ODONTOGLOSSUM. 429 



The sepals are narrow lanceolate, much attenuated at 

 the point and slightly undulated, the petals similar but 

 somewhat shorter and broader at the base, both white 

 thickly blotched with bright chocolate purple ; the lip is 

 smaller and shorter but equally attenuated, the expanded 

 base heart-shaped, yellow with deep crimson veins, and a 

 pair of prominent yellow horns white and spotted like the 

 petals on the anterior part. Some of the many forms produce 

 their flowers in panicles. The name cirrlioswn is given in 

 allusion to the slender recurved cirrhiform apices of the parts.

0. cirrhosum Hruhyanum, Bchb. f. — This handsome plant 

 was recently (February, 1885) exhibited by Messrs. Sander 

 & Co. at South Kensington. It closely resembles 0. 

 cirrJwsimi both in the shape and colour of its flowers, saving 

 the spotting of the sepals and petals, which are pure white 

 with only a blotch of orange and some red lines at the base 

 of the lip. The flowers are borne in long robust racemes 

 with about twenty blossoms. It is now considered to be a 

 variety of 0. cirrlwsum. — New Grenada. 



Syn. — 0. cirrhosum album; 0. Hrubyanum, 



0. cirrllOSlim Klabocliorimi, Bchh.f. — An altogether superior 

 form of the type, having much larger white flowers more 

 heavily spotted with chocolate-brown, and the sepals and 

 petals developed into much longer tails. It flowers during 

 the summer months. — Ecuador. 



0. citrosmuin, Lindley. — A charming Orchid, producing long 

 pendulous spikes of fragrant lemon-scented flowers in June 

 and July. It has roundish compressed pseudobulbs, oblong 

 ligulate leaves, and pendent racemes or panicles of large 

 handsome flowers, a dozen or more on one scape, each 

 flower measuring two inches across. The oblong obtuse 

 nearly equal sepals and petals are white slightly flushed and 

 sometimes dotted with pink, the crestless reniform emarginate 

 lip mauve-coloured with an orange yellow claw having the 

 two sides erect. It flowers in summer, and will continue 

 in perfection for as long as four weeks if kept in a cool house 

 free from damp ; moreover, it makes one of the finest plants 

 for exhibition. — Mexico.
