A CYPRIPEDIUM HOUSE, 
(Concluded from page 1098.) 
I HAVE now about 130 plants; 70 are Cypripedes, of which I have 30 
species, I natural and 2 artificial hybrids, and 1 Phragmopedilum x Sedenii. 
The house is run to suit the warm growing Cypripedes and the cooler 
Cypripedes do not appear to suffer much. I forgot to mention that the felt 
covers are of the greatest service in maintaining a moist atmosphere in the 
house at night without frequent damping of the floor. I also omitted to 
say that the day temperatures given apply to the warmest part of the house 
on a sunny day. 
THE C. BELLATULUM SECTION.—The plants I have, when bought in 
1906, consisted of nine very small pieces and single growths. At that time, 
though most of the leaves were healthy, none exceeded 3}in. by trin., and 
the average was smaller. The plants were starved. These plants now fill 
one six and four five inch pots to overflowing, and have leaves up to gin. by 
2tin., the average full-grown leaf being about 7in. by r#in. In my 
experience bellatulum is one of the most rapid and free growing of all 
Cypripedes. They are potted much after the methods advocated by the 
late Mr. R. Young, O. R., iv. 45, the late General Berkeley, O. R., v. 236, and 
Mr. O. O. Wrigley, O. R., vii. 146. Others have mentioned the same or 
somewhat similar methods, but I believe that the gentlemen named were 
the pioneers of what may truly be called the commonsense plan of potting 
this section. 
In potting C. bellatulum I like a rather deep pot, for pots under 6in. I 
generally use ‘‘long thumbs.” In a 6in. pot I place lumps of old mortar, 
the larger the better, to a depth of about I4in. (this may be increased), 
securing the drainage with a thin layer of fibrous loam. I then build up in 
the centre a pile of lumps of mortar and a little loam, finishing the pile with 
a large lump of mortar for the base of the plant to rest on. The roots are 
allowed to hang down round the central pile, and the pot is filled with 
alternate layers of lumps of mortar, of in. to 14in. diameter, and loam, the 
latter being mixed with 2 to 3 oz. of mortar crushed to sand size. I prefer 
a sandy clay loam, but I have used good fibrous loam or a mixture of these
