THE DICTIONARY OF GARDENING, 



Acer continued. 



America, 1827. A very beautiful species, having pendulous 

 branches clothed with leaves, which change into a bright scarlet 

 colour in the autumn. 



A. crettoum (Cretan), fl. on few-flowered erect corymbs. May. 



% smooth with the wings hardly diverging. I. cuneated at the 

 base, acutely three-lobed at the top. A. 4ft. Levant, 1752. 

 Nearly evergreen. 



A. daBycarpum (thick-fruited).* fl. conglomerate, on short 

 peoS,^p?talous. April. I. truncate at the base, palmately 

 Bve-lobed, with blunt recesses, and unequally and deeply-toothed 

 lobes. A. 40ft. North America, 1725. SYNS. A. eriocarpon, 

 A. tomentontm, A. glaueum, and A. virginianum 



A. Douglasii (Douglas). Synonymous with A. glabrum. 



A. eiiooarpon (bairy-fruited). Synonymous with A. dasy. 

 carpum. 



A. Ginnala (Ginnalian).* fl. on compound, crowded, erect ra- 

 cemes. Amur River. This is generally classed as a variety of 

 A. tartarieum, but its habit is much more graceful, and in this 

 form the leaves are prettily cut and lobed, whilst the leafstalks 

 and midrib are more deeply coloured. 



\glabrum (smooth).* fl. corymbose, on short two-leaved 

 ranchlets, greenish-yellow. June. I. roundish-cordate, deeply 

 three to flve-lobed, or partite ; the lobes bi-serrate, of a light 

 green. A. 15ft. to 30ft. North West America. SYNS. A. Douglaeii, 

 A. tripartitum.

 1826. 



A. japonionm (Japanese).* fl. deep purplish-red, large. April. 

 I. many-lobed, in early spring very Oght green. A. 20ft. Japan, 

 1863. The varieties of this species, although not weU fixed in many 

 cases, rank amongst the most handsome of the deciduous small 

 shrubs grown, but often change in character as they attain any 

 considerable size. Plants from l}ft. to 3ft. high are very useful in 

 cool conservatories, and in the highly kept grounds surrounding 

 the house. 



A. laurifolium (laurel-leaved). Synonymous with A. oblongum. 



A. Lobelll (Lobel's). I. very slightly heart-shaped, irregularly 

 toothed, flve-lobed ; lobes more or less abruptly pointed.

A. p. retlculatum (netted).* I. palmately seyen-lobed ; lobes

A. p. sangulneum (blood-red).* I. deeply flve-lobed, the lobes 

 serrated, of a deep reddish-crimson colour, much brighter than 

 the variety atropurpureum. 1874. This presents a very striking 

 contrast to the last. 



A. p. septemlobum (seven-lobed).* fl. purplish, on numerous 

 flowered umbels. Spring. 1. varying much, from palmately five- 

 lobed, with toothed undivided lobes, to deeply seven to nine-lobed, 

 with more or less finely cut divisions. Japan, 1864. There are 

 numerous beautiful forms of this variety. 



There are many varieties of this much varying species, but 

 we have only mentioned those best known ; many are only 

 known by their native names, and there is some doubt as 

 to their distinctive characteristics. They are all extremely hand- 

 some. 



A. pennsylvanlcum (Pennsylvanian).* Jl. in long drooping, 

 simple racemes. May. I. cordate, three-lobed, acuminated, 

 finely and acutely serrated. A. 20ft. Trunk elegantly striped

 A. pictum (painted).* fl. corymbose, stalked. I. five to seven- 

 looed ; lobes triangular or oblong, entire, acuminated. A. 15ft. to 

 20ft. Temperate Asia, 1840. A. p. connivem (converging), A. p. 

 marnwratum (spotted), A. p. rubrum (red), and A. p. variegatum 

 (variegated), are varieties differing principally hi the colouring of 

 the leaves. All are very desirable. 



A. platanoldes (plane-like).* The Norway Maple. /. on nearly 

 erect stalked corymbs. May, June. I. cordate, smooth, flve- 

 lobed; lobes acuminated, with a few coarse acute teeth. A. 

 50ft. Europe, 1683. A very ornamental hardy tree, growing 

 with great rapidity when young. It prefers a deep, well-drained 

 soil. 



variegated).* I. variegated with 

 retain the variegation, requires 



to be propagated by budding or grafting. The same remarks are 

 equally applicable to the other varieties. 



A. p. lacinlatum (cut-leaved).* I. deeply and variously cut, green 

 and yellow. 



A. p. Schwedlerl (Schwedler's).* I. very large, deep bronzy-red. 

 A vigorous grower, and most effective. 



A. p. variegatum (variegated).* I. variegated with white. 

 There are several other varieties, but of less importance than 

 the foregoing. 



A. Pseudo-platanus (Mock-plane tree).* Sycamore, fl. on 

 rather compound pendulous racemes. May. I. cordate, with 

 five acuminated unequally-toothed lobes. A. 30ft. to 60ft. 

 Europe. There are few deciduous trees so well adapted for 

 standing singly in rough exposed situations. A deep, soft, dry 

 soil is most suitable for it, but it will grow in soils of very 

 opposite qualities. 



A. P.albo varlegata (white- variegated).* A very beautiful form, 

 in spring especially. I. white and green. 



A. P. flavo varlegata (yellow-variegated). I. variegated with 

 yellow. 



A. P. longlfolla (long-leaved).* I. more deeply cut, and the 

 petioles much longer than in the species. 



A. P. pnrpnrenm (purple).* I. purple underneath. The tree, 

 when slightly ruffled by the wind, alternately appearing clothed 

 in purple and pale green. Numerous other vaneties of more or 

 less excellence are grown. 



A. rubrum (red).* Scarlet Maple. /. scarlet, handsome, conglome- 

 rate, corymbose. I. cordate at the base, deeply and unequally 

 toothed, palmately flve-lobed, with acute recesses. Branches and 

 fruit also scarlet. A. 20ft. Canada, 1656. A variety with leaves 

 splashed with yellow is rare. An excellent species, thriving 

 well in damp, swampy situations, and is commonly increased by 

 layers. 



A. rufinerve (red-nerved).* "The leaves vary both in size and 

 outline, from 2in. to 4in. each way; three to flve-lobed, with 

 irregularly toothed margins, glabrous above, but with reddish 

 hairs along the nerves beneath. The young branches are con- 

 spicuous on account of the bluish-grey glaucescence with which 

 they are covered." 



A. r. albo llmbatum (white-margined)* differs only from the 

 species in having a very distinct white margin not always 



A. saccharlnum (Sugar Maple).* fl. yellow, on drooping corymbs, 

 on short peduncles ; pedicels pilose. April. I. cordate, smooth, 

 palmately flve-lobed ; lobes accuminated, sinuately toothed. 

 A. 40ft. N. America, 1735. 



A. s. nigrum (blackish).* fl. on sessile corymbs, nodding. April,
