had received it from Brazil ; at that time I took it for a starved specimen 

 of B. Lawrenceana. Since that time it lias flowered in the garden of 

 the Horticultural Society, with the same pecnliarity of structure ; and 

 hence I conclude it to be a distinct species. It is readily known by its 

 having extremely narrow sepals and lip, which are of a pale dull yellow, 

 with little marking, except a few brown spots at the base of the sepals, 

 petals, and lip. In this respect it varies, for in some cases the spots at 

 the base of the petals are few and distinct, in others they are run toge- 

 ther into one brown stain. 



B. macrostachya (Lindl. Sertum. Orch. t. 0.) ; pseudobulbis compressis 

 margine obtusis 2-3-phyllis, scapo nutante multifloro, sepalis linearibus 

 acuminatis lateralibus longissimis, labello oblongo-lanccolato acuminato 

 petalis longiore : lamellis baseos liberis villosis dentibus tribus liberis 



in fronte. Demerara. No species can be compared with this most 



graceful and brilliant plant, whose long nodding racemes of flowers bend 

 gently over the rich and verdant foliage, while the slender sepals are so 

 long, so light, and so delicate as to be agitated by every impulse given 

 them by the air. They are of a clear golden yellow, slightly spotted 

 with brown, and many degrees darker than the lip. 



B. caudata (Lindl. in Bot. Reg. t. 832. Epidendrum caudatum, L. 

 Malaxis cmdata, W.) ; pseudobnlbis compressis margine aciitis, scapo 

 erecto, sepalis ovato-linearibus acuminatis lateralibus longissimis, labello 

 ovato acuminato petalorum longitudine, lamellis baseos liberis villosis 



denticulis 2 liberis in fronte. West Indies. Very nearly allied to 



Br. macrostachya, from which it is distinguished by its pseudo -bulbs 

 being acute at the margin, not obtuse, by its flowers being smaller, 

 greener, and much more mottled with deep brown, and by its labellum 

 being ovate, acuminate, and the same length as the petals, not oblong- 

 lanceolate, and longer than them. The little free teeth, too, in front 

 of the calli at the base of the lip, are mnch smaller. 



B. bidens ; pseudobulbis angustis ancipitibus, foliis oblongo-lanceolatis 

 scapo stricto multifloro cequalibus, sepalis acuminatis lateralibus labello 

 duplo longioribus, labello rhombeo undulato petalis breviore : lamellis 



baseos Irevibus rectis appendice membranacea biloba in fronte. ? 



The native country of this species is unknown. I had it from the col- 

 lection of Mr. It. Harrison in 1837. It is allied most nearly to B. cau- 

 data, from which it differs in the form of its lip, and in having two large 

 teeth connected at their base in front of the calli, which are quite smootli. 

 The lip is spotted with brown on a yellow ground. The sepals and 

 petals appear from the dried specimen to be unspotted. 



B. cochleata (Knowles & Westcott, Floral Cabinet, t. .53.) ; sepalis peta- 

 lisque subsequalibus linearibus acimiinatis, labello elongato cochleato acu- 

 minato. Demerara. Now known only from the above figure. 



We have seen no specimen. Possibly it is the B. Henchmanni of Mr. 

 Loddiges' catalogue, or his B. cuspidata, (no. 1467), both of which are 

 unknown to me. 



B. verrucosa (Lindl. in Bot. Reg. 1840. misc. G6. Bateman Orch. Mex. 

 & Gnat. t. 22.) ; foliis scapis gracilibus duplo brevioribus, sepalis late- 

 ralibus acuminatis labello unguiculato obovato apiciUato verrucoso plus 

 duplo longioribus ; lamellis baseos liberis villosis apice recurvis. •
