7. Region of the Scitaminece (Indian^ or Roxburgh's Region). 

 Mean temperature, 66-83 Fahr. (19-29 C.). 



This corresponds nearly to Grisebach's Indian Monsoon region, and is 

 tropical in character, varying according to altitude and the direction of 

 winds, the degree of moisture, &c. The growing period for plants is in 

 the rainy season. It includes the Indo-Malayan region with the islands 

 of Java, Borneo, New Guinea, &c. 



Character. The tropical Orders make their appearance, or become more 

 abundant : Palmacese, Cycadaceae, Scitamineae, Aroidese, ArtocarpaceaB, 

 TJrticaceae, Euphorbiaceas, Lauracese, Convolvulaceee, Bignoniaceaa, Apo- 

 cynaceae, Rubiaceae, Leguminosa3, Terebinthacese, Meh'aceae, Guttiferee, 

 Sapindaceae, Byttneriaceee, Malvaceae. 



The extra-tropical vanish, or only present themselves sparingly : Cari-

 is greater than outside the tropics. Large and splendid flowers. Many 

 climbing, parasitical, and epiphytic plants.
