0. Humeaillllll, Kchb. f. — A very pretty Orchid, supposed 

 to be a wild cross between 0. cordatum and 0. Rossii. It is 

 named in honour of the late W. B. Hume, Esq., in whose 

 collection it flowered for the first time. The inflorescence is 

 two-flowered; the flowers have the sepals triangular acuminate, 

 keeled behind, yellow striped with bars of cinnamon brown, 

 the oblong acuminate crispulate petals white, with three sepia 

 brown blotches at their base, and the cordate-ovate acute crenu- 

 late lip white, with a two-lobed yellow callus striped with red 

 on its disk. — Medico .

 leaves, and at their base an erect scape bearing some eight or 

 ten flowers each three inches across, the oblong slightly wavy 

 sepals and petals being of a pale yellow thickly transverse- 

 blotched with rich chestnut brown ; the lip is narrow obovate 

 retuse, smaller than that of 0. grande, bright yellow with a 

 row of crimson spots around the margin. It is further distin- 

 guished by the presence of a pair of red subulate horns or 

 cirrhi on the column. The flowers are produced at difi'erent 

 times of the year, lasting m beauty three weeks. The variety
