52. D. auriferum (L. no. 39) ; caulibiis tcrctibus pcndulls, 

 foliis oblongis obtusis integris, raccmis lateraliljus hori- 

 zon talibus clavatis foliorum longitudine, bracteis cucul- 

 latis dense 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 S-lobed. 



53. D. harhatulum (L. no. 44. JD. chlorops, Lindl. in Bot. 



Reg. 1844. misc. 54) ; caulibus teretibus, floribus laxe 

 corymbosis, pedicellis filiformibus glaucescentibus, sepalis 

 lineari-oblongis, petalis duplo latioribus obovatis, labelli 

 trilobi plani lobis lateralibus nanis acutis intermedio 

 lineari-oj^longo apice paulo 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 vt^as 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) ; caulc 



erecto ramoso folioso tereti glabro, foliis anguste lanceo- 

 lato-linearibus acutis, floribus purpurascentibus ssspius 

 quaternis pedicellatis subspicatis, sepalis lanceolatis acu- 

 tis, labelli unguiculati trilobi lobo medio latiore ovato 

 margine subcrispo lateralibus obtusis subcrispis 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- 

 lique bidentatis, pedunculis lateralibus squamatis 4-floris, 

 floribus concavis subcarnosis, sepalis petalisque subro- 

 tundo-ovatis acutis, labelli trilobi lacinia intermedia ro-
