" Cypripedium rubescens Ranjitsinhji I 
purchased from the late Mr. Tracy a few days 
after I acquired Mrs. Wm. Mostyn. It was 
also exhibited in January, 1902, and received 
an Award of Merit. We raised five seedlings 
in 1903, which grew very slowly indeed ; four 
proved to be worthless, and were burned ; 
the other was Waterloo. 
" This Cypripedium requires to be grown 
rather cool to get its full colour, and when at 
its best I consider it to be by far the finest, 
in every respect, of the richly coloured ones 
When Mr. E. V. Low was here in November, 
1909, he acquired a piece of the plant, 
for whicih ihe received the doubtful honour 
of an Award of Merit last December. The 
rest of the plant, I am glad to say, remains 
here." 
Five species are responsible for Waterloo, 
in the following proportions : — Boxallii three- 
eighths, insigne a quarter, Spicerianum a 
quarter, villosum one-sixteenth, and barbatum 
one-sixteenth. The diagram will explaui 
more fully the precise method by which this 
remarkable combination of specific characters 
has been achieved.

ORCHIDS IN THEIR NATIVE LAND. 
The Vegetation of the Organ Mountains of 
Brazil. By George Gardner, F.L.S., 
Director of the Royal Botanic Garden, 
Ceylon. Being abstracts from his 
" Original Communications to the Hor- 
ticultural .Society," 1846. 
The Organ Mountains are situated to the 
north of Rio de Janeiro, and about 63 miles 
distant. They rise to the height of about 7,000 
feet, and take their name from the fancied 
resemblance which their peaks have to the 
tubes of an organ when seen from a distance. 
As the Bay of Rio runs from south to north 
about 20 miles, this part of the journey 
to the mountains is always made by water, 
and the sail is a very pleasant one, the bay 
being studded with many little verdant islands. 
The journey from the landing-place to the 
foot of the mountains leads through a flat, 
partly sandy and partly swampy country. The 
sandy parts are covered with low trees and 
shrubs. The marshy grounds are in general 
covered with forests of small trees, the most 
common of which is a simple-leaved, white- 
flowered Bignonia. On the stems of these 
trees grew three species of orchidaceous plants 
in great plenty. One of these is the lovely 
Cattleya Loddigesii, Lindl. ; the second, Onci- 
dium flexuosum, the stems of which are often 
SIX feet high and full of blossoms. The third 
is a species of Burlingtonia. The whole 
ascent of the mountains to the Fazenda, or 
farm, at which I resided during my stay in 
the mountains, belongs to Mr. March, an 
Englishman. His estate, which contains some 
64 square miles, and stands at an elevation of 
upwards of 3,000 feet, is covered with a dense 
wood. 
At this elevation the climate is very much 
cooler than it is at Rio. In the months of 
May and June the thermometer has been 
known tO' be as low as 32° just before day- 
break ; the lowest at which I observed it my- 
self was one morning at the end of May, when 
at eight o'clock a.m. it indicated 39°. The 
highest to which it rose during the six months 
I resided there was in the end of February, 
when one day it indicated 84° at noon. The
