" M. Maratray, itispector o*" forests in tlit- department of Mount Jura, 

 sent, in 1H()7, to the Administration of Forests in Paris, a specimen of 

 this wood, wliich justified all that had i)ccn said of the fineness and homo- 

 geneousness of its grain. He also sent seeds, part of which came up the 

 first year, and the remainder tiie year following. The plants have n)ade 

 tolerable progress ; but it remains to be known, whether, in fertile soil, the 

 tree will preserve the valuable quality of its wood." {Trailer ^c.,\. p. 31.) 

 The plants have been distributed among the diHerent government gardens 

 of France; and particularly those of Versailles, under the direction of 

 M. Bosc. At Bollwyller, there are plants of this species which, it is said, 

 can be furnished of considerable size ; and they are designated in the Cata- 

 logue, " zl^cer opulifolium, non A. O'palus;" price 1 franc 50 cents. 

 There was a tree in the garden of the London Horticultural Society, in 

 1835, which differed somewhat from A. O'palus, and seemed to us inter- 

 mediate between that species and A. barbatum, or, as it was then marked, 

 in 1835, A. trilobatum ; but, whether it was the A. opulifolium of Villars 

 and Baudrillart, we are unable to say. 



t 13. A. ciRCiNA^TUM Purs/i. The round-leaved Maple. 



Identification. Pursh Fl. Amer. Sept., 1. p 2(i7. ; Doc. Prod.. 1. p. 595. ; Don's Mill, 1. p. 651. 

 Engraving. Hook. Amer., t. 39. ; and our fig. 112., anAfig. 127. in p. 454. 



Spec. Char., Sfc. Leaves orbicular, rather cordate at the base, 7-lobed, 

 smooth on both surfaces ; lobes acutely toothed ; nerves and veins hairy at 

 their origins. (Don's Alii/., i. p. 651.) A tree from 20 ft. to 40 ft. high. 

 Branchesslender, pendulous, and crooked; often 

 taking root, in the manner of those of many 

 species of 7mcus. Bark smooth, green when 

 young, white when fully grown. Leaf the 

 length of the finger, u[)on rather a short foot- 

 stalk, niembranaccous, heart-shaped, w ith 7 — 9- 

 lobes, and 7 — 9-nerves, smooth above, except 

 hairs in the axils of the nerves ; downy be- 

 neath, and in the axils of the nerves woolly : 

 lobes ovate, acute, and acutely serrated ; the 

 sinuses acute ; the nerves radiate from the tip 

 of the petiole, and one extends to the tip of 

 each lobe. Flowers (proiluced in April and 

 May) of a middling size, in nodding corymbs, 

 that are on long peduncles. {Hook. Fl. Bor. 

 A))/n:) This is a very marked and beautiful species ; distinguishable, at 

 sight, by the regular form of its leaves, and pale reddish green colour. 

 Geography. On the great rapids of Columbia River. (Lewis, in Pursh's 

 Fl. Am. Sept.) Common along the north-west coast of North America, be- 

 tween lat. 43° and 49 . (Douglas ; D. Scouler.) A. circinatum, like A. ma- 

 crophyllum, is exclusively confined to the woody mountainous country that 

 skirts the shores ; and there, among the |)ine forests, it forms almost impene- 

 trable thickets. (Douglas, in Hook. Fl. Bor. Amer., vol. i. p. 1 12.) 



Properties and Uses. The wood is fine, white, and close-grained, very 

 tough, and susceptible of a good polish. From the slender branches the 

 native tribes make the hoops of their scoop-nets, which they employ for 

 taking the salmon at the rapids, and in the contracted parts of the river. 



statistics. There is a plant of this species, in the London Horticultural Society's (iardcn, about 2fl. 

 high ; and one at Messrs. I/oddigcs's .-ibout the same height. In Kerkshire, at High Clerc, there Is a 

 tree which has blossomed and ripened seeds.
