NOMENCLATURE OF MULTIGENERIC HYBRIDS. 
HEN the first generic hybrids made their appearance it was a com- 
paratively easy matter to form suitable names. Leliocattleya, 
Brassocattleya and Sophrocattleya are well-known examples in which the 
parental names have been combined for the purpose of classification. But 
with the combining of three genera longer names came into use, and with 
such cumbersome terms as Brassolzliocattleya it became evident that a new 
scheme of nomenclature would be necessary to prevent further examples. 
_At the International Congress held at Brussels in 1910, it was decided that, 
in future, multigeneric hybrids should receive a conventional generic name, 
preferably that of a distinguished man, with the termination “ ata.” 
VUYLSTEKEARA. The first example to come under the new scheme was 
the hybrid between Cochlioda Noezliana and Odontonia Lairressee 
exhibited by M. Jules Hye at the Royal International Horticultural 
Exhibition of 1912. It contained the three genera Cochlioda, Odonto- 
glossum and Miltonia, and was recorded as Vuylstekeara Hyeana. Fifteen 
additional hybrids containing the same three genera have since been 
registered, and judging by recent results, this number will soon be con- 
siderably increased. 
Lowrara. The combination of the three genera Sophronitis, Lelia and 
Brassavola was first flowered by Messrs. Stuart Low & Co., who exhibited 
the plant at the Royal Horticultural Society, November rgth, 1912, under 
the name Lowiara insignis. It was obtained by crossing Sophronitis 
grandiflora with Brassolelia Helen. Lowiara Paul (BI. Mrs. M. Gratrix x 
Sl. Psyche), raised in the collection of Col. Stephenson R. Clarke, C.B., 1s 
_the only other example yet flowered. 
Witsonara. The combination of Cochlioda, Odontoglossum and 
Oncidium was flowered by Messrs. Charlesworth & Co. in 1916, and 
-Fecorded as Wilsonara insignis (Odontoglossum illustrissimum X Oncidioda 
Charlesworthii). A second example exists in Wilsonara Sandere, the 
result of crossing Odontioda Sandere with Oncidium macranthum, and a 
third in W. majalis (Odontioda Chantecler X Oncidium corynephorum). 
RoLFEARA. The mating of Sophrocattleya Blackii with Brassocattleya 
Mrs. J. Leemann brought about the fusion of the three genera Cattleya, 
Brassavola and Sophronitis. This hybrid was raised in the collection of 
Mr. Richd. G. Thwaites and first flowered during the autumn of 1918, 
being recorded in the early part of the following year as Rolfeara rubescens. 
Two other hybrids in this section have since been raised. 
Cusuiecwouraiana.. Abitbe mecting.of the: Boy al Horticultural 
Society held June 17th, 1919, Messrs. Charlesworth & see exhibited
