factor must be in the material from which we 
are to construct our anticipated yellow 
flowering Orchid. 
On previous occasions we have remarked 
on Laslia Cowanii, L. harpophylla, and L. 
xanthina as being suitable species for produc- 
ing a yellow flower. Laslia cinnabarma,, 
however, although containing red and yellow, 
has invariably been used with the idea of 
bestowing a reddish tint, and, it must be said, 
with no small amount of success, but in this 
instance its powerful influence has resulted in 
the yellow colouring matter being spread over 
the whole of the large flower derived from the 
combination of Mossiae and Schroderas. The 
rich red of the cinnabarina parent has almost 
disappeared, leaving only the yellowish por- 
tion to be carried forward, most probably by 
the influence of the Schroderas, for this latter 
species has a wonderful effect in varying the 
colour in hybrids of which it is a parent. It 
is a well-known fact that great diversity 
appears m the numerous hybrids known as 
Laslio-Cattleya G. S. Ball (cinnabarina x 
Schroderas), and also in L.-C. Fascinator 
(purpurata x Schroderae). One does not like 
to suggest how this variation in colour takes 
place, or in how many of the seeds from this 
pod is it likely to occur. 
The variety of Helms represented in our 
coloured plate may be the only example of 
its kind possessing such remarkable colour, or 
others may eventually flower of .somewhat 
similar design. A large number of seedlings 
have been raised, all showing more or less the 
distinct cinnabarina habit of growth, and of 
those which have flowered, now a considerable 
number, no other in any way approaching our 
illustration has appeared. Laelio-Cattleya 
Helius has been raised by Messrs. J. and A. 
McBean in their extensive establishment at 
Cooksbridge, where the numerous plants of 
this hybrid are being grown. The superb and 
remarkable variety, so well reproduced in our 
coloured plate, has passed into the valuable 
and renowned collection of Baron Bruno 
Schroder, where its sun-like nature imparts 
increasing radiance to the many other 
heavenly flowers that never fail to welcome 
the sunshine of the sky.

Messrs. Charlesworth and Co., Haywards 
Heath, were awarded a Silver Flora Medal 
for an attractive group of excellent hybrids. 
Of special merit were Oncidioda Cooksoniae 
and Oncidium splendidum aureum, the latter 
a very rare albino form. Helcia sanguino- 
lenta and the rare Zygopetalum Mackayi 
Charlesworthii were also shown. 
Messrs. Sander and Sons, St. Albans, 
secured a Silver Banksian Medal for a very 
interesting exhibit of rare botanical Orchids, 
including Laelia Lundii, with its miniature 
flowers having the lip veined with purple- 
blue ; Pleurothallis cardiothallis, with a 
singular red-brown flower in the centre 
of a large leaf ; and various species and 
hybrids. 
Messrs. J. Cypher and Sons, Cheltenham, 
were awarded a Silver Banksian Medal for a 
smart group of Calanthe h}'brids, Phalaenopsis, 
and many excellent Cypripediums. 
Messrs. Jas. Veitch and Sons, Chelsea, 
obtained a Silver Banksian Medal for a good 
group of Cypripediums, Cattleyas, including 
the elegant Trianas Courtauldiana, Odonto- 
glossum hybrids, and several useful Oncidiums. 
Messrs. Stuart Low and Co., Bush Hill 
Park, Enfield, received a Silver Banksian 
Medal for a very attractive group of Cattleya 
Trianas, several varieties being of exceptionally 
good form. Well-flowered specimens of
