2 | THE ORCHID’ REVIEW. (JANUARY 1922. 
flowered, and, instead of being rich rose-purple, is, strange to relate, pure 
white, excepting a faint mauve tint on the front lobe of the labellam. Mr. 
Thwaites writes that as there is always a possibility of an error creeping in, 
the records have been examined most carefully, and there is nothing that 
could produce such a seedling as this except the above-mentioned parent. 
Although the flower reminds one of C. labiata Amesiana, there is no doubt 
whatever that it is a seedling from C. labiata Blenheim variety self- 
fertilised, so we have named it C. labiata Blenheim alba. <A second 
seedling has since flowered, and is coloured like its parent, so both purple 
and white varieties are being produced from the same seed-pod. 
VANDANTHE TATZERI.-~This interesting hybrid between Vanda tricolor 
and Euanthe Sanderiana (Vanda Sanderiana) was raised by Mr. A. Tatzer 
in the Botanic Garden of Prague University. The cross was made in 1909, 
and the plant produced its first spike of seven flowers in August, tgtg. It 
is described in the Ovchis, Oct., 1919, the flowers being intermediate in 
character, as is the case with most primary hybrids. On account of 
structural differences in the flower, Dr. Schlechter in IgI4 separated 
Vanda Sanderiana and made it the type plant of the new genus Euanthe. 
This explains the termination of the generic name of the present hybrid, 
which, having regard to the creation of the above new genus, must be 
considered of bi-generic character. : 
Rapip CULTIVATION oF CaTTLEYAS.—Recent results in the cultivation 
of Cattleyas show that these plants can be grown very quickly, provided 
they obtain the essential atmospheric conditions. Warmth and humidity 
always encourage the production of growth, but to obtain flowers of high 
quality, bright light in the way of diffused sunshine, is an equal necessity- 
Although the season of 1921 will long be remembered for its continuity of 
fine weather, much of the benefits derived therefrom were brought about by 
the skilful way in which these factors were utilised by the cultivator. In 
the rapid cultivation of Cattleyas, : 
Messrs. Hassall & Co., and among t 
alba, is worthy of being placed on r 
during the autumn of 1920, and completed the bulb in the early part: of 
, sheaths were duly formed, but they did

These plants were one of the features of Messrs. 
Hassall’s group at the R.H.S. Autumn Show, held on. November tst, Ig2t..
