ragged line interposed on each side of the column between the upper and lateral sepals, as is shewn 

 in the accompanying figure, Xo. 1 ; but 1 have not been able to make out this fact in the few and 

 bad dried (lowers brought under examination. 



The plant has quite the habit of a large BolbophyllunL From a Inrgc creeping scaly riiizoma 

 spring at considerable intervals ovate ps kudo-bulbs, ;it first covered with the ragged remains of the 

 scales out of which tbev originnlly proceeded ; each t-* about two inches long, and bears u single 

 leaf. The leaves are rather less than a fool long, oblong, leathery, deep green, vein less, obtuse, a 

 little downy beneath, will* the channelled footstalk nearly as long as the blade. The hacuhf. is 

 rather shorter than the leaf, erect, proceeding from the base of a pseudo-bulb, pale green spotted with 

 dull purple, with about two sheathing scales below the origin of the first flowers. Each PLOW&R 

 when fully expanded in about an inch long, with the lip and upper sepal placed transversely with 

 respect to the axis of growth. Of the sepal* the upper is triangular, acuminate, nearly plain, dullolrre 

 green, much shorter than the two lateral ones, which are placed below the lip, a little united with 

 each other at (he base, where they arc fixed upon the long foot of the column in such a way as to 

 form a kind of bhmt spur; on the outside they arc very light green, smooth and dotted with light 

 purple ; on the inside they are hair)*, yellowish, and irregularly spotted with bright purple. The 

 PETALS appear to me to be wholly absent ; but iu Dr. WallichV figure they arc represented as two 

 ragged lines. The nnv.nrv i* articulated with a very long foot of the column, horizontal, dull 

 yellow, ihrec-lobcd, the lateral lobe* being falcate and cmarginate. the intermediate otic ovate, with 

 four continuous acute plates, united into pairs, parallel with its margin. The column is short, half 

 round, extended at the base into a long slender curved foot* on which the sepal* and labeltum are 

 inserted : with the two upper angles in front produced into short points. The antiidi is downy, 

 one-celled, with a fleshy cren crest. The pollev-massks are four, on the same plane, the two 

 interior being the smallest, and all consolidated into ;i roundish oval hall, without the slightest trace 

 of a caudicula or gland. 



Fig* 1. of the above dissections represents a flower of this plant much magnified, with the back 

 sepal cut off*

A pretty epiphyte inhabiting the East Indies, and at present known only from a drawing in the 

 possesion of the East India Company, of which, with nil the others forming the wreath before us 

 I havo been permitted to take copies, 



Its stems arc about six inches long, ami arc covered by numerous leaves, so disposed as to 

 arrange themselves in two rows. Each leap is rather more than six inches long, sessile, slightly 

 amplexicaul. oblong-lanceolate, very acute, quite llul and even, and apparently fleshy. The flowers 

 appear in small corymbs, placed on stiff peduncles, from two to three inches long, and springing
