colour, while the petals, lip and column are white. The history and 
affinities of the genus have already been given, and we may remark, in 
conclusion, that the one-sided. racemes, the inverted flowers, the very 
concave side lobes of the lip, forming a rounded sac at the base, and a 
curious fringed margin which surrounds the base of the column in front are 
all remarkable. Their precise significance in the economy of fertilisation 
can only be inferred at present.

ORCHIDS AT COOKSBRIDGE. 
ABOUT three years ago we had the pleasure of seeing the establishment of 
Messrs. J. & A. A. McBean, at Cooksbridge, and of noting some of its 
prominent features (O.R., xv. pp. 228-231), particularly with respect to the 
raising of seedling Odontoglossums, which was being taken up in earnest, 
after some of the initial difficulties had been overcome. An opportunity 
recently presented itself of calling there again, and we were not surprised 
to find that during the interval great progress: had been made, not only with 
Odontoglossums but with various other genera. This establishment now 
contains an enormous number of seedlings in various stages, and we noted 
a number of interesting crosses that have been made, also a number of 
Orchids that were also seen in bloom in passing through the various houses, 
and we may now give a few details. 
Two erratic crosses confronted us at the very outset, for on entering the 
first house, containing numerous Lezliocattleyas, Cymbidiums, and other 
seedlings in various stages, we were Shown young plants derived from 
Zygopetalum xX Cymbidium, and others from Epidendrum radicans X 
Bletia Shepherdii, both resembling the seed parent in habit. The former 
will not improbably result ina batch of pure Zygopetalums—at all events 
if history repeats itself—but the behaviour of the latter will be watched with 
interest, for Epidendrum radicans has a reputation of another kind. The 
next house was also devoted to seedlings of various genera, and here some 
plants were pointed out as the result of crossing Brassavola nodosa with 
‘Cattleya Mendelii. 
On entering an Odontoglossum house we noticed in bloom plants of O. 
Harryanum, O. Wallisii, O. Uroskinneri, and Cochlioda Neetzliana, and a 
lot of capsules on the latter told of hybridising operations. Some nice 
plants obtained by crossing this species with Oncidium macranthum were 
pointed out, and we,could not help wondering what the flowers would 
be like. Seedlings from C. Neetzliana x Odontoglossum nebulosum were 
also interesting, but repeated attempts to raise the reverse cross have only 
ended in failure. There were also seedlings from O. Edwardii crossed with 
Ada aurantiaca and with Oncidium hastilabium. Seedling Odontoglossums
