The plant varies very little. There is a very tall form with 
stout stems as thick as the little finger, more terete than usual, 
which occurs in more wooded spots; the leaves of this are usually 
more elliptic than the common form, and it has also a little black 
pubescence on the rhachis and ovary. 
I have once met with a peloric flower in which the lip was narrow 
linear lanceolate-acuminate, with no lateral lobes, and the raised 
median ridge wanting, the edge of the lip being suffused purple. 
2. BROMHEADIA SYLVESTRIS, n. sp. 
Caules erecti, 1-6-pedales, graciles, debiles, complanati, folia 
dissita tenuiora quam in precedente lanceolata, apicibus inæqua- 
liter bilobis, obscure viridia, carinata, circiter 5 uncias longa, 2 
unciam lata, terminalia et basalia ut in palustri sine laminis. 
Racemi 1-2 ad apicem caulis flexuosi iis B. palustris subsimiles, 
bracteis distichis eymbiformibus. Flores quam in B. palustri 
sæpius minores, rarissime visi, aurantiaci, unciam longi. Sepala 
lanceolata acuminata acuta carinata aurantiaca. Petala latiora 
æquilonga obtusiora eodem colore. Labellum quam petala brevius 
trilobum; lobi laterales erecti oblongi obtusi flavescentes, margine 
albo, venis kermesinis ornati,lobus medius ovatus acutus albus 
disco elevato flavo-aurantiaco, linea mediana inter lobos laterales 
elevata flava. Columna gracilis arcuata flava, basi kermesino- 
punctata. Anthera ovata. Clinandrii margo integer. 
Singapore. Kranji, in sylvis densis et in locis umbrosis, hic et 
illie in Singapura sed rarius. 
A very shy flowerer; but distinguished when not in flower by 
the weak stems, often producing leaf-buds instead of flowers, and 
the thin texture of the leaves, which are sometimes quite flaccid, 
instead of being stiff and hard as in B. palustris. Dried specimens 
are not at all easy to distinguish except by the unequal lobes of 
the apex cf the leaves, of which, however, I have also seen traces 
in B. palustris when grown in dense shade. The colouring of 
the flower is unmistakable, and the narrower aeute lip will also 
easily distinguish it.
