ARE AE ae CuO. ah spr Ss, 
and ‘Amur, in the Chinefe dominions. The White Poplar, Populus alba; and the 
Afpen, Populus tremula, are extremely common, The Black Poplar, Populus 
nigra; the Common Sallow, Salix caprea; Sweet Willow, Salix pentandra; 
White Willow, Salix alba, are very frequent. The Hazel, Corylus Avellana, is 
circumftanced like the Oak. The Common Birch, Betula alba, is moft abundant ; 
and, as in all northern nations, of univerfal ufe. The Dwarf Birch, Betula 
nana, is confined to the neighborhood of lake Baikal. The Alder, Betula Alnus, 
is very frequent. The Pinafter, Pinus Pinea; the Pine with edible feeds, or Pinus 
Cembra; and Larch, Pinus Larix; all trees of the firft ufe, medicinal or cecono- 
mical, cover many parts of the country. The Norway Fir, Pinus Abies, and 
the Silver Fir, Pinus Picea, form, in moft parts of the country, great forefts : 
the firft grows in this country not farther north than lat. 60; the laft not higher 
than lat. 58; yet the former flourifhes in Europe, and compofes in Lapmars, far 
beyond the 4réic circle, woods of great extent: a proof of the fupcrior rigour of 
cold in the Afatic north. “Thefe form the fum of European trees growing in 
Sibiria. Ofother plants, commen to both continents, M. Gmelin gives the reader, 
in p. xciv. of his Preface, a flender lift of fuch which fell under his obferva- 
tion. 
The trees or fhrubs peculiar to Szbiria and Tartary, are the Acer Tartaricum, 
Sp. Pl. ii. 1495: the Ulmus pumila, 327: Prunus Sibirica, Amman. Ruth. 
272, tab. 29: Pyrus baccata, 274: Robinia Caragana, frutefcens, and pygmea, 
Sp. Pl. ii. 1044. I may alfo obferve, that the Taccamahacca, or Populus balfa- 
mifera, 1463, common alfo to North America, abounds about the upper part of 
the Lena, the Angara, and Fenefei, and between the Oxon and dga. An 
infufion of its buds is ufed by the natives as an excellent remedy for an infa- 
mous diforder, frequent in this great country. 
Europe is obliged to Sibiria for that excellent fpecies of Oat, the Jvena 
Sibirica, Fl. Sib. i. 113. tab. 22. Lin. Sp. Pl. i. 1173 and our gardens are in 
a moft peculiar manner enlivened with the gay and brilliant flowers introduced 
from that diftant and fevere climate. I fhall only fele&t a few out of the mul- 
titude *. Veronica Sibirica, Iris Sibirica, F\. Sib. i. 28. Eryngium planum, i. 185. 
Lilium bulbiferum, i. 41. L. pomponium, i. 42. L. Martagon, i. 44. Delphi- 
nium grandiflorum, Sp. Pl. i. 749.  LErythronium Dens canis, i. 39. tab. 7. 
Hemerocallis flava, i. 37. Saxifraga craffifolia, Sp. Pl. ie 573. Lychnis chalce- 
donica, Sp. Pl. i. 625. Pyrus baccata, Lythrum virgatum, Sp. Pl. 642. Amyg- 
* This lift was communicated to me by an able botanift; but I think fome of the plants are alfo 
found in Europe. :
