JUNE, 1923-] THE ORCHID REVIEW. 187 
“very hairy,” refers to the shaggy nature of the infloresence. Formerly 
this Cypripedium was well represented in collections, but of late years its 
place has been taken by plants of hybrid origin which, although producing 
somewhat larger flowers, lack the historic interest that is always associated’ 
with long established species. It is, however, pleasing to note that a 
typical example has recently been flowering well in the garden of Mrs. E. 
W. Jessie Johnson, Nevill Park, Tunbridge Wells. 
CocHtiopa Na:zLiaANA X ODONrOGLOssUM CITROSMUM.—The late M.~ 
Jules Hye de Crom, of Ghent, was a keen raiser of Orchid hybrids, and 
among the experiments he made was the crossing of Cochlioda Noezliana 
with Odontoglossum citrosmum. Although about 300 little seedlings were 
obtained by his grower, M. Coene, their cultivation was always a matter of 
great difficulty, and one by one they perished, the last living for a period of 
nine years, but never strong enough to produce a flower spike.

Oncip1um MARSHALLIANUM.—Anyone who can master the cultivation 
of this beautiful species will earn the thanks of all amateurs, for despite 
various methods no successful treatment has as yet been devised that wilk 
keep the plants in vigorous condition for several successive years. Imported 
plants flower well the first season or two, but gradually decline in health. 
Cool-house treatment appears to yield results better than when warmer 
treatment is given. Could not one of our successful seed-raisers produce a 
batch of plants from seed ripened and germinated in this country ? Perhaps. 
then the plants will respond to our climate with greater vitality. 
ODONTOGLOSSUMS FROM THE ROSEFIELD CoLLecrion.—Although the 
well-known ‘collection of de Barri Crawshay, Esq., Rosefield, Sevenoaks, 
was disposed of by auction in IgI9, a few special plants were reserved by 
him and sent on to Messrs. Armstrong & Brown for preservation. We 
have recently received flowers from some of them. The first is historic, for 
it represents the first artificially raised O. crispum in England, the 
earliest flower being seen on August 13th, 1900. Another is O. Dircimium,. 
the result of crossing Dirce rosefieldiense with eximium Warnham = 
var.; it has reddish-purple blotching surrounded by a pleasing violet tinge, 
and a narrow white border to the segments. The first seedling of this. 
parentage flowered in the collection of C. J. Lucas, Esq., W arnham Court, 
Sussex, in rgt8. Another of Mr. Crawshay’s hybrids is Odontioda Mars 
(Odm. Lawrenceanum X Oda. Charlesworthii), of thick texture, and a deep 
red colour on all the segments, except the lip, where it is broken up into a 
large blotch across the middle, and freckling at the apex.
