44 THE ORCHID REVIEW. | JANUARY, 1923. 
high percentage of germination is obtained, and it is said that when once 
the seed has been sown, or the seedlings transplanted, no further attention 
ds required until the time when pots are necessary. The seedlings are 
placed in pots when they have five or six leaves, and roots an inch or more 
in length. 
Under the conditions of growth existing in the tubes or flasks, the water 
is partially lost by evaporation, which results in a gradual hardening of the 
plants, so that they can be moved without danger. Mr. Knudson has 
shipped tube cultures to Florida, where the seedlings were transplanted, 
and where, four months later, out of 800so treated, very few died. The 
genera in which success has been obtained include Cattleya, Epidendrum, 
Dendrobium, Lelia, and Phalznopsis, the germination having averaged 
close to 100 per cent. As Odontoglossums and OQOdontiodas are not 
mentioned, it appears doubtful whether they can be raised by this method 
with equal success. 
L#LIOCATTLEYA ARIES VAR. Lapy THom.—Among the excellent results 
that have been produced from Leliocattleya Henry Greenwood (C. 
Hardyana X Lec. Schilleriana) are the superb Lc. J. F. Birkbeck, Lc. Sir 
Douglas Haig, Lc. Nairobe, and Lc. Aries (Lc. Henry Greenwood x C. 
Warscewiczii). At the recent Blackburn Show, J. McCartney, Esq., 
Hey House, Bolton, exhibited Le. Aries var. Lady Thom, a very fine 
variety named in compliment to the President. The segments of this flower 
are unusually stiff textured, and of a bright rosy-mauve colour, the labellum 
has the whole of its front lobe raby-crimson, while each of the side lobes 
bears a yellow disc that is characteristic of C. Warscewiczii. 
SOPHROLELIOCATTLEYA MARATHON.—In the production of this hybrid 
between C. Empress Frederick (aurea X Mossiz) and Sl. Psyche (L. 
cinnabarina X S. grandiflora), it will be seen that the latter parent is 
composed of two red flowering species, and these have contributed the 
beautiful reddish tints that give so much satisfaction to owners of choice 
varieties of Slc. Marathon. The fine results achieved by the above 
combination led to Sle. Marathon itself being used as a parent, and with 
such success that, in the words of a hybridist, it seems impossible to make 
a bad cross with it. We -may recall the magnificent Potinara Juliette, 
obtained by crossing Marathon with Brassocattleya. Ena,-as well as Slc. 
Vesuvius, Sle. Joyce Hanmer, and many others. In Slc. Warnathon, 
obtained by crossing C. Warneri with Slc. Marathon, there exists a 
“particularly pleasing hybrid with soft reddish tints on a terra-cotta ground 
colour. It has recently flowered for the second time in the collection of P. 
Smith, Esq., Haddon House, Ashton-on-Mersey (gr. Mr. S. W. Thompson).
