274 THE ORCHID REVIEW. [SEPTEMBER, 1909. 
brown at the margin, and the lip is porcelain white, with a slight suftusion 
of greyish green in front and olive green behind, while the column is light 
green, witha blackish purple blotch at the base. As regards shape little 
need be said, for the broad, fleshy sepals and petals, the ovate very fleshy 
lip, and the short column are all well shown in the figure, and contrast 
strongly with the narrow recurved membranous sepals and petals of the male 
inflorescence, with its small toothed lip and very slender column. The 
male inflorescence carried 21 flowers, but the lower nine had to be omitted 
from the photograph, in order to avoid excessive reduction. The sepals and 
petals of the male are light green, with a slight brown suffusion and many 
dark brown spots, and the lipis white. The female flowers were previously 
unknown, for the plant showing both sexes figured as C. maculatum earlier 
in the year (Gard. Chron. 1909, 1., pp. 26, 27, fig. 19) belongs to C. densiflorum, 
Rolfe, a species which was figured at page 104 of the present volume, 
and of which the denser inflorescence and much smaller male flowers will be 
immediately noticed. It is also figured at t. 8268 of the Botanical Magazine. 
The female flower mentioned on page 272 as possibly the unknown female 
of C. maculatum must also be different, and its identity remains uncertain. 
A complete collection of the species would form a very attractive feature in 
a Warm house, besides affording occasional surprises. Ki A. ROLFE, 
ORCHIDS AT WEST BANK HOUSE, HEATON MERSEY. 
THE collection of Orchids brought together by John Leemann, Esq., West 
Bank House, Heaton Mersey, is probably the finest in the North of England. 
Within the last three or four years the old Orchid houses have been taken 
down and rebuilt, with many additions, in a more suitable part of the 
grounds, and in the rebuilding Mr. Leemann has adopted every modern 
improvement for the welfare and comfort of his plants. Eight span-roof 
houses, each 50 ft. long, open intoa long heated corridor, 130 ft. long. The 
houses are double-roofed, the upper roof being raised about seven inches 
above the lower glass, and between these roofs the air plays quite freely in 
the summer time, and in the winter the intervening space can be wholly or 
partially closed, whilst a hot water pipe running between takes the cold edge 
off the ventilation before entering the houses. Mr. Leemann thinks very 
highly of this arrangement, particularly in the Cattleya and warmer houses, 
and the cultural results are everywhere excellent, and certainly justify this 
extra expense. = 
On entering the first house we find it devoted to all the best types of 
spotted and blotched Odontoglossum crispum and hybrids, for which the 
collection is famous, but brief mention can only be made of a very few. I 
noted strong plants of Odontoglossum crispum Perfection, O.c.rubellum,O- 
c. Autocrat, O. c. Brigadier, O. c. Campania, O. c. Luciani, &c. Of the white
