Dendrobium antennatum. 
Lindley in Hooker’s London Journal of Botany 1843, p. 236 ; Bentham Botany of 
the voyage of H.M. Ship Sulphur, 1844, t. 59. 
Glabrous ; leaves alternate, coriaceons, lanceolate, not keeled ; flowers 
several in tlio raceme, greenisb yellow; inner sepals tidce as long as 
the outer ones narrow lanceolate-linear; lateral sepals broadly falcate- 
seinilanceolar, several times longer than the conical-cylindric spur; 
lahellum as long as the outer sepals; its terminal lobe roundish-rhom- 
boid short-acuminate or simply acute, about half as long as the rest of 
the lahellum ; the lateral lobes blunt or rather acute, the whole greenish- 
yellow and streaked with ptxrple veins, the thickened axis towards the 
base and towards the junction of the upper lobe raised into two thin 
plates; the two outer of the three streaks of the upper lobe laminar 
towards the base ; column several times shorter than the labellura ; 
capsule fusiform-ovate, large, the three outer valves forming broad 
longitudinal bauds free and overlapping at their margins. 
New Gxxinea; Hinds. 
This orchid, though not contained in Sir Will. Macarthur’s sending, 
is here inserted, as the writer had an opportunity of examining a living 
plant brought from the Duke of York’s Island (between New Ireland 
and New Britain) by Mr. C. Walter, who while under engagements 
of tlie young ornithologist, Baron A. von Ilucgel, accompanied the 
Rev. Mr. Brown, of the Wesleyan missions, in his recent voyage, and 
obtained also on York’s Island the rare Ba?a Commersoni (R. Br. in 
Horsf. Plant. Jav. Rar. p. 120) and Coccoloba platyclada (F, M. in 
Hook. Bot. Magaz. 5382). 
The leaves and particularly the flowers of our specimen are rather 
smaller than those of D. Tokai ; the sepals are much more unequal, not 
of a pure yellow ; the labellurn is not white and the spur much thinner, 
while the upper not the lower portion of the lahellum is the shortest. 
D. macranthum from Vanicoro is still more distant. The extension of 
the inner bcyon<l the outer sepals occurs however in D, Mirbelianum, 
(Gaudichaud Botuni(pie, Freyccnet Voyage an tour du Monde, pi. 38), 
which together with D. veratrifolium, D. bilobum, Saccolabium fascicu- 
latum and Vanda Iliiidsii was noticed by Lindley from Hinds’s New 
Guinea collection. Dendrobium tridentiferum and D. bifalce and Sacco-
