useful plant for exhibition, on account of its continuing in 

 bloom so long. 



0. Humeanum. — A very pretty novelty, named in honour 

 of the late W. B. Hume, Esq., in whose collection it flowered 

 for the fii'st time ; sepals yellow, striped with bars of cinnamon 

 brown ; petals white, with three sepia blotches at theii' base ; 

 lip white. Dr. Reichenbach supposes this to be a cross be- 

 tween 0. cordatum and 0. Rossii. 



0. Insleayi. — This grows in the same way as 0, grande ; 

 the flowers are brown, yellow, and orange, and are produced 

 on a short spike at different times of the year, lasting in 

 beauty three weeks. Native of Mexico. 



0. Imlemji splendens. — In this variety the sepals and petals 

 are rich shining brown tipped with yellow ; the lip is large, 

 yellow, and spotted with purple. A very fine form introduced 

 from Mexico. 



0. Kramerii. — This is a rather pretty species, and seems to 

 be related to 0. citrosmum, though having a very different 

 appearance. The pseudobulbs are somewhat flat, with sharp 

 edges, in some specimens almost spherical, in others ovate, 

 and pale green in colour, bearing, as far as I am aware, a 

 single leaf only. The spikes are freely produced from the 

 base of the bulbs, and are pendulous, bearing several flowers 

 a Httle less than those of 0. citrosynum ; the sepals and petals 

 are strap-shaped and obtuse ; the lip somewhat reniform, and 

 deeply notched in front. The whole flower is of a charming 

 violet colour, the lip, in addition, being marked and spotted 

 with yellow and purple, with two lines of rich dark brown near 

 the column. It is a good addition to this numerous family, 

 and should be grown in peat and sphagnum moss, and will, 

 Hke 0. citrosmum, require a little more warmth than the 

 generality of the genus. Yeiy rare. Native of Costa Rica. 



0. IcEve. — A pretty species, which will take the very coolest
