This is a beautiful species allied to D. Pierardi, 
near which it should perhaps be placed, rather than in 
this division. The flowers are almost transparent, of 
the most delicate pink, and nearly as large as in D. 
moschatum. 
40. D. formosum (Roxb. fl. ind. 3. 485. L. p Sio- Wall. pl. 
as. rar. t. 39. Bot. Reg. 1839. t. 64) ; caulibus tereti- 
bus pendulis pilosis, foliis distichis ovatis apice obliqué 
emarginatis obtusis, racemo brevi terminali 4-5-floro, 
bracteis brevibus ovatis, (floribus maximis), sepalis 
oblongis acutis : lateralibus basi long& productis, petalis 
duplo latioribus acutis, labello obovato dilatato retuso 
cum basi columnz in calcar obtusum connato. — East 
Indies.— —One of the finest of the genus, with very 
large white flowers in terminal racemes. 
41. D. rhombeum (Lindl. in Bot. Reg. 1843. t. 17); caulibus 
teretibus foliosis, foliis lanceolatis acutis, racemis brevi- 
bus 4-floris, sepalis ovalibus obtusis, petalis dupló latiori- 
bus ovatis, labello rhombeo undulato acuto medio pubes- 
cente, columnä utrinque tuberculatà pone basin cornu 
deflexo auctä, antherá pubescente.___ Manilla. This 
species has much general resemblance to D. aureum, 
from which however it differs in having smaller blossoms, 
a labellum without serratures, and the flowers in short 
racemes instead of pairs. Here, as in some other cases, 
the column is furnished, near the base, with a deflexed 
horn lodged in a niche just above the insertion of the 
lip. This is a remarkable process, whose nature requires 
to be investigated. Is it the unguiculus of Blume ? 
42. D. fimbriatum (Hooker. Exot. Fl. 71. Wall. Cat. no. 
2011. L. no. 38); caulibus teretibus pendulis, foliis 
ovato-lanceolatis, racemis lateralibus multifloris, sepalis 
oblongis undulatis patentissimis, petalis majoribus undu- 
latis ciliatis, labello indiviso rotundato convexo fimbriato, 
fimbriis laceris. Nepal, Burma. . Flowers very 
deep yellow, sometimes stained with crimson at the base 
of the lip. It has much the appearance of Dendrobium
