Columna auriculata vel aptera, Labellum sessile, vel saKeni haud 

 imgue lineari instructum. Sepala subaequalia, radianlia, lateralibus om- 

 nino sessilibus, aut parum unguiculata. Flores speciosi. 



The species ihus separated from Wyanlhium approach that seclion by 0. auro- 

 purpureum and ils allies, but they never have in the same degree that manifest pro- 

 iongation and paralleiism of the lateral sepals which characterises Myanihium . as is 

 readily seen upon inspecting ihe expanding llower-buds, All the species are hand- 

 some, wiih large yellow or white flowers; some preeminently so. In the first divi- 

 sion the sepals and petals are narrow , and stand wide apart when expanded ; in the 

 second division, in consequence of their increased brcadtli, ihose organs almost or 

 quiie overlap each othcr.

Wild in Peru — W. Lobb; in Venezuela— Funck and Schlim, 1430, 

 Stem six leet high.— F, and S. Flowers golden-yellow, marked with purple.— Rb. 

 A noble species wiih a siifT much-branched panicle of fiowers , the stalks of which 

 are twice as long as tiie internodes, Each flower measures about iwo inches in dia- 

 meter. Thc bracis are almost equal to the iniernodes in some cases, Mr. Lobb's 

 Peruvian specimcns have a morc compact iuflorescence and largcr flowers than ihose 

 from Venezuela.
