Dear Henderson 
I am today despatching 80 duplicates 
and 38 mounted sheets. Please return the latter at your 
convenience. These are all my collections from Gunong Stong 
a few being from the base and lower slopes but the majority 
from near the summit. I am sending these that you may judge 
for yourself concerning the incidence of a limestone flora 
from the evidence these collections provide. The following 
numbers collected on or beside limestone rocks will interest 
you particularly - 37674, 37713 - 37716, 37721 - 37724, and 
37726 - 37728. I shall be much interested to know if any 
of these plants are typically found in limestone habitats. 
2 . I have some additional collections 
from the neighbouring hills of Bukit Ayam and Gunong Sagi 
which I shall send if you would like to see them and compare 
them with Stong. 
3 . I shall be grateful for your 
identifications of the Stong collections most of which 
I have not had time to tackle yet.
