PAPHINIA. 79 



An attractive species originally imported from Brazil by Messrs. 

 Loddiges, in whose nursery it flowered in June, 1838. As in the 

 case of most of the earliest imported orchids from Rio de Janeiro, 

 no locality was recorded, although it is certain that the plant was 

 gathered at no great distance from that city. We received materials 

 for description from Burford Lodge and from Glasnevin.

The type species, like many more of the South American Vande^, 



was originally described and figured as a Maxillaria. In his revision 



of that genus in the Botanical Register of 1343, Dr. Lindley 



removed it from Maxillaria on account of the different structure of 



its pollinary apparatus : in Maxillaria the pair of double pollen 



masses are sessile or nearly so, on a crescent-shaped gland; in 



Paphinia they are connected with a small roundish gland by a long 



slender caudicle (stipes). This is an important difference from a 



botanical point of view, and justifies the separation of Paphinia 



from Maxillaria; but in Lycaste we find a similar condition of 



things, and on that ground chiefly Mr. Bentham reduced Paphinia 



to a synonym of Lycaste; but here again other characters have 



to be taken into account by the systeraatist : in Lycaste the scapes 



are with one exception* one-flowered, and always erect ; in Paphinia 



they are oftener two or more flowered and pendulous, and the 



flowers strikingly different in colour; and more important than this 



is the different form of the labellum in the two genera : in Paphinia 



this organ, as will be seen from the description of the species that 



follow, has quite a complex structure; in Lycaste it is comparatively 



simple. On these grounds we have retained Lindley's genus Paphinia, 



not only for garden use, but also if merged into Lycaste — itself a 



very natural genus — the homogeneity of the latter would be greatly 



impaired,
