864 ORCHIDES. ^. vanda. 



Herbae epiphytae Asiae tropicae. Folia coriacea, disticha, apice obliqua. 



Flores saepius racemosi, conspicui. Pcdunculi lalerales. 



The limiis of ihis genus are very difficuit to ascertain ; ihey are here deflned by 

 a saccaie or calcarate lip continuous with the column, a truncate rosiellum, and two 

 or four polien-masses attached lo a broad caudicle having a large circular gland. It 

 is very near Luisia, which is betler knovvn by iis habit than by any very satisfaclory 

 peculiarity of structure, except having a very shori broad caudicle, and tbin gland. 

 Probably V. Lowei at least will hereafter be seperated, if oiher sptcies agreeing with 

 in its long drooping racemes and simple unguiculate lip should be discovered. The 

 genus, as it now siands, may be divided into the foUowing seclions.

the base, with a strong tooth at or above its middle, 



Pollen-masses four.

 This flne species, ihe type of ihe genus, is readily known by its tesselated flowers 

 and blue lip, the lateral lobes of which are sharp-pointeii, and as long as the column.
