In the Normanhurst Collection. One of the most beautiful Odontiodas raised. 
SOME INTERESTING CYPRIPEDIUMS. 
A VERY interesting series of fifteen Cypri- 
pedium flowers is kindly sent by C. J. Lucas, 
Esq., Warnham Court, Horsham. The plants 
from which these flowers have been cut are 
seedlings raised from Cyp. Julia and Cyp. 
Boxallii, the former parent being a hybrid 
between Law/enceanum and exul, but having 
the shape and markings of exul to such an 
extent that almost all trace of Lawrenceanum 
is eliminated. 
In Boxallii the purple spotting of the dor- 
sal sepal is on a yellow ground ; this com- 
bination produces the dark brown congested 
spotting which is so- characteristic of the 
species. Many of these hybrids, while still 
maintaining much of this dorsal spotting, have 
also inherited the white dorsal sepal of exul 
to such an extent that the spotting, instead of 
being on a yellow ground, is now on one of 
pure white, thus showing to the best advan- 
tage the pure rich purple which before was 
created into brown by the influence of the 
yellow. 
The amount of spotting varies ; in some 
flowers very little is to be seen, while in 
others the confluent spotting is quite equal to 
the amount usually seen in Boxallii. 
In one flower the purple pigment of Boxallii 
has created a rose-flushed dorsal sepal. This 
is unusual, but has occurred in other cases 
w'here this species has been used in combina- 
tion with others having a white ground, the 
best instance of this being Cyp. Mrs. Wm. 
Mostyn, in which Spicerianum takes a large 
share in the parentage. 
Four flowers, apparently of the same cross, 
have assumed a watery or hyaline condition. 
This " glassiness " is probably the result of 
some unfavourable climatic condition of the 
house in which they are growing, either an 
excess of moisture or too low a temperature. 
It has also been recorded as having occurred 
in the flowers of Cattleya labiata, a few of 
which were affected in this way when stand- 
ing above a large rain-water tank, all the 
flowers in the other portion of the house 
remaining perfect. The cause is probably a 
transfusion of the cell-sap into the intercel- 
lular spaces. .Some species appear to be 
more susceptible to this physiological con- 
dition than others.
