Moscow Orchid Society. — We hear 

 from Dr. J. Troyanowsky that the Moscow 

 Orchid Society, of which lie is the worthy 

 president, continues to hold its meetings and 

 to sustain a keen interest among its members, 

 who are ever ready to exhibit their special 

 plants and discuss Orchid matters.

Cypripedium cenanthum Ginoti. — This 

 beautiful albino hybrid, the result of crossing 

 Harrisianum albens and insigne Sanderianum, 

 has been raised by M. Jos. Ginot, St. Etienne, 

 France, who kindly sends a flower for our 

 inspection. In colour it is yellowish-green, 

 the petals obscurely lined with light green, 

 while the dorsal sepal has the basal half 

 distinctly veined with emerald-green, and the 

 upper portion pure white. The tufts of hairs 

 on the base of the petals and those around 

 the column are entirely devoid of colour. 

 Even insigne Sanderianum has had its effect, 

 for there are no small spots of colour on the 

 central part of the flower, as is usual when 

 insigne Sanderje is used. Harrisianum is a 

 cross between barbatum and villosum, but 

 there appears some uncertainty as to the 

 origin of the albino variety. Some twenty 

 years ago a light greenish variety, which 

 appeared in more than one collection, was 

 recorded as Harrisianum virescens, and in later 

 years the variety albens was often met with ; 

 in both cases all trace of the purple-brown 

 colour had disappeared. In 1899, Mr. R. H. 

 Measures, of Streatham, published a list of all 

 his Cypripediums, in which mention is made 

 of 41 varieties of Harrisianum, these including 

 both albens and virescens, as well as The 

 Albino, the latter stated to have been named 

 by the late .Sir Trevor Lawrence. M. Ginot 

 states that he fertilised the Harrisianum 

 albens on November 7th, 1908, and in 

 addition to insigne Sanderianum used the 



pollen of insigne Godseffianum (an albino 

 form). The first seedling flowered in 

 December, 1913. Those produced by the 

 use of the variety Godseffianum are entirely 

 different, having longer stalks and being of a 

 more yellowish-green. M. Ginot also informs 

 us that last year he flowered Cyp. Krishna var. 

 Ginoti, an albino variety raised by him 

 through the use of a distinct form of tonsum 

 and insigne Sanderianum.

No Staging. — As several paragraphs on 

 the subject of staging have appeared in 

 recent issues it may not be inappropriate to 

 insert an additional one under the title No 

 Staging. When the writer, some years ago, 

 visited the immense nursery of Messrs. T. 

 Rochford, of Broxbourne, he was in no small 

 measure surprised to find a large span-roof 

 house filled with a multitude of Cattleyas, 

 everyone suspended from the roof, which, 

 needless to say, was strongly constructed. 

 This method allowed each plant to receive its 

 full share of light, and to be thoroughly well 

 ripened at the conclusion of the growing 

 season. The cultivator walked beneath his 

 plants, and not in between them as is 

 generally the case, consequently the whole of 

 the roof area was available ; there was no loss 

 of space occasioned by pathways. Ingenious 

 as this principle appears, it had certain 

 drawbacks of a detrimental character, for 

 there was the heavy work entailed in watering, 

 as well as the difficulty experienced in 

 periodically examining the new growths. 

 This house reminded one of a huge vinery, 

 though choice flowers took the place of luscious 

 grapes. I understand that Messrs. Stuart 

 Low and Co., of Jarvisbrook, achieve much 

 success with their Dendrobiums, which are 

 suspended from the roof in a house where no 

 staging is used. This seems to me quite a 

 reasonable method, for when long bulbed 

 plants are cultivated in the small pans so 

 necessary to ensure healthy growths it is 

 almost impossible to arrange them with any 

 degree of security on the ordinary staging ; 

 more especially will this be experienced when 

 the plants are in flower and considerably
