up to 19,000 ft. north of the main range. In the foot-hill zone there is a 

 sub-tropical element with some plants which range as far as the Philippines. 

 In the Indus Valley there are desert plants ranging to the Mediterranean. 

 There are temperate and alpine plants which are found in various places as 

 far away as the Alps and others which apparently have come in from China. 

 Behind the Great Range the flora becomes like that of Tibet and Central 

 Asia. 



Although the flora is most varied, the total number of species is probably 

 not more than 2,500 and in addition there are about one hundred ferns. 



Main Zones 



I Sub-montane, largely varied types of thorny scrub. 



II Pinus longifolia zone, 3-6,000 ft. 



III Pinus cxcelsa and temperate hardwood zone, 6-8,000 ft. 



IV Abies IVebbiaua zone, 8-11,000 ft. 



V Betiila BJiojpattra zone, 11-12,000 ft. 



VI Zone of shrubs, rhododendrons, willows, junipers, 12-13,000 ft. 



VII Alpine meadows of herbs and grasses and sedges, 13-14,000 ft. 



VIII High alpine zone of moraine and rock plants, 14-19,000 ft. 



These zones apply to the Indian side of the main range of the Himalayas 

 and the altitudes vary a good deal according to exposure, rainfall, etc. 



Behind the crest of the main range the forests disappear and closed forma- 

 tions are not common. Trees and crops have to be irrigated. 



The meeting was adjourned at 9.35 p.m.
