316 MR, H. N. RIDLEY ON A COLLECTION OF 
DISCHIDIA ALBIDA, Griff. Notule, iv. 46, 
Gunong Tahan. On trees ; flowers pale yellow. (5899.) 
Distrib. Malay Peninsula. 
GENTIANACE. 
GENTIANA MALAYANA, n. sp. 
Herba pusilla 1-3 poll. alt. Folia carnosa congesta aeuta lanceolata 
sessilia integra glabra, 1-3 poll. longa. Flos terminalis 1 poll. longus. 
Calyx tubulosus, lobis acuminatis tubum corolla superantibus. Corolla 
azurea tubulosa, lobis brevibus subspathulatis apicibus rotundatis, plicis 
integris. Stamina antheris longius hastatis predita. Ovarium stipi- 
tatum ; stylo brevi, stigmatibus brevibus. 
Gunong Tahan, 5000-6000 ft. Flowers deep sky-blue. Growing among 
moss in damp places (5473) ; on wet rocks (5479). 
The addition of the genus Gentiana to the Flora of the Malay Peninsula is 
an interesting one. The species is closely allied to 6. borneensis, Hook. 
il., from Kinabalu, differing chiefly in the quite entire leaves, rounded 
tips of the petals and entire, not lobed, folds between them. The 
anthers are narrower and more acute. 
The plants collected under the two numbers seem specifcally identical, but 
the specimens of no. 5473 are very much smaller than those of 5479. 
CANSCORA TRINERVIA, n. sp. 
Herba 3-5 poll. alta, caulibus pluribus. Folia glabra ovata vel ovato- 
lanceolata herbacea utrinque acuminata trinervia, 4—1 poll. longa, 
3-3 poll. lata. Flores in axillis superioribus, albis. Calyx tubulosus 
superne angustatus 3 poll. longus, costis 8 elevatis, alternis hifureatis, 
lobis acuminatis. Corolla irregularis alba, tubo quam sepala paullo 
longiore, lobis 4 oblongis rotundatis marginibus erispis, uno multo latiore, 
4 poll. longis. Stamina fertilia 3, antheris oblongis, uno sterili filiformi. 
Stylus sat longus ; stigmatibus 2 linearibus elongatis. 
Gunong Tahan, 5000-5500 ft. Herb by stream ; flowers white. (5507.) 
There are two species of this genus recorded by С. В. Clarke in his 
description of the family in the * Materials for a Flora of. the Malayan 
Peninsula," one of which, С. diffusa, а common Indian species, is 
recorded as belonging to this region only on the authority of а specimen 
collected by Lobb in Singapore and undoubtedly wrongly localised. 
The other, С. pentanthera, С. В. Clarke, ап endemic species, occurs 
usually at high elevations ; it has five complete stamens and a regular 
corolla, while С. trinervia has three complete stamens only and a 
staminode and an irregular corolla.
