65. D. Mirhellanum (Gaudich. Voyage, t. 38.) ; foliis ovato- 

 oblongis obtusis, racemis ovatis longe pcdunculatis, sopa- 

 lis ovato-lanccolatis acutis erectis, pctalis spatiiulatis 

 unguiculatis obtusis longioribus, labelli trilobi ovato- 

 lanceolati subsessilis lobis lateralibus rotuudatis inter- 

 medio lanceolato imdulato acuto, lineis tribus elevatis 



lateralibus versus basin duplicibus. New Guinea. 



The racemes, including their peduncle, are more than a 

 foot long. The petals are an inch and a half long. 



6Q. D. veratrifoUum (Lindl. in London Jour. Bot. 2. 1^35.) ; 

 foliis oblongis obtusis amplexicaulibus 9-11-nerviis, 

 racemo terminal! elongato multifloro, sepalis undulatis 

 acutis, petalis spathulatis obtusis planis vix duplo longio- 

 ribus, labello oblongo obtuso membranaceo venis tribus 

 elevatis per axin duabusque minoribus lateralibus : lobis 

 lateralibus nanis obtusis intermedio oblongo undulato. 



JVeiv Guinea. 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. 



67. D. rnacranthum (A. Rich. Sert. Astrolab. p. 15. t. 6.) ; 

 foliis ellipticis apice obliquo subbilobis, racemo longi- 

 pedunculato versus apicem monophyllo, sepalis ovato- 

 lanceolatis, petalis paulo longioribus unguiculatis lanceo- 

 latis acutis, labello lanceolato trilobo per axin tricarinato 

 lacinia intermedia acuminata lateralibus nanis rotun- 



datis. Vanikoro. The stem is described as two 



feet and more high ; the leaves from three to four inches 

 long, the raceme about a foot long, the flowers three 

 inches in diameter. It is very near D. veratri folium, 

 but difi'ers in having much shorter petals, and a very 

 acute lip. 



08. D. antennatum (Lindl. in London Journ. Bot. 2. 235) ; 

 foliis lanceolatis carnosis oblique, emarginatis racemo 

 oppositifolio brevioribus, sepalis acuminatis, petalis linea- 

 ribus duplo longioribus reflexis, labello trilobo venis 

 5 elevatis rectis per axin ; lobo medio ovato acuto piano 



3-costato. New Guinea. This is a most curious 



thing, with flowers having their long horn-like petals 

 directed backwards, and their sepals forwards. The 

 petals are two inches long, and scarcely half a line wide.
