Vaccinium longibracteatum , /.bancanum , 
Plea, Carallia, Ficus, Oreorhamnus, Baeckia 
and Leucopogon # Dacrydium was common but 
Lepto^spermum"was the dominant tree species 
as on Tapi's. In the undergrowth were 
Dipteris, Oleandra, Matonia and G-leichenia, 
tfambusaelegansV (Jahnia tristis, Xyris gran - 
dis, Gaertnera," Rh'ododendron malayanum, and 
other typical plants of this formation. 
An unusual and interesting find was 
Orchadocarpus on the damp overhanging 
surfaces of rocks near the summit. The 
Xyris is also of particular interest being 
mown only from Tahan and Stong. We were 
disappointed, believing the summit to be 
limestone, to find no calcicoles appearing 
among the flora. We examined the rocks with 
some care as we ascended and found that 
these were entirely of what we take to be 
granite with the exception of a few small 
inclusions of chrystaline limestone at about 
200* from the summit. These inclusions 
were surrounded by granite rocks and the 
summit itself is of granite. Whether the 
limestone exposure is too small to support 
a calcicolose flora or whether it is too 
recent and isolated to have been colonized 
by calcicolous species, it is difficult 
to say but it is clear that no such flora 
has developed. The only plant collected in 
the vicinity of the limestone and not found 
elsewhere was the Orchadocarpus but this plant 
is to be found on acid rocksin other 
localities.
