396 ECONOMIC FORESTRY. 
Picea cephalonica and birch are characteristic of the mountains ; 
and willows, alders, and poplars, of the plains. 
2. The SourHeRN Steppes, TURKESTAN, and MonGo.ta, and 
3. 'THIBET,— are practically treeless. 
4. NortTHERN CHINA. 
The flora of the interior of China is but little known. Pinus 
koraiensis occurs in Corea, and P. Lungeana in Northern China, 
Larix Kempfert and Cupressus funebris are further representatives 
of the Gymnosperms. Oaks, among which are Quercus mongolica 
and Q. dentata, point to the connection of this flora with that of 
the Himalayas ; and other interesting trees, introduced into Eng- 
land about a century ago, are Magnolia Yulan (or M. conspicua, 
Salisb.), Kélreuteria paniculata, and Arlantus glandulosa. The 
“lily tree,” as the name Yu-lan signifies, reaches 40 or 50 feet 
in height, and is allied to other deciduous species in Japan and in 
the Himalayas. K6élreuteria paniculata, Laxm. (nat. order, Sapin- 
dace), grows only to 20 or 40 feet in height. Azlantus glandu- 
losa, Desf. (nat. order, Simarubee), reaching 50 or 60 feet, is known 
in German as “ Gotterbaum ;” in Italian, as “ Albero di paradiso.” 
It has been extensively planted near Odessa, and is commonly 
grown for ornament in England, and for shade in the eastern United 
States. It is the food of the Asiatic silkworm, Bombyx cynthia. 
The recent discovery of a tulip tree (Liriodendron; nat. order, 
Magnoliacee) in the interior, connects the flora of North China 
with the tertiary fossil floras of Europe, as well as with the existing 
flora of America.
