At first sight this species mio^ht be mistaken for M. hrac- 

 tescens ; but its flowers are smaller ; the bracts very small 

 and setaceous, and the lip of quite another form. It has 

 little Jbcauty, and was found in Guatemala by Mr. Hartwcg, 

 by whom it was sent to the Horticultural Society in 184<1. 



13. BRASSIA. 



This genus consists of American Epiphytes, with pseudo- 

 bulbs and a radical spiked inflorescence, of which many species 

 are in our gardens. Its great features are a very dwarf wing- 

 less column, a sessile flat undivided labellum, with two (or 

 occasionally more) short plates at its base, and. a spreading 

 perianth. Recent discoveries have considerably enlarged it, 

 so that from consisting of a single species, as it did when 

 first defined in 1813, or of two, as was the case when the 

 Genera and Species of Orchidacese were published in 1833, 

 we have now fourteen well defined and clearly known. Of 

 these the followinof is an enumeration : 



1. B. Lanceana (Lindl. in Bot. Reg. t. 1/54.); sepalis lateralibus elongatis 



labello oblougo undulato acuminato subrepando vix duplo longioribus : 

 callo baseos simplici canaliculato truncate pubescente dentibus 2 liberis 



membranaceis in fronte. Surinam. A charming species, with 



bright yellow flowers spotted with lively brown, and very sweet-scented. 



2. B. Lawrenceana (Lindl. in Bot. Reg. 1841. misc. 6. t. 18.) ; sepalis late- 



ralibus elongatis labello oblongo apice lanceolato subuudulato plus duplo 



longioribus : callo baseos simpUci canaliculato truncato pubescente. 



Brazil ? This plant is I fear only a variety of the last, and is 



perhaps from the same country, for there is no proof of its being Bra- 

 ziUan, as is stated. The principal differences that distinguish it from 

 B. Lanceana are, the lateral sepals being more than twice as long as the 

 lip, and the want of free extra tubercles in front of the callus at the 

 base of the lip. The flowers are pale yellow, faintly spotted with brown, 

 and very sweet-scented. 



3. B. angusta; pseudobulbis oblongis ancipitibus, foliis binis oblongis sessi- 



libus subundulatis racemi longitudine, sepalis linearibus acuminatis 

 lateralibus caudatis, petahs linearibus acuminatis, labello lineari-lauceo- 

 lato acuminato lamellis baseos connatis pubescentibus antice denticulo 



auctis. Brazil. The first knowledge I had of this plant was 



derived from a specimen sent by Mr. W. Masters of Canterbury, who
