Protection of Pollen. — The Royal 
Horticultural Society has taken stejis for the 
better protection of Orchids exhibited at their 
fortnightly meetings by reserving a portion 
of the staging for those plants which have 
received certificates. An attendant will be 
in charge, and a rope affixed some three feet 
away from the staging to prevent visitors from 
passing too near the plants. A printed notice 
with the following words will be attached : — 
" These flowers may on no account be touched 
by anyone during the continuance of the 
Show. By order of the Council." Exhibitors 
will therefore have a safe place wherein to 
deposit their valuables, but it remains to be 
seen to what extent it will be utilised. In the 
first place, it will be very difficult for anyone 
to obtain a clear view of these plants owing 
to the large number of admirers ; and, 
secondly, many exhibitors will prefer to leave 
them in their own groups situated in various 
parts of the Hall, for it is well known that 
certificated plants are the centre stars of 
attraction in most Orchid groups. However, 
the Society has done its best to prevent a 
repetition of the theft of pollen reported on 
page 148.

Sander's List of Orchid Hybrids. — This 
most useful book of reference to the many 
hybrids, both of past and present cultivation, 
fills a long felt want, for many amateurs have 
sought in vain for information which the book 
now imparts. Table i gives the names of the 
hybrids, arranged in alphabetical order, with 
the seed and pollen parents. The second 
table records, in the first column, those plants 
which have been used as seed parents, also 
arranged alphabetically, the name of the 
hybrid obtained being given in the third 
column. The third table is similar to the 
second, but gives the names of the pollen 
parents in the first column. Natural hybrids 
are included, but distinguished from those 
artificially raised by an asterisk prefixed 
against the name. The list of Odontoglossum 
and allied genera has been compiled by Mr. 
de Barri Cravvshay, and has thereby been 
brought up to date by the best existing 
authority. The book, which is substantially 
bound, consists of 140 pages, including the 
addenda, and has the advantage of numerous 
additional blank pages interleaved for the 
purpose of recording subsequent hybrids. 
The published price is 12s. 6d., and copies may 
be obtained from Messrs. Sander and Sons,

Cypripedium Roundhead. 
Cypripedium Roundhead. — The parent- 
age of this hybrid, illustrated above, is Earl of 
Tankerville (exul x nitens) x nitens (insigne 
X villosum), from which it will be seen that 
only three species are included. No one need 
suppose that it is necessary to combine a large 
number of species in order to obtain a superior 
hybrid, although such combinations may often 
result in the formation of a new cross. In 
Cypripedium Roundhead we see the result of 
selecting and hybridising only such flowers as 
show a tendency to increase the width and 
compact nature of their segments. When 
once a start has been made in this direction, 
every succeeding family includes individuals 
having a natural inclination to accentuate the 
improvement, and by this means the hybridi=;t
