 M. luteo-alba Turneri, supra. M. Turneri, Hort. 



A handsome species discovered by Linden in 1842 on the Cordillera 

 of Venezuela, near Merida, at 5,000 — 7,000 feet elevation, and 

 subsequently gathered in the same region by Schlim, Wagener and 

 other collectors. We find no record of its first introduction into 

 British gardens.

 Leaves linear-lanceolate, acute, 5 — 8 inches long. Peduncles 3 — 4 inches 

 long, the ovary mottled Avith dull green and crimson. Flowers about 

 1^ inch across vertically ; sepals Ijent forward, linear-oblong, acute, light 

 orange-yellow with a narrow dark red margin and a median red line 

 behind ; petals similar but much smaller ; lip three-lobed, the side lobes

Introduced from Rio de Janeiro to the garden of the Horticultural 

 Society of London at Chiswick, where it flowered in November, 

 1830; a few years later it was gathered by Gardner at Rio 

 Compaido in southern Brazil. Not being a very showy plant it 

 seems to have been generally neglected by horticulturists. We 

 received flowers from Burford Lodge and Glasnevin.
