Callleya Walkeriana Gardn. Herb. Fl. Bras. 5200, 

 Hab. On the siem of a tree overlianging a smaii siream , which falls into the Hio 

 San Fraticisco , beyond the Diamond district , Brazii. — The flowers of this very flne 

 species measure about 4 ' in diam. Is is nearly related to C. superba (Schomb. in 

 Lindl. Sert. Orcb. t. 22), but is readily distinguished by its much shorter pseudobulbs 

 and smailer leaves, by ihe larger and more rotund middlc lobe of the labellum, but 

 particularly by the obiiquely truncated lateral lobes, which envelope only the lower 

 half of the broadly winged column , and not the whole of it. as in C. superba. — 

 The specific name will serve lo commeraorate the services of Mr. Edward Walker, 

 who accompanied nie as assistent liuring the last two years of my travels is Brazil, 

 and by wlu)se activiiy and intelligence I was enabled to make many adriitions to my 

 coliections, which raight otherwise have escaped my notice , of wbich Uie present 

 plant is as example,
