits.

A. opulifoliutn [A. Opahis). — A native 

 of France 8 ft. high, with heart-shaped, 

 5-lobed, coarsely toothed leaves, like those 

 of the Guelder Bose {Vihumuni Opulus). 

 The variety ohtusatum is larger and 

 stronger, with dark green leaves covered 

 with a white or rusty down beneath.

A. palmatum {A. polymorphum ; A. 

 dissectum ; A. septemlohum) . — A hand- 

 some Japanese species about 20 ft. high 

 in a wild state. Leaves palmately 5-7- 

 lobed ; lobes oblong, pointed, serrated. 



This is the type of most of the 



elegant beautifully coloured varieties in 

 cultivation. Although no hard and fast 

 line can be drawn between the various 

 sections, it has however been found more 

 or less convenient to arrange the various 

 {orms oi A. pahnatum vinder three heads 

 as follows : 



1. The Palmatum Group proper. — The 

 plants in this group are recognised by the 

 leaves generally having 5 deeply cut lobes. 

 There are many forms, but the following 

 are among the most ornamental : — aureum, 

 a strong-growing form with long-stalked 

 rather large leaves, light green and 

 yellowish when young, but assuming 

 beautiful gold and orange-scarlet tints in 

 autumn; albo-marginatrim, the green 

 leaves of which are edged with white ; 

 crispum, a very distinct form with green 

 red-stalked leaves, rolled up at the edges. 

 The habit is also quite distinct, somewhat 

 resembling that of a miniature Lombardy 

 Poplar ; linearilobum, a form with 

 narrow, slightly toothed or quite entire 

 lobes, cut to very near the base pf the 

 leaves, which when young are red, as are 

 also the shoots, but become green with 

 age ; there is a sub-form of linearilohum 

 called atropurpureum, which differs in 

 having deep bronzy purple leaves ; minor 

 has smaller leaves than the typical palma- 

 tum, they are at first green but assume 

 a bronzy tint with age ; roseo -margina- 

 tum has green leaves edged with rose ; 

 and Shihara Jama has finely serrated 

 pale-green foliage suffused with red and 

 blotched with dark olive-green. 



2. The Septemlobum Group. — The 

 plants in this group are distinguished by 

 the leaves being divided into 7-9 overlap- 

 ping lobes, generally larger than those in 

 the palmatum group. Among the many 

 forms in this section may be mentioned : — 

 atropwrpureum, with bold dark purple 

 foliage ; bicolor, an attractive form ren- 

 dered remarkable by the large carmine 

 blotches on the leaf-lobes, one half of 

 which is often of a very brilliant red; 

 elegans has narrower and more deeply 

 cut lobes than the typical septemlohum, 

 which is a free-growing variety with pretty 

 green leaves. They are of a delicate light 

 green, flushed with red when young, but 

 occasionally tinted with bronze ; the sub- 

 variety, elegans purpureum, is similar in 

 form but of a much deeper bronzy-pmrple 

 tint ; flavescens has the young shoots and 

 leaves more or less of a yellowish tint ; 

 latifolium atropurpureum, has beautiful
