ORCHID WORLD. 
MAY, 1913. 
NOTES 
RovAL Horticultural Society. — 
Fellows of the Society are reminded that in 
order to prevent the packing of plants on 
Whit-Monday, the usual fortnightly meeting 
has been altered to Wednesday, May 14th. 
The Great Spring Show will be held at 
Chelsea, May, 20th, 21st and 22nd, m 
the Royal Hospital Gardens, and on the 
site occupied by the igi2 International 
Exhibition.

Cattleya Schroder/E alba. — It has 
often been remarked that a pure white form of 
C. Schroderae does not exist, for although many 
plants produce flowers which open in a white 
state and give every appearance of an albino, 
yet before many days a blush or light purple 
tint is assumed. Messrs. Stuart Low and Co., 
Bush Hill Park, have recently flowered C. 
Schroderae " Puiity," which is a large flower, 
quite white, and after the period of 18 days 
remained in precisely the same condition. 
This seems to be conclusive proof of the true 
albinism of the variety. 
II H 
Cymbidium LowianuM. — A splendid 
specimen of this elegant Orchid is in Mr. Wm. 
Tod's collection, Dry Grange, Allerton. It 
has recently carried 18 magnificent spikes, 
each si.v feet m length, and when exhibited 
at the Liverpool Show, in April last, 
attracted considerable attention. The North 
of England Horticultural Society awarded the 
grower, Mr. Eaton, a Cultural Commenda- 
tion. This Society granted a Silver-gilt 
Medal to the same exhibitor for three 
specimens : the Cymbidium already referred 
to, Coelogyne cristata Lemoniana, and C. 
cristata Chatsworth variety.

Serrated Flowers. — Mr. W. Thompson, 
of Walton Grange, Staffs., has recently 
flowered a particularly beautiful and distinct 
Odontoglossum to which he has given the 
name Mrs. Thompson. The edges of the 
segments, especially the petals, are much 
serrated, or toothed, giving the flower a comb, 
or crest-like, appearance. The origin of this 
peculiarity may be traced to the influence of 
luteo-purpureum in the parentage, this species 
invariably having many prominent teeth on 
the edge of the petals. The parentage of Od. 
Mrs. Thompson is not known for certain, 
although it agrees very closely with Od. 
Lambardeanum, figured in the ORCHID 
World, Vol. II., p. 220, a hybrid which also 
contains luteo-purpureum in its pedigree. It 
is not unlikely that both originated from the 
same seed pod. Since several hybridists have 
expressed an opinion that before long it may 
be difficult to obtain new features in the 
flowers, this serrated nature may prove to be 
a point worthy of their consideration. Many 
varieties of Od. Wilckeanum are rendered 
attractive by their toothed petals, and such 
flowers make a contrast to the smooth edged 
blooms of the crispum t\-pe.
