AN. EXPEDITION TO MOUNT BATU LAWI. 63 
APPENDIX II. 
Orchids collected on Mr. Moulton’s expedition to Mt. 
Batu Lawi. 
Bye Re did) SO MECEe mn UlENZORG: 
Since Ridley published his enumeration of the Orchideae from 
Borneo, many new species have been described and several others 
only known from other parts of the Malayan region, have been added 
to its flora, but a somewhat satisfactory survey of the Orehid flora 
of the large island is still lacking. Every addition is to be re- 
garded as a step forward. 
The small but interesting collection made by Mr. J. C. Moulton 
on Mt. Batu Lawi consists of 18 numbers representing 17 species. 
It is to be regretted, that in no less than 7 species the flowers are 
in no state good enough to be described. Among the remainder, 
7 well marked new species were found. 
The genus Hria represents the bulk of the collection, containing 
7 species of which 3 belong to the small section Aeridostachya. 
The plant I take to be Hria cymbidufolia, Rid)., has elongate, 
15-20 em. long, 3-4 leaved stems. The leaves are obliquely sub- 
acute or subobtuse, where as Ridley describes them as bilobed. In 
the flowers too the description does not entirely suit Mr. Moulton’s 
plant. It is nearly related to #. cymbiformis, J. J.S., from Su- 
matra, which has, as a plant cultivated in the Buitenzore Botanical 
gardens shows, very short 8-10 leaved stems and pubescent inflores- 
cences and flowers. It belongs to the section Cymboglossum, as 
I think does F. longifolia, Hook. f., H. lawiensis, J. J. 8., is a very 
inconspicuous plant of the Trichotosia section. 
Coelogyne is represented by 3 species, of which one without 
flowers. C. Moulton, J. J. 8., with very large bracts seems to he 
the most showy plant of the collection and is allied to C. Dayana, 
Rchb. f., O. gibbifera, J. J. 8., is a member of the Lonaifoliae sec- 
tion. 
The two Dendrobes are both allied to D. crumenatum, Swartz, 
with very fugaceous flowers. D. lawiense, J. J. S., is well marked 
by the elongate lip. 
It is rather remarkable, that the two species of Dendrochilum 
belong to the very few representatives of the section Platyclinis 
with an elongate rhizome. 
The Phajus is very similar to Ph. callosus, Lmdl.. hitherto not 
vet recorded from Borneo. he lip is however more cuneate as in 
the Javanese specimens and the midlobe smaller. Perhaps it is 
another species.
