THE ORCHID REVIEW. 105 
the happiest result, as they are now furnished with leaves down to the pots 
and apparently as healthy as if they had not been touched. A large plant 
of Stauropsis lissochiloides is throwing up a spike; Aérides expansum 
Leoniz shows 26 growths, and Vanda Denisoniana is represented by a 
good plant. In short, both genera are represented by many fine plants 
in robust health. This house also contains a large plant of Lelia 
superbiens, which is bearing a spike five feet long with nine large and 
handsome flowers. 
The Masdevallia house proper contains a large collection of plants in 
the most robust health, as is proved by their vigorous growth and deep 
green colour. The house is a lean-to, with the most ample provision for 
ventilation, which is utilised to the fullest extent whenever the weather 
permits. During the winter a temperature of 50° is maintained as nearly 
as possible, with a minimum of 45° in extreme weather; but Mr. Chapman 
considers that so low a temperature, except for a very short period, is very 
risky unless the plants are comparatively dry. Great care should be 
exercised in watering during the winter, but even then they should not 
be allowed to become dry. During warm weather the temperature is kept 
as low as possible by every available means. The result is excellent, as 
the plants are healthy and vigorous, and will doubtless flower freely when 
the proper season arrives. A plant of M. ignea was already pushing up 
well, and a large M. racemosa with 80 leaves is one of the healthiest we 
have ever seen. M. Harryana in its numerous varieties is represented in 
quantity, as also is M. ignea. M. Carderi has 70 leaves, M. gemmata 
roo, M. x Measuresiana 50, and M. irrorata 60. But it is unnecessary to 
prolong the list. The unique Pleurothallis punctulata, with its remarkable 
glaucous leaves, has 18 growths, while Restrepias and Scaphosepalums are 
represented in variety. 
The Odontoglossum house contains a thousand plants, and many good 
varieties. Among those in flower may be mentioned a very fine O. 
triumphans, and several forms of the O. x Andersonianum group. 
The last house is used as a resting house, and Mexican house in 
summer, and may thus be briefly be dismissed, as but little space remains 
for the hybrids, which form one of the most interesting features of the 
collection. 
__ Hybridising is carried on to such an extent that it is difficult to know 
where to begin. Perhaps some idea may be formed by the fact that already 
during the present year Mr. Chapman has sown. the contents of 36 
capsules, and has 60 more waiting their turn. Those which mature during 
the winter months are stored up in paper until the return of more genial 
weather, because the risk of loss is considered to be diminished by this 
means. P RODS aly: 
To enumerate the crosses already made would be a formidable task
