They also approximate to the botanical Sub-areas of British India drawn up by Mr.C. B. Clarke in his instructive Essay in the Journal of the Linncan Society (vol. xxxiv (1898), p. 142),with an excellent map. The principal differences between his Sub-areas and my Regions lie in his inclusion of Central Nepal of the Afghan E. the Eastern Himalayan Region, and in boundary mountains, all Baluchistan, SE. Rajputana, and Central India in the Indus Plain Region in his treatment of N. and NE. Burma with the Assam Valley as a separate Subarea (Assam), and of Eastern and Southern Burma as another (Pegu) ; and in his inclusion of all Ceylon in the Deccan; Region.
The Flora of British India has been described at greater length than in this Sketch in the much Introductory Essay to Thomson's and my Flora Indica (see footnote, p. 157). In that work three primary divisions are recognized namely, I. Peninsula from the base of the Hindustan, including the Western Himalaya to Cape Comorin II. The Himalayas; III. India beyond the Ganges. These primary divisions are subdivided into sixty-four Provinces, the botanical characters of which, as they were then known, were delimited in relation to their climate, geographical position, elevation above the sea, and far as other physical conditions; to which are added references to many of the botanists who had explored them, their collections and their works. These sixty-four Provinces will, I believe, all prove to be deserving of detailed botanical treatment when materials shall have been obtained to effect this. The following is the list of them, arranged arranged under the Regions adopted in this Sketch:....
1. Eastern Himalayas:Mishmi, Abor,Bhutan,Sikkim,Central Nepal.
2.Western Himalayas, under three groups: 1.Kumaun,Ghrhwal, Simla, Kulo, Chamba, jammu, Rajaor8i, II. kanawar, Lalul, Kishtwar, kashmir, murrece, III gugi, PiTi and Parang, Zskar, Dras, Nari, Ladakh, Balti, Nubra
3. Indus Plain, which includes the Punjab, Sind, Cutch, Northern Gujarat, and Rajputana west of the Aravalli Hills.
4. gangetic Plain, under two groups; I. Upper, including Rajaputana east of the Aravalli hills, Bundelkhnd, and Malwa. .
A fourth is devoted to Afghanistan and Baluchistan, which countries not being in British India are not included in this Sketch, except a small area in Baluchistan since acquired. See Appendix B, p. 209.
