﻿THE ORCHID REVIEW 



most species of Cattleya from the Alpine re-ions of South America thrive 

 under the existing conditions of the house, while those requiring a degree 

 or so more warmth, or vice versa, can generally be accommodated at the 



warmest or coolest end as required. The temperature should now be 6o°, 

 a few degrees more during the day, and a few less at night. 



The Intermediate house is one having a temperature intermediate 

 between the Cattleya house and the Cool one, and is better suited to the 



L. autumnalis, L. grar.diflora (majalis), &C, and it is a wise plan to he 

 such a house, as these plants are great lovers of sunlight, but where 

 separate house is not provided they can generallv be found a place 

 themselves in the Cattleya house. 



Having noted the various departments, it will be wise to take a glance 

 through them, noting what is in bloom and the condition and treatment 

 required by the general occupants. 



In the Cool house we first note that Odontoglossum crispum, Pescatorei, 

 constrictum, Sanderianum, and others of this section, have various members 

 of their respective species in bloom, whilst others are in full growth. The 

 latter will require to be kept moister at the root than those in bloom, or 

 nearly so, but providing the proper amount of moisture be present in the air 

 none of the plants should be given water enough to keep the compost in a 

 sodden condition. In flower we have O. Rossii and O. Cervantesii hanging 

 overhead, and although these appreciate moisture, they should not be 

 dipped immediately the material shows signs of becoming dry. Epidendnnn 

 vitellinum is also in this house, and gives a brilliant effect when in 

 bloom. The plants are now at rest, and should only have water given 

 them at long intervals, otherwise the leaves will turn yellow and fall off. 

 Ada aurantiaca, though of a different character, produces flowers of a 

 similar hue ; the plants are now in full growth, and therefore should have 

 plenty of water at the root. Oncidiums are also represented here, such as 

 O. varicosum, now at rest, and hence to be kept on the dry side ; O. 

 Marshallianum, just commencing to grow, and thus requiring more water, 

 though, as a rule, this plant produces more roots when kept slightly on the 

 dry side at this season. O. incurvum succeeds when given the same treat- 

 ment as Odontoglossums. In the case of O. olivaceum, now pushing up its 

 spikes from the perfectly made growths, guard against over-watering the 

 plant, or the spikes may damp off. 



Masdevallias are, I regret to say, not so popular as formerly. They 

 require to have a few degrees more warmth at this season than that given
