expanding to a diameter of about 1 in., all the segments except the labellum 
incurved. Dorsal sepal 33 lines broad, the lateral ones much broader from 
being adnate at the base to the whole length of the elongated base of the 
column, speckled with purple spots in irregular lines, spur or pouch scarcely 
perceptible. Petals like the sepals, but only about half as broad. Labellum 
on a short broad claw attached to the end of the column ; lateral lobes erect, 
84 lines high, tapering to blunt points, with 5 longitudinal dotted lines ; middle 
lobe rather longer than broad; the end rounded, emarginate, 6 lines broad, 
tapering downwards. Disk plates between the lateral lobes and extending 
somewhat higher up, 2 outer ones very prominent, those between them not 
half so high, all with irregular margins. Column very short and broad, mostly 
green. Stigma deeply sunk. Rostellum with white border. Anther-lid flat, 
green. Pollen-masses nearly globular, amber colour. 
Hab. : Douglas Harbour, New Guinea, May, 1898. 
D. D’Albertisii, Reichb. f. Erect stems numerous, forming dense masses upon 
the trunks and branches of trees, 6 to 12 in. or in some localities higher, the 
lower part obtusely 4-angular, and 4 to 9 lines in diameter, the upper portion 
tapering upwards, somewhat flattened and leafy. Leaves lanceolate, the lower 
ones 3 to 4: in. long, gradually decreasing in size to the apex of the stem, where 
they are often under Lin. long, thick and distichous. Peduncles numerous from 
the axils of the underleaves. Bracts small, 2 or 3,empty. Pedicels with short 
ovary 12 to 15 lines long, white. Dorsal sepal curled, lateral ones recurved and 
sometimes slightly curled, white, about 9 lines long. Petals erect, about 1% 
in. long, 1 to 1} lines broad, green in the upper half, white in the lower, usually 
strongly curled, spur narrow. Labellum long as the sepals, attached to the 
base of the column by a short narrow claw; lateral lobes erect, tapering down- 
wards and forming a cuneate base to the labellum above the truncate yellow- 
stained end, obliquely streaked with purple; middle lobe ovate-apiculate, purple 
lined. Disk plates 2, with sometimes jagged margins. Column white, with 
rather thick wings ending in a tooth on either side of the anther. Anther- 
lid flat, densely tomentose in front. Rostellum white infront. Pollen-masses 
oblong, amber colour. 
Hab. : Holdicott Bay, New Guinea. The above description was written from plants 
freshly gathered at their native habitat, and may therefore differ in some slight degree from some 
of the descriptions given, which have been obtained from dried specimens or p!ants in cultivation. 
SPATHOGLOTTIS, Blame. 
S. papuana (n. sp.) Pseudobulbs 1} to 8 in. high, obtuse conical, crowned 
by grass-like plicate leaves, their sheaths forming a thin stem of 2 to 5 in.; the 
lamina 12 to 15 in. long and 1 in. broad in the centre usually, but in some 
localities much larger, tapering to long fine points. Scapes 15 in. or more 
high, empty lower bracts closely sheathing the stem, those subtending the 
edicels loosely spreading, broadly ovate. Pedicels with ovary about 14 in. 
ong, very pale-purple. Flowers about 6 in terminal racemes, varying on, 
different plants from a magenta or dark-purple to nearly white. Sepals 
and petals about 8 or 9 lines long, oblong-ovate. Labellum nearly as long; 
lateral lobes 83 or 4 lines long, salmon-coloured, faleate-cuneate very near the 
base with a minute lobe at the end of each in front; middle lobe on a long 
slender claw, broadly-cordate, nearly white; disk plates 2, erect, spreading, 
vather jarge and a smaller one at the top of the claw. Column enlarging 
upwards, incurved, pink; anther-lid and rostellum beaked. 
' Hab. : Along the coast of Porlock Bay. In the crevices and on the face of rocks in the leaf- 
mould which is often found to collect in such situations. 
There are three forms of this species, only differing in colour of flower: 
one nearly white with only the least tinge of purple; another, pale-purple ; 
and another whose flowers are deep purple or magenta. These are frequently 
met with growing together on the same rock; therefore the difference of colour 
cannot be due to situation or soil, neither is it due to age, for the colouring is 
the same from the opening of the buds in each form.
