Mf. Lindhard gives llie following sketch of the counlry and the vegetation 

 in the Raheng District : 



« The Raheng District is situated at about 16° V« lal- N-, and the 

 river-valley with the town lies about 400 feet above the sea-level. It is 

 bounded on the western and southern side by mountains reaching a 

 height of about 5-8000 feet. The Ma-Ping River winds itself through the 

 middle of the district, from North to South and East. Wang Chow forest 

 with « the Wang Chow creek » lies on the south-western bank of the 

 river, 16 miles below Raheng. The collection has taken place alongside of 

 this, on the places mentioned beneath. 



« The district may, as regards climate, most appropriately be compared 

 to that op Lower Burma. The rainfall, however, is much smaller here in 

 Wang Chow forest, in as much as the boundary-mountains break the 

 free passage of the south-western Monsum, 



« The reasons are very marked, dry in thewinter-sixmonths,andwetin 

 summer. The rain commences in March or April; after a few so-called 

 Mango-showers some very intense thunder-showers occur, generally about 

 the close of April, and then the rain continues all through the summer 

 with shorter ar longer intervals (1-4 weeks). The downpour is in June 

 and especially in July often comparatively sparing, but is almost always 

 extremely plentiful in September and October. The rain closes about 

 November. 



« During the rainy period the atmosphere is moist and the sky often 

 cloudy. The temperature lies then normally between 80° and 90° F. 

 and there is but little difference between day and night. The temperature 

 rises, however, preceeding rain after a dry period of sliort duration, and 

 it falls distinctly after a considerable rainfall. 



« After the cessation of the rainy period, in November, the climate 

 presents great similarities to our Scandinavian September. The air is 

 high and clear, and the nights become cooler and cooler as the days go 

 by. Around New-year the temperature is down at about 50° F. Then 

 little by little the air becomes hazy and smoky, and the nights are 

 close. Gradually everything dries out, and the heat becomes more and 

 more unbearable. The temperature reaches in March and the beginning 

 of April up to more th;in 100° F. and not rarely does it reach 105°-107° F, 



« The vegetation is naturally extremely varyingaccordingto the different 

 seasons of the year and to the character of the soil ; especially it is decided 

 by the smaller or greater degree of moisture of the soil. In the higher 

 mountains may be found coniferous forests and meadows with stagnating
