ARBOIIE'IUM AND FRUTICETU-M. 



PART III. 



Canada, of liigh mountains 

 in New York and I'cnn- 

 sylvania, where it does not 

 grow above 2 ft. or 3 ft. high, 

 and flowers in May and June. 

 The root is red, and is used 

 for inlaying. It was intro- 

 duced in \7C)2; and there 

 are plants at Messrs. Lod- 

 diges's. It appears but little 

 ditterent from the preceding 

 sort, and both are probably (j^) 

 only stunted varieties of B, 

 alba. ^,

Sjjec. Char., Sfc. Leaves orbicular, crenate, reticulated with veins beneath. 

 (Eng. Fl.y iv. p. lo4.) A bushy shrub, seldom exceeding 2 ft. or 3 ft. in 

 height ; v/ith numerous branches, slightly downy when young, and beset with 

 numerous, little, round, firm, smooth, siiarply crenated 

 leaves, beautifully reticulated with veins, especially 

 beneath ; and furnished with short footstalks, having 

 a pair of brown lanceolate stipules at their ba.se. Cat- 

 kins erect, stalked, cylindrical, obtuse ; the barren ones 

 lateral, and the fertile ones terminal. Scales of the 

 latter 3-lobed, 3-flowered, permanent. Stigmas red. 

 {Smithes Eng. FL, vol. iv. p. loj.) A native of Lap- 

 land, Sweden, Russia, and Scotland, in Europe ; and of 

 Hudson's Bay, and other parts of Canada, in America; 

 on mountains, but almost always in boggy places. Ac- 

 cording to Pallas, it is common in the whole of the 

 north of Russia and Siberia ; but not on the moun- 

 tains of Altai or Caucasus. In wet situations, he says, 

 the shoots grow to the length of G ft. ; and, in a state of 

 cultivation, they grow as high as 9 ft., and assume an erect form. This shrub 

 is of singular use in the domestic economy of the inhabitants of Lapland. 

 Its branches furnish them w ith their beds, and their chief fuel ; its leaves, 

 with a better yellow dye than that obtained from the common birch; its 

 seeds afford nourishment to the ptarmigan, or white partridge (7'etrao 

 Lagopus Z/.), w hich supplies a considerable portion of their food, and also 

 forms an important article of commerce ; antl, for their medicine, it produces 

 the fungus Poly[)orus fomentarius JMich., respecting which some details will 

 be found under the head of Quercus, sect, libhur, from which themoxa, or 

 amadou, is prepared, and which the Laplanders consider an efficacious 

 remedy in all painful diseases. Such is the wonderful power of adaptation 

 of man, in a country possessing few natural resources. B. nana lias been 

 in cultivation in Britain since tlw; days of Miller, and is by no means un- 

 frequent in collections. Price of plants, in the London nurseries, is 2.V. 

 each ; and of seeds, Gd. per packet. At New York, plants are 25 cents each.
