Acacia pennata. 

 Acacia caesia. 

 Cryptolepis Buchanani. 

 Vitis sp. 



Parasitic Loranthaceae are also very common in these 

 forests. The limits of the distribution of some of the most im- 

 portant species of these forests, i.e. of Sal, Teak, Sandal and 

 Red Sanders, are shown in Plate XXIII. 



The Sal is strongly gregarious, and is by far the most 

 numerous tree in the forests in which it occurs. In the Sub- 

 Himalayan tract the Sal forests usually occupy the higher 

 tracts of old alluvium lying between the rivers, while the more 

 recent alluvium, consisting of beds of shingle and sand, in and 

 near the river beds, is often covered with gregarious forests of 

 Sissoo and Khair. 



In damp places in the Sal forests, the Indian Red Cedar 

 (Cedrela Toona), Trewia nudiflora, and Pterospermum aceri- 

 folium are common. 



The Teak, unlike the Sal, usually occurs in mixed forests,) 

 where it frequently forms only a small proportion of the stock. 

 Although the Sal and Teak areas meet in Central India and to a 

 certain extent overlap, these trees are not found together. An 

 isolated patch of Sal for instance occurs inside the Teak area, at 

 Pachmarhi, in the Central Provinces. Teak is occasionally 

 found practically pure on alluvial ground, but its best growth 

 is obtained on well drained slopes. A large number of species 

 found in the Indian Teak area are also found in the Teak forests 

 of Burma and, besides those already mentioned, the Ironwood 

 of Pegu and Arracan (Xylia dolabriformis) should be noted. On 

 the other hand several species found in the Indian area do not 

 extend to Burma and vice versa. In the Indian area the follow- 

 ing are important trees : 



Pterocarpus Marsupium (Bijasal). 

 Pterocarpus santalinus (Red Sanders). 

 Hardwickia binata (Anjan). 



Dalbergia latifolia (Shisham, or Bombay Black Wood). 

 Chloroxylon Swietenia (Satin Wood). 

 Ougeinia dalbergioides (Sandan, or Tinas). 

 Santalum album (Sandal). 



The Burman Teak forests on the other hand contain such 

 species as 



Dillenia parviflora. 

 Homaiium tomentosum.
