excursion up tlie river Parahiba in search of Zygopetalum Meleagris. 

 He sent a plant to Mr. George Wailes_, of Newcastle-on-Tyne, 

 wliich flowered in 1849, on which occasion it was named Warrea 

 Wailesiana by Dr. Lindley. It was afterwards detected in the 

 province of Bahia by Porte, one of M. Linden's collectors ; and it 

 has recently been sent to Europe by Binot, a French collector 

 residing at Petropolisj on the coast-range near Rio de Janeiro. 

 Our description was taken from a plant in the Royal Gardens at 

 Kew ; it is unquestionably one of the most attractive species in 

 the section to which it belongs (Warscewiczella).
