H. CALOPHrLLUM. 



A small tern sti'iiil Orchid ■« ith a single broad ovate pointed leaf, wliich is most 

 beautifully marbled. Koot, a single ovate bulb, with several Hesliy rootlets above it. 

 Stem solitary, or 8 indies high. Flowers 5 or (J, about an inch apart and an inch 

 long, supported on pedicels (the germ) of the same length, each subtended by a small 

 bract. The upper sepal and the two petals are erect and connivent, being arched 

 over the columu and anther, forming a sort of hood to them, as in some JIabenarius. 

 The lateral sepals are expanded and reflexcd. They vary in colour from white to 

 pink. The lip, which is | inch long and deep violet, is broad, ovate, slightly 

 truncate, wavy at the margin, and produced into a spur behind. A very beautiful 

 little plant. It is found on the limestone rocks which abound in the Tcnasserim 

 Provinces. 



Habexaeia, Wilhl. 



An extensive and widespread genus of terrestrial Orchids. They are found in 

 Europe, Asia, and Africa. Utibenaria hiJ'uUa, or "The butterfly Orchis," as it is 

 called, is sufficiently common in our English woods to be familiarly known to very 

 young botanists. Their general aspect is very similar, wherever found. They aio 

 commonly about a foot or 18 inches high, and have a leafy stem terminating in a 

 spike of sessile white or yellow ilowers, and a large bract under each. The sepals 

 and petals are nearly equal, but the petals, if anything, the smallest. Lip almost 

 always 3-lobed, often with its segments much elongated, or cut into fringes. The 

 root is tuberous ; sometimes one, sometimes two may be found, according as tlic 

 last Tear's tuber has decayed sufficiently to fall off or not. There are IG species 

 enumerated in my list, and, no doubt, there remain many more yet to be iliscovered.

A very remarkable Orchid indeed, found once by me, and once only, in the year 

 1859, far away in the jungles near Ko-txati-ko-ycivn or "99 islands." It is entirely 

 leafless, of the thickness of a small rattan, or, say, the little finger, and scrambles up 

 and over trees to an indefinite length. My specimen was about 30 feet lung, but 

 Lindley .speaks of it (or a similar species) as being " 50 to 120 feet long." The colour 

 of the stem is reddish-brown and the place of leaves is supplied by stitf leathery 

 scales, at long intenals. It supports itself by aerial roots, and its flowers are in 

 racemes, of a yellow colour, and, as far as I can recollect, about 1 inch across. It was 

 in my early days of botanising in Burma that I found it ; I had no drawing materials 

 with me, and I was so loaded with new and strange things, that there was no time 

 to do more than roll it up just as it was, in a coil as one would a rope, take it home, 

 and finally send it to Kew. The structure of the flowers, therefore, is unknown 

 to me, except as I read it in Prof. Eeicheubach's printed notes. I took the plant at 

 the time to be Erytlirurchis scandeiis, Bl. and 1 do not even now know wherein 

 Galeola differs from Enjthiordus.

I had the good fortune to find, in the same jungles, though not on the same 

 occasion, a species of Vanilla which I'rof. Reicheiibacli named after me. Vanilla, like 

 Galeola, has a thick cord-like stem which climbs up and over trees and hangs down 

 in festoons from them. It is leafy, however (ono species excepted), the leaves being 

 ovate, oblong, pointed and very green and fle.shy. It attaches itself firmly to its 

 support by short thick, flefihy roots. I had three species growing for many years 

 in a shady part of my garden in ilaulmain. I erected a large trellis for them which 

 they soon covered with a tangled mass of vegetation. Nothing could be more rampant 

 than their growth. Although I could not distinguish quo from another when out of
