﻿September, 1904.] THE ORCHID REVIEW. 259 



Odontoglossum Rossii and O. Cervantesii are two very handsome 

 Mexican species of very easy culture, but being rather dwarf they succeed 

 best in pans suspended from the roof, leaving a clear foot between the 

 foliage and the roof. The plants should be grown as strongly as possible, 

 when they flower freely and are very effective. O. maculatum, O. 

 cordatum, and O. pulchellum are rather larger, and may be grown in pots on 

 the stage, but all require practically the same treatment as O. crispum. 



Several charming Oncidiums are worthy of selection, as the Mexican O. 

 tigrinum, and the Ecuadorean O. macranthum. the latter hav ing a rambling 

 inflorescence, which may either be tied along a wire, or trained round two 

 or three neat sticks inserted in the pot. Its large bright yellow flowers are 

 very handsome, but care should be taken not to let the plant weaken itself 

 by over-flowering. O. Marshallianum and O. Forbesii are two handsome 

 Brazilian species which should not be overlooked, while a similar remark 

 applies to O. crispum and O. varicosum Rogersii. These Brazilian species 

 may be kept rather drier when at rest, and should be kept in the warmest 

 part of the house. O. incurvum bears a large branching inflorescence of 

 white and purple flowers. O. cheirophorum with bright yellow and O. 

 ornithorrhynchum with purple flowers are dwarfer species, and succeed best 

 in hanging pans like Odontoglossum Rossii. 



A really brilliant Cool house Orchid which should be included in every 

 collection is Sophronitis grandiflora, which succeeds well in hanging pans 

 in the usual compost, and flowers freely during the winter months. It 

 should be kept in the warmest corner of the house, and always be kept 

 moist, and shaded from bright sunshine. Laelia pumilaand L. Dayana will 

 succeed under similar conditions, and are almost the only other species of 

 the group that will succeed with Odontoglossums. Very little water is 

 required during the winter, but the compost should be kept just moist. 



Epidendrum vitellinum is a Mexican species, having brilliant cinnabar- 

 orange flowers, which requires cool treatment, as it comes from a high 

 altitude. It succeeds well in hanging pans, in the coolest part of the house, 

 and should be potted about March, and encouraged to grow freely, for the 

 spikes soon begin to push, and the flowers appear during the early summer. 

 During winter it should be kept rather dry, as the leaves are liable to spot 



No Cool house collection is complete without a few Masdevallias, and 

 among the best must be mentioned M. Veitchiana, and the varieties of M. 

 •coccinea. M. ignea and M. Davisii may also be included. They require 

 very similar treatment to Odontoglossums, but need very careful watering 

 during winter, as having no pseudobulbs they suffer if kept too dry, while 

 over-watering may cause them to lose their leaves. 



Anguloa Clowesii is another remarkable Orchid that may be successfully
