OECHIDS OF MADAGASCAR. Il7 



It ia clear from this collection that mucli yet remains to be 

 done in the island, even in the best-worked localities, and indeed 

 there are still several species known only from Tbouars's collec- 

 tions, tbat are not represented in the berbaria of this country. 



I bare incorporated also wnth the account of these plants some 

 notes and descriptions of other new and interesting species recently 

 received from Mr. Baron in Central Madagascar.

Allied to _B. Baronii^ Eidl., but a larger plant, llowers bigger 

 and fewer; lip thin, -with tbe edges curled in beneath, and a 



bilobed apex.

Central Madagascar, Baron no. 4471. 



This species is allied to B. se7/cheUarum,'Reichh. f., differing in 

 its smooth lip &c. The lip is ovate or almost ovate-lanceolate, but 

 in the natural state the margins are so much curled in on the 

 underside that it appears to be hastate. The texture is thin, and 

 it appears to be of a reddish hue, while the rest of the flower seems 



to have been pale coloured.
