from the west and has as its main tributary the Menam Chi, which 

 supplies a large part of the plateau. The discharge from two shallow 

 but extensive lakes in the north is effected by tlie Menam Pau, a trib- 

 utary of the Menam Chi. In the eastern part of the plateau is Lake 

 Lahan, having an area of about 170 square kilometers, the largest 

 fresh-water lake in the country, which is both flooded and drained by 

 the Nam Kam. The only other noteworthy stream is the Menam 

 Songkram, which enters the Mekong from the northeast section of the 

 division. WHien the Mekong is in flood there is a strong reverse 

 current in all the tributary streams. 



Southeastern Thailand is a small division lying south of the Bangpa- 

 kong and bounded on the east by the Bantad Range forming a part of 

 the Cambodian border and on the west by the Gulf of Siam. It has a 

 A'aried topography, with a detached mountain range (Chantabun 

 Mountains), forested plain, extensive tidal areas covered with marsh 

 grass and mangrove swamps, short rivers of which the principal are 

 the Chantabun, the Wain, and the Trad or Krat, and numerous rocky 

 jungle-clad fringing islands. The largest island, Koh Chang, is 30 

 kilometers long with an area of 180 kilometers. It is forest-clad and 

 very rugged, with the highest of the peaks 644 meters, and in clear, cool 

 rockv streams below picturesque waterfalls there is an interesting fish 

 life'." 



GAZETTEER OF COLLECTING LOCALITIES IN THAILAND 



In the Thai language generic prefixes are commonly applied to 

 geographical names (i. e., «<?, gulf, bay, bight; han^ village). In this 

 gazetteer the generic prefixes are given in parentheses following the 

 name [cf. Kong (Mae Nam) for Mae (Nam) Kliong; in the text of the 

 catalog the name used would be Mekong] . This has been done for the 

 sake of consistency even where foreign usage treats the prefix as an in- 

 herent part of the name. Such names as Ban Mae Sot ("Village of the 

 River Sot") and Doi Mae Kong Ka ("mountain of the River Kong Ka") 

 are listed as Mse Sot (Ban) and Mse Kong Ka (Doi). 



In every case the spelling of the name proper used in the text has 

 been placed first [i. e., Mekong (Kong being considered the name 

 proper) would be listed as Kong (Me or Mse, "river," generic prefix, 

 understood)], instead of Kliong. Whenever such transliteration dis- 

 agrees with that used (since 1940) by the Royal Survey Department at 

 Bangkok, the name is given also, as a subsidiary to the spelling used in 

 the text, according to the more recent system. In certain instances a 

 frequently employed (and sometimes mandatory) alternative name is 

 listed as well (i. e., the dialectic spelling Nang Ka for the mountain 

 correctly pronounced Langka and now officially named Pha Cho) .
