D. auriferum (L. no. 39); caulibus teretibus pendulis, 
foliis oblongis obtusis integris, racemis lateralibus hori- 
zontalibus clavatis foliorum longitudine, bracteis cucul- 
latis densé imbricatis, sepalis petalis labelloque lineari- 
lanceolatis conniventibus acuminatissimis. —— China. 
— — Stem slender, throwing out very long roots from its 
sides. Leaves oblong-lanceolate. Flowers about an inch 
long, bright yellow, arising from short broad imbricated 
bracts, which are much longer than the spaces between 
them. Known only from a drawing in the possession 
of the Horticultural Society. 
B. Lip 3-lobed. 
53. D. barbatulum (L. no. 44. D. chlorops, Lindl. in Bot. 
Reg. 1844. misc. 54) ; caulibus teretibus, floribus laxé 
corymbosis, pedicellis filiformibus glaucescentibus, sepalis 
lineari-oblongis, petalis duplo latioribus obovatis, labelli 
trilobi plani lobis lateralibus nanis acutis intermedio 
lineari-oblongo apice pauló latiore basi villoso, cornu 
brevi conico.——Bombay.——A species with the habit 
of D. Heyneanum. It has small flowers of a pale nankin 
colour, while the base of the lip is a light pea green; 
this gives the flower the appearance of having a green 
eye. When dried the parts of the flower become ex- 
tremely thin and difficult to examine; and I was thus 
led to suppose that the lip was undivided. I have how- 
ever ascertained that it is really three-lobed, and that my 
D. chlorops is the same species, more correctly defined. 
54. D. lancifolium (Ach. Richard Sert. Astrolab. t. 8) ; caule 
erecto ramoso folioso tereti glabro, foliis angusté lanceo- 
lato-linearibus acutis, floribus purpurascentibus sepiús 
quaternis pedicellatis subspicatis, sepalis lanceolatis acu- 
tis, labelli unguiculati trilobi lobo medio latiore ovato 
margine subcrispo lateralibus obtusis suberispis planis. 
Moluccas-—-—Only known to us by M. Richard's 
description. It is a branching species, having little 
resemblance to the plants here placed near it. 
55. D. bicameratum (Lindl. in Bot. Reg. 1839. misc. 85); 
caulibus fusiformibus, foliis lineari-lanceolatis apice ob- 
liqué bidentatis, pedunculis lateralibus squamatis 4-floris, 
floribus concavis subcarnosis, sepalis petalisque subro- 
tundo-ovatis acutis, labelli trilobi lacinià intermediá ro-
