292 THE ORCHID REVIEW. [Ocroper, roy. 
other houses in this range full of Lelio-cattleyas, while one has quantities _ 
of Phalzenopsis amabilis Rimestadiana and P. Lueddemanniana, and alsoa y 
fine lot of Pachystoma Thompsonianum. Here were also a thriving lot of 
Thunia hybrids, and a further lot of about three thousand Cypripedium e 
seedlings. The last house visited is called “the hospital,’ for here the 
cripples of the collection are nursed back to convalescence—or else dis- 
appear. . ; 
One misses the big lots of imported plants that used to mostly fill this 
establishment, but importations now mostly find their way to the establish- 
ment of Messrs. Sander at Bruges. At Bruges also are grown most of the 
Odontoglossums, where I am told they are now being raised from seed 
with entire success. 
Messrs. Sander are also interested in new plants, and at their St. Albans. 
establishment a considerable amount of glass is devoted to their cultivation, 
but they do not come within the sphere of this work. 
CYPRIPEDIUM CULTURE. 
Mr. Gott was kind enough to give me, during my recent visit there, a 
brief outline of what he considers to be the requirements of Cypripediums. 
Mr. Gott has raised and grows a good many thousands—and he grows and 
propagates them well, so that his ideas deserve every consideration. 
To grow a collection of Cypripediums successfully Mr. Gott says that it — 
is necessary to have two houses, one house for the green-leaved species, 
such as insigne, villosum, Boxallii, Spicerianum, &c., and the hybrids 
derived from these, such as nitens, Sallieri, Leeanum, Lathamianum, 
Calypso, &c., and one for the variegated or mottled-leaved kinds. : 
His experience has taught him that the former revel in abundance of 2 
night moisture, and he has never known an instance where they have damped : 
off through having too much moisture on the leaves. In districts where : 
there are night mists (not smoky), and where this moisture is thus afforded : 
naturally, these kinds always do well. An all-the-year-round temperatute — 
of 50°—55° by night and 60°—65° by day should be aimed at. : 
The variegated or mottled-leaved kinds require about ten degrees more 
heat than the green ones, and with them should be grown some greey — 
leaved exceptions, such as Stonei, Rothschildianum, Sanderianum, and alst : 
the Selenipediums. These mottled-leaved kinds require far less moisture it 
the atmosphere, much more light, and a less rich and close potting mixtures 
i.c. less loam than the former. RP 
Mr. Gott particularly deprecates the Turkish bath atmosphere which 
one too often finds in Cypripedium houses in summer, as it is both bad for 
raising seed and growing plants, and simply exhausting them by forcines 
and he would point out that they grow very little during very hot weather.
