linearibus contortis duplo longioribus, labello oblougo 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 (Gaudicli. Voyage, t, 38.) ; foliis ovato-oblongis obtusis, 



racemis ovatis . longe pedunculatis, sepalis ovato-lanceolatis acutis erec- 

 tis, petalis spatliulatis iinguiculatis 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. c. L.) ; foliis oblongis obtusis amplexicaulibus 



9-1 1-nerviis, raceme terminali clongato multilloro, sepalis undulatis 

 acutis, petalis spatliulatis obtusis planis vix duplo longioribus, labello 

 oblongo obtuso menibranaceo venis tribus elevatis per axin duabusque 

 iiiinoribus lateralibus : lobis lateralibus nanis obtusis intermedio ob- 

 lougo 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. 



A. D. macranthum (A. Rich. Sert. Astfolab.p. 15 t. 6.) ; foliis ellipticis apice 

 obliquo subbilobis, racemo longipedunculato versus apicem monophyllo, 

 sepalis ovato-lanceolatis, petalis paulo longioribus iinguiculatis lanceola- 

 tis acutis, labello lanceolato trilobo per axin tricariuato 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
