Few countries so rich in Orchids as Borneo have been so much 
neglected in the elucidation of these plants, although a consider- 
able number of the showier kinds have been introduced and 
described in various horticultural periodicals. Unfortunately 
the localities given in these publications are nearly all worthless, 
owing to the desire of the introducers to keep the localities 
secret whence they were procured. I have had the gratification of 
working through the important collections made by Dr. Haviland 
in the neighbourhood of Sarawak, and the plants in this collec- 
tion form the basis of my remarks; to which I have added descrip- 
tion and notes of species collected in Sarawak by Bishop Hose, 
and in Sandakan by Mr. Pryer, together with a few obtained 
from various other collectors and orchid dealers in Singapore, 
and there cultivated in the Botanic Gardens. Many ofthe latter 
are described from living plants, which must be taken into account 
when comparing the descriptions with dried specimens. In the 
list I have incorporated the names of species recorded from 
Borneo which there is reason to believe were really obtained 
there. 
It will be noticed that there is a preponderance of Epidendree, 
due to the prominence of the large genera Eria, Dendrobium, 
and Bulbophyllum. Neottiee are not well represented; but I 
believe that careful searching will produce a considerable number. 
Always difficult to find in the dark recesses of the jungle, seldom 
met with in flower, and difficult to bring home alive, they are 
more likely to be neglected than the more conspicuous epiphytes 
easily brought down ‘and cultivated. 
The most interesting plant in the list is the new genus 
Porphyroglottis, allied to Chrysoglossum, but with the habit of 
Grammatophyllum. 
There are a considerable number of species common to Borneo 
and the Malay peninsula, and very nearly all the Bornean genera 
are represented in the latter region; but certain genera, such as 
Phalenopsis, Platyclinis, and Cypripedium, are more abundant in 
Borneo, probably from local causes. 
Taking it as a whole, the Malayan region, from the Isthmus
