Central Madagascar, Baron no. 4334. 



This is a very remarkable specieSj allied most closely to i. 

 longicaidisy Kidl. Like that species it has a tall slender stem 

 hardly at all dilated into a pseudobulb, but covered witli a number 

 of loose whitiah membranous sbeaths, whicli in tliis species do not 

 overlap, there being a short but distinct space between each 

 sheath. The sheaths are minutely dotted. The leaves, usually 4 

 in number, at the top of the stem, are a little separated from each 

 other, and seem less thin in texture than those of i. longicaiilis. 

 The scape rises to a considerable height and is usually flexuous j 

 numerous bracts are scattered throughout its whole length. The 

 flowers are chiefly remarkable for the shape of the lip, which 

 recalls somewhat that of L, crenulata^ LindL, having a long 

 narrow base ending in a bilobed lamina, the ends of the lobes of 

 which are denticulate. The claw lies parallel to the column, 

 and at the bend there is a kind of rhombiform depression formed 

 by two low ridges which run towards each other and almost 

 meet. Down the middle of this depression run two veins slightly 

 raised and sinuous. This rhombiform depression is, in the dry 

 plant, of a darker colour than the rest of the lip. The stems of 

 the plant, which is doubtless terrestrial, grow close together. 



LiPARis LONGTCArLis, BidL, was obtained at Ankeramadinka 

 by Dr. Fox ; and L. plavescens, Lindl,^ at Ambatovory.
