of white, the disk marked by a few crimson-purple veins, which are flat and not 

 raised like a crest as in the allied L. /awa. It flowers during May and June, 

 and lasts for three weeks in beauty. There are two varieties of this species, 

 one with much larger flowers than the other. — Brazil.

 the lip. It was flowered by B. Wischussen, Esq., of Wood Green. 



LAELIO-CATTLEYA, Rolfe. 



(Tribe Epidendreae, snbtrlbc Laelieae.) 



A genus of hybrids, which have for the most part been obtained 

 artificially between species of the two genera here named, others are 

 supposed natural hybrids, and which, like those obtained under cultiva- 

 tion, appear to be defective in some portion of their generative organs. 

 They resemble in general appearance one or other of their two parents, 

 producing large and showy flowers. This hybrid, genus was established 

 by Mr. Rolfe, in the Journal of the Linnean Society, 1888, xxiv. p. 168. 

 The same author, when writing of Laelio-Cattleya elegans and Laelio- 

 Gattleya Schilleriana in the Orchid Review makes the following remarks, 

 which we here reproduce by kind permission : — 



"These two handsome Orchids are now flowering in various collections, 

 and the receipt of several inquiries respecting them, in four instances 

 accompanied by flowers, suggests the desirability of placing on record 

 the following notes, as some of their varieties have been, and still are, 

 considerably confused. Both are natives of the Santa Catherina district 

 of South Brazil, and from a variety of considerations it is certain that 

 both are of hybrid origin. In the district in question, three well-known 

 species occur, and in certain localities at least they grow intermixed, or 

 in close proximity to each other. These are Laelia purpvrata, Cattleya 

 Leopoldi, and G. intermedia. The former of these has stout pseudobulbs, 

 each with a single erect longish' leaf, and the flower has an entire lip, 

 and eight pollinia ; the two latter have slender stem-like pseudobulbs, 

 each with a pair of rather short spreading leaves, and the flowers have a 

 three-lobed lip, and four pollinia. The two latter, as is weiU known, are 

 markedly different from each other in colour of their flowers, and in 

 various details of structure. It is very interesting to observe the way
