and the more wedge-shaped shorter petals are white deeply 

 tipped with chocolate purple, the tint of which seems to vary 

 in the different varieties we have seen ; the lip is trowel-shaped, 

 three-lobed, ochre-coloured or white, with the whole surface 

 except the margin covered with short purple-tipped papillas 

 papulcB radiantes as Prof. Eeichenbach calls them, ranged 

 in lines ; the ruff or callus at the base consists of nineteen 

 lamellae, sulphur-coloured with brown keels, and the column 

 is yellowish washed with brown and purple. Several varieties 

 have been observed. — Ecuador.

Syn. — Zygopetalum Klabochorum, 



P. Lelunanili, Uchh. f. — This, which is one of the most 

 charming species of Pescatorea, in habit resembles its con- 

 geners, being bulbless, with linear lorate acute leaves, 

 from one to one and a half foot in height, and about an 

 inch broad, the solitary flowers emerging from their axils. 

 These flowers are large, from three to three and a half inches 

 across, and very showy; the sepals and petals are broadly 

 cuneate oblong, white with close curved parallel lines of reddish 

 purple extending nearly to the edge ; and the lip is deep 

 mauve purple, the anterior portion oblong, revolute, retuse, 

 and covered with long bristle-like papillae of a purple tint, 

 the callus or ruff of about eleven ridges being of a chestnut 

 brown colour. It appears to bloom at different times of the 

 year. — Ecuador.

P. Roezlii, Echb. f. — This is a very distinct plant, though 

 allied to P. Bayana. It seems to vary a great deal in the 

 colouring of its large flowers. In the form usually met with 

 the oblong sepals and cuneate obovate petals are white, beauti- 

 fully tipped with violaceous lilac or purplish rose, and the 

 blade of the lip, excepting the callus, is of the same showy 

 colours. — Ecuador. 



P. Eusseliana, Fichb. f. — A large-flowered beautiful and 

 free-flowering species, with broad sepals and petals which 

 are cream-coloured, tipped with reddish purple ; the lip is 

 of the same reddish purple colour, with a yellow ruff or 

 callus having fifteen lamellas with deep crimson purple angles.
