34 THE ORCHID REVIEW. [FEBRUAR\, 1908. 
Only two kinds of pollen were used, and two hybrids was the result. 
What would have happened if half-a-dozen kinds had been used is more 
than I can guess, but I fully expect that the experiment will now be made. 
I have never heard it stated how many pollen tubes one single pollen-mass 
of Cattleya will produce, but it must be enormous, for the number of seeds 
in a capsule is so great that if all were to germinate the grower would not 
know what to do with half of them. In practice, I believe, this is seldom 
the case, but too many seedlings from a capsule is not an unheard-of 
experience, and is highly inconvenient when space is limited. But if the 
hybridist could arrange to put a few grains from several different Cattleyas 
and Leelias on the stigma of some good seed parent he might get some sur- 
prising results. The suggestion may be taken for what it is worth, and 
there I will leave it. 
The note about the distribution of Brazilian Cattleyas, given at page 21, 
is very interesting, and especially the information about C. velutina. Only 
a few months ago two natural hybrids from it were described, and now we 
hear of two others. It certainly does appear that our knowledge of the 
distribution of these plants is very limited, but I hope that our friend will 
hasten to enlighten us. 
The same note indicates another possible development, for if seeds of 
Cattleyas and Leelias can be sent from Brazil, 
here, there seems no particular reason why t 
certain other kinds which are difficult to import alive. I commend the 
information to some of our importers of Orchids. ARGUS.

ODONTOGLOossuUMs.—At the meeting of the Bolton Horticultural Society 
held on Tuesday evening, January 7th, the subject was the Cultivation of 
Odontoglossums, by Mr. Wm. Holmes, Orchid grower to Mr. J. McCartney, 
Hey House, Tonge Moor, Bolton. Odontoglossums are found growing on 
rocks, or on the bark of trees, on branches and trunks in Tropical America. 
The most popular varieties are found on the mountain chain of South 
America, some at an altitude of 5,000ft., some at 7,000ft. to g,oooft., and a 
few were found up to II,000ft., where the rainy season was almost 
continuous throughout causing a dense vapour similar to fog. 
€ most light and air found its way, others 
ised growers to take all these matters into 
ing in greenhouses. A hearty vote of thanks 
had a collection of Odontoglossums in 
es, for which he was awarded a Certificate 
orticulture, 
of Merit.—G. C. in Journal of H
