 carjmin. 



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

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

 A. tartaricum, 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. 



A. glabrum (smooth).* Jl. corymbose, on short two-leaved 

 Iiranchlets, greenish-yellow. June. I. rormdish-cordate, deeply 

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

 /. manydubfd, in early spring very light green, h. 20ft. Japan, 

 1863. The varieties nf this species, aUlioughnot well fixed in many 

 cases, rank aumngst the most handsome of the deciduous small 

 shrubs grown, liut often cliange in character as they attain any 

 considerable size. Plants from lift, to 3ft. high ai'e very useful in 

 cool conservatories, and in the highly kept giounds surrounding 

 the bouse.

 ntimerous beautiful forms of this variety. 



Tliere are many varieties of tliis much varying species, but 

 we have only mentmueil 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. pennsylvanicum (Pennsylvanian).* Jl. in long drooping. 

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

 finely aud acutely serrated, h. 20ft. Trunk elegantly striped 

 with white lines. North America, 1755. Sv.\. A. striatum. 



A. pictutn (painted).* Jl. corymbose, stalked. I. five to seven- 

 lobed ; lobes triangular or oblong, entire, acuminated, h. 15ft. to 

 20ft. Temperate Asia, 1840. A. p. eon«/rc/w (converging), A. p. 

 marmorat inn (spotted), A. p. ntbrum (red), ana A. p. vnrUfiatum 

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

 the leaves. All are very desirable. 



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

 erect stalked corymbs. ISIay, June. I. cordate, smooth, tive- 

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

 50ft. Europe, 1683. A very ornamental hardy tree, gi-owin^ 

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

 soil. 



A, p. aureo variegatum (gohlen-variegated).* I. variegated \vith 

 yellow. Europe, 1383. 'Ibis, to retain the variegation, requires 

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

 equally applicable to the otlier varieties. 



A. p. laciniatum (cut-leaved).* I. deeply aud variously cut, gi-een 

 and yellow. 



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



A vigorous grower, and most effective. 



A. p. variegatum (variegated).* I. variegated ■^vith white. 

 There are several other varieties, but of less importance than 

 the foregoing. 



A. Pseudo-platanus (Mock-idane tree).* Sycamore. Jl. on 

 rather com]>ouiid jn'odulnus racemes. May. I. cordate, with 

 five acuminated uneiiually-toothed lobes. h. 30ft. to 60ft. 

 Euro|)e. There are few deciduous trees so well adai>ted for 

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

 soil is most suitable for it, but it will gi'ow in soils of very 

 opposite qualities. 



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

 in spring especially. I. white and green. 



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

 yellow, 



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

 petioles much longer than in the species. 



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

 when sli^litly ruffled by the wind, alternately appearing clothed 

 in purple ami pale gieen. Numerous other varieties of more or 

 less excellence are grown. 



A. rubruin(red).* Scarlet Maple. H. scarlet, handsome, conglome- 

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

 toothed, palmately five-Iobed, witli acute recesses. Branches and 

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

 splashed with yellow is rare. An excellent species, thriving 

 well in damp, swampy situations, ami is coumionly increased by 

 layers. 



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

 outline, from 2^iu. to 4in. each way ; three to tive-lobed, with 

 irreiiularly toothed margins, glabrous above, but with reddisli 

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

 spicuous (ui account of the bluish-grey glaucescence with which 

 they are covered." 



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



species in having a very distinct white margin— not always 

 constant. Japan, 1869. 

 A.saccharinuin(Sngar Mai>le).* rf. yellow, on drooping corvnnbs, 

 on sliort pedinicles ; ]iedicels pilose. April. I. conlate, smooth, 

 palmatelv five-Iobed ; lobes accuminated, sinuately toothed 

 A. 40ft. N. America. 1755. 



A. s. nigrum (blackisli).* .//. on sessile corymbs, nodding. April, 

 Mav. l. cordate, with the recess closed; palmately tive-lobed. 

 h. 40ft. North America, 1812.
