414 MR. HENRY RIDLEY ON ORCHIDEH AND 
bifidum. Anthera brevis, in dorso carinata, apice truncata; 
rostellum longiusculum. 
Hab. Malacca: Mt. Ophir, alt. 3,000 feet ! 
Kedah: Kedah Peak, 3,000 feet ! 
This is a very slender small-flowered species, growing among 
moss in streams on these two mountains, and apparently rarely 
flowering, as I only met with a couple of plants in flower in 
each locality. It is allied to H. lacertifera, Benth., and H. tenta- 
culata, Reichb. f.; but the flowers are very much smaller, the 
bracts narrower, and the short spur is distinctly bilobed at the 
apex.

Hab. Lankawi Islands, Curtis, &c. 
It is remarkable that the only other locality known for this 
species is the Tembilan Islands, near Borneo.

Hab. Johore: Gunong Panti, a single plant in dense 
jungle ! 
Malacca: Mt. Ophir, abundant !Remban Hills ! 
Penang: Government Hill, abundant ! 
Kedah: Kedah Peak ! 
This well known species is often most abundant, sometimes 
covering rocks in masses, as on Penang Hill. On Mt. Ophir 
and Kedah Peak, though plentiful, it is more scattered, 
growing in moss by the stream in exposed places. Nearly all 
the named cultural varieties grow together. (@. superbiens, 
Reichb. f. in Bonplandia, iii. (1855) p. 227, Iam quite unable 
to distinguish specifically ; it seems to be merely a fine form, 
and said to have been obtained on Mt. Ophir ; it is commonly 
called “ Bunga Kusut” (Shoe flower) by the Malacca natives. 
I have found a few plants of a Cypripedium on the sea-shore, 
growing in sand beneath Pandani, in Johore, but the plant 
never flowered. It resembles a dwarf C. barbatum, but the 
leaves are much less distinctly marbled. It may prove a new 
species. 
Just outside the boundary, in Siam, grow C. insigne, var.
