barbhtum, of which a leaf is figured in the Penny Cyclopaedia, and several in 

 our fg. 125. p. 452., may possibly be only a variety of A. Pseudo-Platanus, 

 diminished in all its parts. A. coriaceum, which we consider as a synonyme 

 of A. O'palus, and which, in the Penny Ci/cl., is considered a synonyme of A. 

 creticum, may be a more distinct sort than we think it is, from having seen 

 only small plants of it. These small plants have leaves as nearly as possible 

 of the same form as those of^. tXpalus, exhibited in Jig. 126. p. 4-53.; and, 

 therefore, the A. coriaceum mentioned in the Penny Cycl. as a synonyme of 

 A. creticum, must refer to a different plant from the specimen of A. coriaceum in 

 Loddiges's arboretum. A. LobehzTenore, of which there is a tree, 20 ft. high, 

 at Croome, in Worcestershire, certainly appears very distinct from A. />lata- 

 noides (of which we have set it down as a variety) in the foliage of the plants 

 about 2 ft high in the London nurseries ; but not so in the specimens which 

 we have received from Croome. A. nigrum, which we consider as a variety 

 of A. saccharinum, oug^ht to be proved by raising plants from seeds, which can 

 be procured from America at the same price as those of A. saccharinum. 

 It would not surprise us if A/flatanoides and A. saccharinum were ultimately 

 to turn out to be races of one and the same species. Under the name of A. 

 hybridum, it is probable that there is more than one variety or species in cul- 

 tivation. The A. hybridum of Bosc, with coriaceous leaves, profoundly trifid, 

 seems to be different from the A. hybridum of Baudrillart, which he describes 

 as intermediate between A. monspessulanum and A. tataricum. In Don's 

 Miller, there is A. obtusifolium Flor. Grcec., t. 361., a native of Crete; and 

 there is also A. obtusatum Kit., a native of Hungary : these may possibly be 

 names applicable to one and the same species. A. lobatum Don s Miller, i. 

 p. 651., a native of Siberia, and said to have been introduced in 1820, is there 

 designated an " extremely doubtful " species. 



A pp. ii. Anticipated Species of A^cer. 



All the species of this family are so interesting and ornamental, that it is 

 desirable to procure additions to those already introduced into Britain, from 

 every quarter of the globe, and by every resource which art supplies. It 

 appears, from Don's Miller and Royle's Illustrations, that there are one or 

 two European species, one from N. America, several from the Himalayas, and 

 some from Japan, all likely to prove hardy, which are at present wanting in 

 British collections. We shall give the names of these, in the hope of direct- 

 ing to them the attention of travellers, collectors, and patriotic amateurs. 



y- A. ibdricum Bieb., a tree 20 ft. high, native of Iberia, with greenish yellow flowers, and 

 shining 3-lobed leaves, is described in Bieberstein's Flora Taurico-Caucasica, vol. ii. p. 447.; in Dec. 

 Prod., i. p. 594. ; and in Don's Mill., 1. p. 649. 



3f A. obtusif<>lium Sibth. and Smith, a native of Crete, a tree 15 ft high, with 3-lobed crenated 

 leaves, is described in the Flora Grteca, and in Don's Mill. ; in the latter work it is mentioned as 

 being of doubtful introduction. 



J A. parvifhlium Tausch is described as having 5-lobed leaves, and nodding corymbs of flowers. 

 It is a native of the south of Europe, growing to the height of 20 ft., by some confounded with A. cre- 

 ticum, and by others with A. monspessulanum. 



$ A. glabrum Torrey has smooth roundish 5-lobed leaves, and is found in North America, on the 

 Rocky Mountains. Very little appears to be known of this species. 



3f A. leevigutum WalL has oblong, acuminated, smooth, shining, leaves, and white flowers. It is a 

 native of Nepal, on high mountains, where it forms a tree 40 ft. high. It is described and figured 

 by Dr. Wallich in his Plant. Asiat. rar., 2. p. 3. t. 104. 



A. acuminatum Wall., a tree of Nepal, with leaves varying from 3-lobed to 5-lobed, is described 

 in Don's Prod. Fl. AYp., p. 249. 



$ A. cultratnm Wall., a tree of Himalaya, with cordate, 7-lobed, acuminated leaves, is described 

 by "Wallich in his Planta. Asiatics rariores, vol. ii. p. 4. 



*t A. caudatum Wall., a tree from the highest regions of Nepal, with long pointed leaves, is de- 

 scribed in the work last quoted, voL ii. p. 4., and in Don's Mill., i. p. 648. 



5^ A. viilbsum W r all., a tree 50 ft high, native of the high alps of the Himalaya, near to perpetual 

 snow, has cordate 5-lobed leaves, and fragant flowers. It is described in Dr. Wallich s work, and in 

 Don's Mill., as before quoted. 



3f A. sterculiaceum Wall., is a tree .00 ft. high, with a trunk 3 ft. in diameter. The leaves are very 

 lare, with long petioles, and the flowers are white. It is found in Noj>al, on Mount Shiojmre. 



Y A. dinxt'cluin Thun. is a tree of Japan, with leaves 9 10-partcd, and oblong acuminated lobes, 

 with a ml corolla. It is described by Thuiibcrg in hi Flora Janonica, p. HiO. ; in Dec. Prod., i. 

 p. 955. ; and Don's Mill., i. p. 650.
