162 THE ORCHID REVIEW. [JUNE, 1907 
those produced in the later years. In the last two flowerings the blotches 
have gradually become united, until each of the segments has becomea solid 
mass for more than two thirds of its area, while the tracing of colour 
indicates a probability of further development in this respect. The colour 
is almost crimson-purple, the white marblings being suffused with violet- 
purple. O.c. Britannia, considered to be one of the most beautiful in the 
collection, will shortly be in flower. There were also numberless interesting 
seedling Odontoglossums, with some Odontiodas. We were particularly 
struck by the healthy and vigorous appearance of all the Odontoglossums, 
in fact, here they seem to grow like weeds. 
Among many seedlings we may note a few interesting crosses. Odonto- 
glossum crispum Cooksonianum X O. c. Cooksoni#, O. c. Mundyanum 
x O. c. Chapmanii, O. c. Graireanum X O. c. Prince Leopold, O. 
Pescatorei Charlesworthii x O. crispum Graireanum, and Cochlioda 
Noetzliana X O.crispum Graireanum are all doing well. There were, in 
fact, seedlings of all the best crispums intercrossed, both here and in the 
Odontoglossum houses. Mr. Cookson has not been afraid to use his best 
forms to carry seed on. C. X Dom Carlos Rex (Godefroye leucochilum X 
Lawrenceanum) is just showing flower, as also are numerous hybrids, due 
to the intercrossing of various sections of albinos. 
One house is devoted to Phaius and Cypripediums. The P. simulans 
section is represented in all the known varieties. They do remarkably well 
here. The plants are often used for decorative purposes in the house, for 
as much as six weeks at a time. The P. Humblotii section, represented by 
P. X Cooksoniz, P. x oakwoodiensis, P. x Phoebe and P. x P.superbus, 
are just expanding their flowers. 
Phaius Humblotii itself is also coming into bloom. We also noted P. 
x Ruby, P. X Chapmanii superbus, and others, as yet unnamed, and 
flowering for the first time. An interesting secondary cross is between P. — 
x Norman and P. Blumei. This had reverted almost to Blumei, having 
the sepals and petals of the latter. Asin P. x Norman, there is remark- : 
able variation in plants from the same seed pod. The temperature of this 
house is practically intermediate. There are also included the wintef- 
flowering section of Cypripediums, represented by large specimen plants of 
most of the best-known kinds, hybrid and species, C. Fairrieanum and 1ts a 
hybrids being fully represented. We saw magnificent plants of most of the , 
well-known hybrids that have originated here. 
The Dendrobium house includes the best-known species, while the 
hybrids represented are chiefly those that have been raised in the collection 
The Calanthe house contains a fine collection of this genus. These are |
