326 THE ORCHID REVIEW. [NovEMBER, 1923- 
feet, it is a true forest plant and much less hardy. Pescatorea cerina and 
Huntleya Burtii are comparatively rare. 
Like the correspondent in Assam (p. 162), I have a house, recently 
erected, of somewhat similar design, not yet sufficiently tested, in regard to 
shading, for fitness to the Cartago climate, and I hope to exchange plants 
with him. Our costal species would probably be at home there, though 
they have never experienced either of the extremes of temperature he 
mentions. Our shade maximum is probably 74° and minimum 52° at 4,800 
feet, though neither of these figures are frequently attained. Conditions 
here are favourable to most Colombian plants. Cattleya Triana and C. 
Warscewiczii do very well. I have failed with the Venezuelan Cattleya 
Lueddemanniana and C. Mossi, and C. labiata does not do really well. 
The majority of hybrids are quite at home, once they become established, 
and a large range of other genera may be grown successfully with them. 
OrcHID CULTURE IN Costa Rica.—From C. H. Lankester, Esq., 
Cartago, Costa Rica, we have received a photograph of a large shed well- 
filled with Orchids, and having the roof constructed of laths so as to admit: 
sufficient light for the well-being of the plants. In an accompanying letter, 
Mr. Lankester says: ‘‘ This shed is an experiment in Orchid growing in 
Cartago. I hope it will look better when the longitudinal roof-wires are 
well laden with hanging baskets. Our usual period for rainy weather has 
this season been exceptionally dry, and watering has been necessary. The 
article on Zygopetalums (p. 182) interested me. I should have thought 
these plants presented little difficulty in culture at home. I am sure many 
of them would do well in an ordinary fern conservatory. But certain 
Orchids are baffling plants, and it must be confusing when occasionally a 
member of a genus usually growing at high and moist altitudes is found on 
the coast. For instance, the Warscewiczellas of Panama. A notable 
example here is Odontoglossum Krameri, which is found so low as 1,000: 
feet, and should be grown with Cattleya Dowiana. That also is a rather 
difficult, but not exceptional, plant to cultivate ; it has the deep zonal range 
of from sea-level to 4,200 feet.” 
ScuTICARIA STEELEI.—This species was introduced from Demerara in 
1836 by Mr. M. Steele, and was again found by the brothers Schomburgk. 
during their exploration of British Guiana in 1840-44 growing on the banks 
of the rivers Essequibo and Demerara on the trunks of trees, flowering in 
June and July. The stems are as thick as an ordinary writing pencil, about 
two inches long, the pendulous leaves being as thick as a swan’s quill and 
often exceeding two feet in length. The flowers are nearly three inches im 
diameter, light yellow spotted with red-brown.
