Var. OrpIANA, var. nov., with the leaves bright velvety green, 
with pale veins, is obtained in Pulau Tinggi. It is very 
much rarer than the dark red form. 
Var. Concotor, var. nov. Leaves deep olive green with pink 
midrib. I received this from Saigon from Dr. Bronsmiche. 
Var. Orterz, Ridl. H. Otletw, Rolfe, in Ilustr. Hortic., 
Xxxvili. (1891) p. 31, t. 124, is a narrow-leaved form which 
Sometimes appears with the commoner forms. 
The well-known locality for this orchid is on the islands lying 
off the east coast of Johore. On the nearest, Pulau Tioman, I 
have found it growing on rocks in the streams. The natives, 
who deal in it and import it in large quantities, call it “ Daun 
Low,” i.e. Sir Hugh Low’s leaf. 
The flowers, which are pure white, except for the conspicuous 
yellow anther-cap and apex of the column, are unusually showy 
for this section of Nevttew. I have seen them fertilized by a 
butterfly, viz., Plesioneura asmara. This insect, which has very 
long legs, settled on the spreading sepals and lip, and plunged 
its proboscis into the opening of the spur between the lip and 
column, which are closely appressed together. While thus 
engaged one of its left legs struck against the viscid disc of 
the pollinia, which it withdrew, and which remained adhering
