India Rubber and Gutta Percha. 51 
The original Hevea guyanensis of Aublet was based 
upon specimens in fruit, of which flowers were unknown. 
The Hevea identified by Largot, and in conjunction with 
Aublet's plant is quite distinct from Mr. Jenman's. The 
name to adopt here is Hevea spruceana, Mull. Org. 
This satisfactorily settles the identity of the plant." 
The Indians, having once seen the tree, appeared quite 
familiar with it, and promised to take me next day to a 
locality where I should find many, and larger specimens. 
Early in the morning we started to see these trees. The 
place was not far distant from where we discovered 
those on our return journey the previous evening. They 
were very plentiful. The situation is a tract of low 
alluvial land along the bank of the river, which in the 
rainy season is quite submerged, often apparently deeply. 
At the time of my visit the water had just shrunk away 
in the general fall of the river, consequent on the cessa- 
tion of the heavy rains in the interior a month or six 
weeks before. Residents on the rivers say they never 
remember the water to have been so high as it was 
during the past season ; but though there had been little 
diminution of rain in the lower parts, the rivers had sub- 
sided rapidly, showing that on the great water-sheds of 
the interior the rain had in great measure ceased. 
The exceptionally heavy rains experienced on the 
coast lands were evidently general throughout the colony. 
On landing, the ground was found to be still quite 
soft, and it was hardly possible to walk without sinking 
to the ankles or deeper in the surface deposit of mud. 
The forest was high and dense, producing a deep gloomy 
shade within, and there was little under-growth. The
