146 GENERAL REVIEW OK THE ORCHIDE^. 



splendidissimmn from the same parentage as I), x Ainsworthii, of 

 which therefore it is strictly but a fine variety, and this was after- 

 wards followed by its variety grandijiorum, the facile princeps of 

 the group of hybrids obtained from D. noblle and D. aureiim. Later 

 additions were made in B. x euosmum, a secondary hybrid, and 

 which like most secondary hybrids proved a variable progeny, B. x 

 Schneider ianu77i , previously raised from the same parentage by Holmes, 

 D. X Virginia, D. x Enri/alus, D. x Cordelia, and D. x Aspasia 

 subsequently obtained by Mr. Wmn, of Birmingham, from the same 

 pair of species {D. Wardianum x D. aureura). 



Among the finest Calanthes raised by Seden are G. x Sedenii, a 

 secondary hybrid with C. x Veitchii for one parent ; the very distinct 

 G. X lentiginosa also a secondary hybrid raised from G. x Veitchii 

 and 0. lahrosa, the sub-variety carminata of this hybrid is one of the 

 darkest-coloured Calanthes of the Vestitj: section yet obtained ; and 

 G. X Glgas, one of the most robust forms in the section. Quite distinct 

 from all these and bearing a strong analogy to Dominy's bigeneric 

 hybrid Fhalocalanthe Irrorata but far superior to it is Phaiocalanthe 

 Sedeniana, but still unfortunately very rare, so few plants being 

 obtainable from generic crosses ; and lastly Phaiocalanthe insperata 

 from Phaius grandifolius and Calanthe masuca, and thence the first 

 Phaiocalanthe in which a species of the VeratrifolO'; has partici- 

 pated in the parentage, the more remarkable since all attempts to 

 cross species of the Vestit.e section of Calanthe with species of the 

 Veratrtfolc.e have hitherto failed. 



Of the genera in which Seden was the first operator to obtain 

 artificially raised hybrids, Chysis was the earliest. In this restricted 

 genus two were raised, Ghysls x Ghelsoni and C. x Sedenii. Nearly 

 contemporary with the first flowering of Ghysis x Ghehonii was that 

 of Zygopetalum x Sedenii, followed some years later by the generic 

 hybrids Zygocolax leopardinus and Z. Veitchii. In Epidendrum, E. x 

 Ohrienianum was the first hybrid raised, and more recently the 

 beautiful E. x Endresio-WalUsii. The first hybrid Masdevallia raised 

 artificially was M. x Ghehonii which flowered in 1880, followed later 

 by M. x Gairiana, M. x glaphyrantha, M. x Ellislaiui, and M. x 

 candata-Estradce, all beautiful additions to the genus, and also the 

 progeny from i¥. Veitchlnna x M. Barlceana ah'eady mentioned.*
