O. CIRRHOSUM HRUBYANUM, JJcM. /.-yThis handsome plant was first 

 exhibited by Messrs. Sander & Co., in FebBiiary, 1885, at South Kensington, 

 under the iiame of 0. Uruhyanum. It closely- rese,mbles 0. eirrlioswm both in 

 the shape and colour of its flowers, saving the'spotlling of the sepals and petals, 

 which are pure white with only a blotch of orsinge 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 o^ 0. cirrhosum. — New Grenada.

 flowers during the summer months. — Ecuador, 



O. CITROSMUM, Lindl. — A charming Orchid, producing long pendulous 

 spikes of fragrant lemon-scented flowers in May and June. 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 2 inches across ; the oblong obtuse nearly equal sepals and petals 

 are white slightly flushed and sometimes dotted with pink, the crestless 

 renif orm 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.
