108 THE ORCHID REVIEW. [APRIL, 1922- 
Certificate and Silver Medal were granted to the plant exhibited by Dr. F. 
Bedford, who purchased it in a very weak state at the sale of the late 
Mr. F. M. Ogilvie’s collection at Oxford. 
SELF-FERTILISATION OF CYPRIPEDIUM SCHLIMII. 
OR some time after its first introduction in 1854, Cypripedium Schlimit 
7 was a very rare plant in British Gardens, and horticulturists took 
advantage of its self-fertilising power to raise young plants from seed. 
Regarding this peculiarity, Messrs. Veitch have stated (Wanual of Orchid- 
aceous Plants, iv., p. 68): ‘‘ The sexual apparatus of this species differs in 
no essential character from others of the genus, but, as is the case with all 
Selenipedia, the relative position of the stigmatic disc to the other parts is 
somewhat modified; this disc is rhomboidal in outline, much thickened 
beneath, especially on the basal side, forming there a conical protuberance 
that stands immediatly below the anthers, is nearly parallel with the 
staminode, and projects beyond it. The anthers are normal as regards form 
and position, but the glutinous envelope is exceedingly thin, loses its 
viscidity after the flower has been some time expanded, and becomes dry; 
the granular pollen is then set free upon any slight motion imparted to the 
flower ; and as these granules are exceedingly minute and numerous, it can 
scarcely happen that some of them do not fall upon the stigmatic disc, 
especially the thickened part that projects immediately below the anthers, 
and the ovary thence becomes fertilised. The consequence to the plant is 
the enfeebling of its constitution, by which the species is one of the most 
difficult to import alive, and scarcely less difficult to keep alive when so 
imported.” 
Tuuntias.—Plants belonging to this genus should be grown in the East 
Indian house, and be treated liberally with water. The drainage should be 
perfect, and the potting material should be rough peat and sphagnum in 
about equal parts. After the flowers have passed and the leaves have fallen, 
water should be entirely withheld, and the plants removed to a lower 
temperature. When growing they enjoy an abundance of sunshine. AS 
as they show signs of growth, about the beginning of March, they should 
© potted, and when the young roots appear water should be given them 
sparingly. Thuntas may be propagated by division, and also by cutting up 
ghosts aa oes Six inches long, and inserting them ina ee 
elected Hal Ghat He inary cuttings. This latter operation should be 
young growths are complete.—B. S. WILLIAMS.
