COLLECTIONS FROM CHRISTMAS ISLAND. 359 
alta.  Pseudo-bulbus ovoideo-elongatus, diphyllus. Folia anguste 
linearia, obtusa, basi attenuata, 3-43 poll. longa, 2-3 lin. lata. 
Spice laterales, brevissims, subcongeste, ovoidee, j-1 poll. 
longe, bracteis ovato-lanceolatis, floribusque subsessilibus minu- 
tissimis. Sepala ovato-oblonga, obtusa, 4 lin. longa, trinervia. 
Petala sepalis subsimiles, minora, uninervia. Labellum ovatum, 
subconcavum, integrum, obtusum, trinervium, basi contractum, 
sepalis paullo brevius. Columna brevissima. | Capsula fusiformi- 
oblonga, 23 lin. longa.—From high tree-trunks. 
A markedly distinct species, though its relationship to P. con- 
tracta, Miq., may be closer than can be determined from Miquel’s 
imperfect description. 
Dorrrrs, sp. n.? (specimina fructifera tantum adsunt).—On 
iree-trunks on the ridge or highest part of the hill above Flying- 
Fish Cove. 
PALME. 
DrpyMOSPERMA, sp.— On sea-shore. 
There are good specimens of this palm or palms, though the 
fruit is wanting; but there isa little uncertainty about the leaves 
belonging to the same species as the inflorescence. Except in size, 
it does not differ materially from D. porphyrocarpa. Mr. Lister 
appears to have been of the opinion that the specimens represent 
two species; it seems probable, however, that they are male 
and female of the same species. 
PANDANEB. 
PANDANUS, spp.—There are incomplete specimens of three 
species in the collection, one of which, having thin, almost flaccid 
leaves, is said to form a thicket some 10 feet high on the edge of 
the shore. 
CYPERACEE. 
FiMBRISTYLIS cymosa, R. Br.— Java to Australia and the 
Sandwich Islands ; but, as understood by some botanısts, it has a 
much wider range.
