262 ME. H. N. RIDLEY—AN ENUMERATION OF 
of Kra to Java inclusive, is, as regards Orchids, at least tolerably 
homogeneous. The Dendrobia, among others, mark off the 
Malayan regions very distinctly. In India and Siam occur the 
sections Stachyobium and Eudendrobium, with the great section of 
Speciose (e. g. D. nobile, Lindl., D. aggregatum, Roxb.). These 
are nearly absent from the Malayan region, of which the most 
characteristic sections are Aporum, Strongyle, Cadetia, Pedilonum, 
and Distichophylle. In the Papuan region occurs the Tuurinum 
section with twisted petals, quite absent from the Malayan region. 
The most characteristic genera of the Malay region are Platy- 
clinis, Dendrochilum, Nephilaphyllum, Thelasis, Microsaccus, 
Adenoncos (Sarcochilus), Appendicula, Podochilus, and Ploco- 
glottis. 
The Orchids of the highest ranges of Mt. Kinabalu are typi- 
cally Malayan. There is nothing to show any connexion with 
the Himalayan flora; though from the other plants collected by 
Dr. Haviland and the fauna obtained there, it appears that there 
is a decided trace of a Himalayan element. I have added some 
notes on the Apostasiacee, not because I consider them to bear 
close relationship to the Orchids, but rather for convenience, 
since it is usual for botanists to look for accounts of these plants 
under Orchidee.

This is chiefly remarkable for the minuteness of its flowers, 
which are much smaller than those of most Oberonias. It 
really belongs to the Caulescentes, though the stem is very 
short.
