§22 ON THE MONOCOTYLEDONOUS PLANTS OF NEW GUINEA. 
while a figure of a plant in Rumphius, from Amboina, seems to be 
intended to represent it. Among the Orchidee several interesting 
novelties are to be found, epokacnn the curious Appendicula repre- 
sented on Plate 270, and some very beautiful species of Dendrobium, 
Sete worthy of cultivation. The Apostasiacee are dae peeress by a 
and striking species of Wiasieta ia, with n leaves, and a 
tall epike of yellow flowers. The difficult order of Poakahiin coal 
to be strongly developed in New Guinea, and several curious species 
of Pandanus and F'reycinetia have been obtained. 
Among the already described species are several till now in- 
sufficiently known. Coelogyne Rumphii was described by Dr. Lindley 
from a figure by Rumphius, and it has not been seen, so far as Tam 
aware, since his time. The Dendrobium — iosum of pate ae . 
la Coquille’ appears no t to have been met with a until n 
and Mr. Forbes’ specimens show that it is not a Dina biti te an 
Eria. The singular and aberrant Dendr ae longicolle Lindl., 
pescribed from a plant sent from Singapore by Cuming and 
flowered by Loddiges in 1840, now reappears in New Guinea.

New Guinea, I have not seen. From the deser ription it seems to

Hamadryas has no wings, nor is the rachis distinctly angled.
