(Plate VII.) 
D. ancorarium, sp. n. 
Planta gracilis, in specimine meo cum 5 pseudobulbis, prioribus 
costatis; pseudobulbus iongissimus 17 cm. altus. Folia 3, summo 
pseuclobulbo, late lanceolata,. minute emarginata, 5-7 cm. longa 
Flores racemosi, in pedicel I is circiter 15 mm. longis cum bracteis 
iinearibusl. Racemus inter folia emergens. Flores in specimine 
meo 2. Sepala extra viridescentia cum notat'onibus fuscis, int_us 
flavoviridia. Sepalum dorsale latum, circiter 13 mm. longum; 
sepala lateralia latissima, circiter 15 mm. longa; calcar latum, breve, 
curvum. Petala pallidissima, cum basis fuscis, angustissime lanceo- 
lata, intus concava, circiter 12 mm. longa. Labellum trilobatum, 
brevius quam petala, album; lobi laterales inconspicue lineis pur- 
pureis notati; lobus intermedius fere cordiformis, crassus glaberque, 
supra concavus; lamina cum jugo piano abrupte in lobi intermedii

A slender species, in my specimen with 5 pseudobulbs, 
the older ones ribbed, the newer growths smooth, the 
longest one 17 cm. high. Leaves 3 at the top of the pseu- 
bulb, broadly lanceolate, minutely and obliquely emar- 
ginate, 5-7 cm. long. Flowers racemose on pedicels about 
15 mm. long with linear bracts. Raceme arising from 
between the leaves. Flowers in my specimen 2. Sepals 
outside greenish with brown markings, inside yellowish- 
green. Dorsal sepal broad, about 13 mm. long; lateral 
sepals very broad, about 15 mm. long; spur broad, short, 
curved. Petals very pale, with dark brown bases outside, 
very narrowly lanceolate, concave inside, about 12 mm. 
long. Labellum trilobate, shorter than the petals, white; 
lateral lobes faintly streaked transversely with purple 
lines ; middle lobe almost cordiform, thick and glabrous, 
concave above ; lamina with a flat plate abruptly terminat- 
ing in a curious cup-like fold just above the base of the 
middle lobe. Column white, furnished at the base of its 
foot with an anchor-shaped marking outlined and speckled 
with dark brown dots. 
About five years ago, Dr. II. Flecker, of Cairns, North 
Queensland, sent me a small Dendrolmm plant obtained in 
the neighbourhood of Mount Spurgeon. It had 3 small 
pseudobulbs about 7 cm. high, and appeared to me to be 
probably a juvenile plant, of what species it was impossible 
to say. For a long time it remained quiescent in my bush-
