The racemes, including their peduncle, are more than a 
foot long. The petals are an inch and a half long.

—-— New 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. macranthum (A. Rich. Sert. Astrolab. p. 15. t. 6.) ; 
foliis ellipticis apice obliquo subbilobis, racemo longi- 
pedunculato versus apicem monophyllo, sepalis ovato- 
lanceolatis, petalis pauló longioribus unguiculatis lanceo- 
latis acutis, labello lanceolato trilobo per axin tricarinato 
lacinià intermedià acuminatä lateralibus nanis rotun- 
datis. Vanikoro.— —'lhe 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. veratrifolium, 
but differs in having much shorter petals, and a very 
acute lip. 
68. D. antennatum (Lindl. in London Journ. Bot. 2. 235) ; 
foliis lanceolatis carnosis obliqué emarginatis racemo 
oppositifolio brevioribus, sepalis acuminatis, petalis linea- 
ribus dupló longioribus reflexis, labello trilobo venis 
5 elevatis rectis per axin ; lobo medio ovato acuto plano 
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.
