832 MR. H. N. RIDLEY ON THE GENUS BROMHEADIA. 
Bromheadia palustris is very common in Singapore, growing 
usually among the ferns and long grass, in open districts, rarcly 
in shady or damp places. It is distributed over the whole of the 
peninsula, from Siam southwards, and in the Malay Islands as 
far east as the Philippines. 
B. sylvestris, n. sp., is a closely allied plant to this, and, like it, 
is terrestrial. In the dry state it is not at all easy to distinguish 
it. Itis usually a larger plant, weaker, with thinner, less coria- 
ceous leaves, and slender stems, growing in tufts and very tenacious, 
with numerous roots. It frequents the more open damp jungles, 
where, however, it seems rarely to flower. It is generally easy 
to distinguish living plants even when out of flower, and though 
I have seen a large number of plants, I have but seldom seen the 
flowers. The flowers are of a beautiful apricot-yellow, as large as, 
or larger than, those of B. palustris, and were it more floriferous 
would be well worthy of cultivation. The lip is narrow, with the 
lateral lobes erect, beautifully veined with dark crimson, the in- 
termediate line bright yellow. The middle lobe is ovate-acute, 
the edges white, the central bar of the lip ending upon it in the 
form of a bright orange raised lump. The sepals and petals are 
somewhat narrower than in the preceding species, bright apricot- 
yellow. The column yellow, with pink stains at the base. 
The two epiphytic species are B. alticola, n. sp., and B. apo- 
roides, Reichb. f. The first of these is not rare in Singapore, but 
very difficult to procure. It frequents the loftiest and most in- 
accessible trees, usually Dipterocarpeæ, growing on the highest 
branches or on the trunk, where it forms masses of four or five 
feet in diameter. The stems are very numerous, about two feet 
high, flattened and leafy. The leaves are narrower and longer 
than in B. palustris, stiff, spreading, and unequally bilobed at 
the apex; they are articulated with the sheath, so that in drying 
they usually fall off. The raceme is not preceded by a long 
leafless portion, but rises directly from the leafy part of the 
stem ; it is often branched, or rather short lateral racemes arise 
from the base. The rhachis is flattened and flexuous, with very 
large cup-shaped bracts. The flowers are smaller than those 
of B. palustris, sweetly scented, and quite as fugacious; 
they open singly in the early morning and perish when the 
sun is well up. In this plant, as in the others, the raceme itself 
lasts a very long time and at intervals produces one flower, so 
that the lower bracts are brown and dry before the raceme has
