aware of any other. Consequently, hybridists are anxious to obtain seed- 
lings with as much of the character of this scarce variety as possible. They 
have made many attempts by recrossing the C. Fairrieanum hybrids in 
existence, but have always failed, although other hybrid Cypripediums will 
cross with C. Fairrieanum. For instance, C. X cenanthum superbum 
crossed with C. Fairrieanum produced a very scarce and beautiful variety, 
C. xX Baron Schroder. C. X vexillarium was obtained by crossing C. barbatum 
with C. Fairrieanum, and this hybrid on being crossed with C. bellatulum 
produced C. X bellatulo-vexillarium, but vexillarium was the pollen parent. 
The object of bringing this matter before the Scientific Committee at all 
would be to ascertain why, if other hybrid Cypripediums will cross with 
each other, how is it that C. xX vexillarium will not cross with C. x 
Niobe, or why C. X Juno will not cross with C. xX Arthurianum, or any 
other of the numerous ways in which the C. Fairrieanum hybrids may be 
crossed with each other? The pollen is potent enough if used on other 
species of Cypripedium. 
ORCHIDS OF CHINA. 
THE last part of the Journal of the Linnean Society is largely devoted to an 
enumeration of the Orchids of China, by Mr. Rolfe. The total number 
given is 270 species, belonging to 78 genera, and they are divided up: 
among the tribes as follows :—Epidendrez 99 species, Vandez 50 species, 
Neottiee 43 species, Ophrydeze 60 species, and Cypripediez 18 species. 
Twenty-three new species are added—one of which is the type of a new 
genus, Hancockia, allied to Nephelaphyllum—but some forty others had 
previously been published in the Annals of Botany. The largest genus is. 
Habenaria, with nineteen species, then follows Dendrobium with seven- 
teen, Calanthe and Cypripedium with sixteen each, Platanthera with 
twelve, Liparis with ten, Coelogyne, Cymbidium, and Sarcanthus with 
nine each, &c., while no fewer than thirty-eight genera are only represented 
by a single species. Among the more interesting novelties may be 
mentioned Dendrobium bellatulum, a very dwarf, large flowered species of 
the D. formosum group, now introduced to cultivation by Messrs. Veitch; 
and D. Hancockii, a beautiful yellow-flowered species, both from Yunnan. 
It will give some idea of the remarkable character of the Flora of the 
latter province, when it is mentioned that three North Indian yellow- 
flowered species have also been found there, namely, D. chrysanthum, 
D. clavatum, and D. Gibsoni; together with Cymbidium grandiflorum and 
Paphiopedilum Parishii. And it is particularly noteworthy that the 
Philippine Phalzenopsis Aphrodite also occurs in South Formosa, where it 
was collected by Dr. Henry.
