SiLVicuLTURAL CHARACTERS. The tree is a moderate light-demander, and 

 is often found as an undergrowth species in open deciduous forest. In the 

 abnormal drought of 1907 and 1908 in the forests of Oudh it proved to be 

 fairly hardy, though not so hardy as Holarrhena. It coppices well, and has 

 good power of recovery from injury. It is somewhat frost-tender. 



Natural reproduction. Under natural conditions germination takes 

 place at different times during the rainy season. Some mortality occurs 

 among seedlings owing to drought during breaks in the rains. Reproduction 

 is most plentiful on clear loose ground free from weed-growth. 



Artificial reproduction. Weeded line sowings carried out as in the 

 case of Holarrhena give good results. For transplanting purposes seed should 

 be sown in the nursery about March or April : the seedlings ordinarily appear 

 above ground in three to four weeks, and may be transplanted during the first 

 rainy season, but care is necessary during transplanting, otherwise they are 

 liable to die back or to be killed outright. 



Rate of growth. A cross-section in the silvicultural museum at Dehra 

 Dun had 31 rings for a girth of 2 ft. 5 in., giving a mean annual girth increment 

 of 0-94 in. Gamble's specimens gave an average of 8 rings per inch of radius, 

 or a mean annual girth increment of 0-78 in. Measurements of one tree 

 extending over a period of nine years in the Kishanpur working circle. South 

 Kheri, United Provinces, gave a mean annual girth increment of 0-4 in. for 

 the period.

A small deciduous tree of the Indian Peninsula, extending northward to 

 Rajputana and Banda. This is a common tree in the Deccan in open deciduous 

 forests, often on trap ; it extends southward in considerable abundance to 

 Travancore, and is found most commonly on dry sandy soil and on hilly 

 ground. It is also found in Burma. The new leaves and white flowers appear 

 from March to June and the fruit ripens in January-February. The fruit 

 consists of a pair of slender follicles cohering at the tips only. The tree stands 

 moderate shade, and is often found as an undergrowth species in deciduous 

 forests. It produces root-suckers. The growth is slow to moderate. A cross- 

 section in the silvicultural museum at Dehra Dun had 24 rings for a girth 

 of 11 in., giving a mean annual girth increment of 0-46 in. Gamble's specimens 

 gave 7 rings per inch of radius, or a mean annual girth increment of 0-9 in.
