228 THE ORCHID REVIEW. [AUGUST 1922. 
called leucochilum. It received a First-class Certificate when exhibited by 
Messrs. Sanders, R.H.S., July 1906. Some varieties have the lip spotted 
similarly to the other segments. These plants are still much sought after 
by amateurs, and in a fine importation of C. Godefroyz recently received 
by Messrs. Sanders, both sections are included, as is proved by some white, 
and also spotted, lipped varieties flowering prematurely long before the 
plants have had time to establish themselves. The wide variation seen 
gives much hope for the discovery amongst them of not a few really fine 
and distinct varieties. One may recall the variety citrinum, which received 
an Award of Merit, R.H.S., in 1905, also the Hessle variety, F.C.C., 
R.H.S., 1902, and the fact that no less than ten awards have been given on 
different occasions to this Cypripedium by the Royal Horticultural Society 
proves that varieties of merit undoubtedly occur. 
Cypripedium Godefroy, C. bellatulum, C. concolor and C. niveum 
are closely allied, and in a very interesting article by Dr. Miles Johnston 
which appeared in the Orchid Review, August, 1910, details of their 
successful cultivation are given. For the benefit of new subscribers we 
repeat the following: ‘‘In potting C. bellatulum I like a rather deep pot, 
for pots under 6in. I generally use ‘long thumbs.’ In a six inch pot I place 
lumps of old mortar, the larger the better, to a depth of about 1} in. (this 
may be increased), securing the drainage with a thin layer of fibrous loam. 
I then build up in the centre a pile of lumps of mortar, of }in, to I#in. 
diameter, and loam, the latter being mixed with 2 to 30z. of mortar crushed 
to sand size. I prefer a sandy clay loam, but I have used good fibrous 
loam or a mixture of these with good results. I pot rather firmly, but 
do not allow the loam to be squeezed into dense lumps. The mortar is 
soaked for a day or two in water before use. I make the surface of the 
compost about fin. below the rim and allow it to rise a little in the centre. 
The plants should be so arranged that the point from which new roots may 
be expected to spring is at, or very little below, the surface. The compost 
{excluding drainage) should consist of about one half lumps of mortar and 
one half loam. Moss, whether in or on the surface of the compost, is bad 
for the plants. Chalk may be substituted for the mortar, but I ‘believe the 
Jatter is better. C. concolor, C. Godefroye and C. niveum grow very well 
with a slight modification of the above method. For these I use smaller 
_ and deeper pots in proportion to the size of the plants than for bellatulum. 
More than three-quarters of the potting material consists of lumps ° 
mortar. The remaining quarter, used only for filling in the spaces between 
the lumps of mortar and for lightly surfacing, is a mixture of loam two 
on on chopped oak leaves one part, and crushed mortar one part.” An 
interesting article on the bellatulum-niveum group, by Mr. Harold Raven, 
appeared in our March issue of the current year.
