Origin of the flora of the Malay Peninsula
Blumea. Supplement , Volume 1 - Issue 1 p. 183- 192
In my work on the Malay Peninsula, I included such plants as were known from the districts of North Kedah, Perlis and Setul. Botanically however, the Malayan flora ceases at a line running from a little north of Kedah peak Lat. 6.5, to Kota Bahru in North Kelantan Lat. 6.10. It is in fact approximately the termination of the Granitic Mountains as shown in SCRIVENOR’S Map of the Geology of Malaya. North of this line there is a remarkable sudden change in the flora (with also a change of climate and soil) from the Malayan to Indo-Chinese. More than 60 genera of typical Malay plants entirely disappear, and many more are represented by a single species which has crossed the line, and disappears in Tenasserim. Among these plants are the Durioneae, Lowiaceae, Schismatoglottis, Homalomena, Cyrtandra, Neuwiedia, Plocoglottis, Leptaspis and most of Palms. A few plants from southern Siam and Cambodia have invaded the north of the Peninsula chiefly on the East side where the soil is most suitable. It is quite clear that the Peninsula was separated from the Tenasserim—Siam region through the Isthmus of Kra at no very distant period of time and was thus an island. The whole of the Peninsula (Malaya) contains about 52.000 square miles, and is about 485 miles long and 200 miles wide in its widest part. It consists of a mass of mountains usually rising to 5.000 feet alt., with two, Gunong Tahan and Gunong Kerbau 7.000 feet alt., and is fringed on the west coast by lowlands with mangrove bordering the sea, and on the East coast with sandy plains. Except on the latter the whole country is covered by dense forest, the tallest trees being 180 feet tall so that on looking over it from an elevated point, nothing can be seen but the tops of the trees.
