140 THE ORCHID REVIEW. (May, 1913 
A large number of other hybrid Odontoglossums were seen in bloom, and 
we were particularly struck with their sturdy growth, large firm bulbs, and 
the quality of the spikes and flowers, features that indicate the excellence 
of culture carried on here. Odontoglossums are not always seen in this. 
condition, and we asked Mr. Charlesworth for the minimum winter 
temperature of the houses. His reply was 52° F. for the established plants 
and 56° for the seedlings. We have seen lower figures advocated, and we 
are firmly convinced that a low winter temperature is one of the causes of 
failure in Odontoglossum culture. We took notes of many interesting 
things, but have not space to enumerate those seen in bloom. A number 
of capsules told of further progress in hybridising, and many interesting 
experiments are in progress. 
There are houses of seedling Cattleyas and Lzliocattleyas, in all stages, 
and we were much interested in some of the crosses, and particularly with 
the experiments being made to increase the number of yellow-flowered 
hybrids, which, however, proves to be a very difficult business owing to the 
amount of reversion to purple that takes place. A batch of seedling 
Cattleya Dowiana aurea was pointed out, obtained from the best forms of 
this Cattleya without hybridisation, and this should give some excellent 
yellow forms when the seedlings flower. Several fine Cattleyas and Lzelio- 
cattleyas were in bloom, and here, too, we noted some surprising examples 
of variation, particularly Brassolelia Gratrixie x Cattleya Octave Doin 
with both salmon-coloured and mauve varieties from the same capsule. 
Among the species many fine things were in bloom, and we can only 
enumerate a few of them. A plant of the handsome Oncidium Claesii was 
bearing a long trailing spike with ten side branches, and a large number of 
its handsome purple flowers. A lot of Trichopilia Backhouseana were 
coming into bloom and promise a very fine display. A batch of Oncidium 
concolor showed the effect of massing, and the result was brilliant. Some 
Cattleya citrina were in bloom, one of them having a twin-flowered scape. 
There were two plants of the distinct reddish Polystachya paniculata 
blooming well. Several plants of the charming little Miltonia Phalaenopsis 
were blooming freely, also a batch of M. Roezlii, while a house of M- 
vexillaria was a forest of spikes, and the plants in the most robust health. 
A promising seedling from M. vexillaria chelseiensis fertilised with M. v- 
memoria G. D. Owen was beginning to expand, and one could just see a 
large dark blotch on the lip. A fine lot of the handsome Phaius Norman, 
and a batch of Zygocolax Charlesworthii were also in bloom. 
But we must close our note book, for it is impossible to enumerateza 
tithe of the interesting features of this model establishment, and we must 
congratulate Mr. Charlesworth and his manager, Mr. Smith, on the 
progress and excellent culture that are everywhere apparent.
