linearibus coutortis duplo longioribus, labello oblongo apice crispo per 
axin lineis 3 elevatis intermedia apice flexuosa aucto. 
A native of Manilla, whence Mr. Cuming sent it to Messrs. 
Loddiges. It has large flowers, with yellowish green sepals, 
rolled back at the points, very long deep purple twisted petals, 
and a paler purple lip, with three elevated lines along the 
middle, and a few small tubercles near the apex (fig. 2.). The 
column (fig. 1.) is short and somewhat pouched at the base, 
in consequence of the lip being adherent to it at that place. 
The plant is five feet high. It flowered at Hackney in Octo- 
ber last. I have wild specimens from Mr. Cuming ; but they 
are not nearly so handsome as that now figured from Messrs. 
Loddiges. 
2. D. Mirbelianum (Gaudich. Voyage, t. 38.) ; foliis ovato-oblongis obtusis, 
racemis ovatis longe pedunculatis, sepalis ovato-lanceolatis acutis erec- 
tis, petalis spathulatis unguiculatis obtusis longioribus, labelli trilobi 
ovato-lanceolati subsessilis lobis lateralibus rotundatis intermedio lan- 
ceolato undulato acuto, lineis tribus elevatis lateralibus versus basin 
duplicibus. 
A native of New Guinea, whence I have specimens from 
Mr. Hinds, Its racemes, including their peduncle, are more 
than a foot long. The petals are an inch and half long. 
Gaudichaud’s figure is not a good one. 
3. D. veratrifolium (Lindl. 1. e. L.) ; foliis oblongis obtusis amplexicaulibus 
9-1 1-nerviis, raceino terminali elongato multifloro, sepalis undulatis 
acutis, petalis spathulatis obtusis planis vix duplo longioribus, labello 
oblongo obtuso membranaceo venis tribus elevatis per axin duabusque 
minoribus lateralibus : lobis lateralibus nanis obtusis intermedio ob- 
longo undulato. 
Another species from New Guinea, where it was found by 
Mr. Hinds. It is a most beautiful plant, with racemes a foot 
and a half long, loaded with flowers, whose spatula-shaped 
petals are an inch and more in length. The inflorescence is 
very loose in this ; in D. Mirbelianum it is far more compact. 
4. D. macranthum (A. Rich. Sert. Astrolab. p. 15 t. 6.) ; foliis ellipticis apice 
obliquo subbilobis, racemo longipedunculato versus apicem monophyllo, 
sepalis ovato-lanceolatis, petalis paulo longioribus unguiculatis lanceola- 
tis acutis, labello lanceolato trilobo per axin tricarinato lacinia inter- 
media acuminata lateralibus nanis rotundatis. 
A native of the island of Vanikoso. The stem is de- 
scribed as two feet and more high ; the leaves from three to 
four inches long, the raceme about a foot long, the flowers
