The GuiAf^A Orchids. ii 



creeks, the Mourie and the mountain slope, are their 

 favourite haunts. After the Saman come the Flamboyant, 

 calabash, custard-apple and its allies, with all others that 

 allow sufficient light to penetrate. As a rule such trees 

 as the mango, tamarind and star-apple, are unsuitable, 

 although when kept well trimmed they may be utilised 

 for some species. It is always of advantage to have the 

 plants rather low, as they can be observed so much easier, 

 and in such a position they are better prote6led against 

 the wind. 



On trees, the most suitable orchids are undoubtedly the 

 two species of Oncidium (Lanceanum and altissimum) 

 and Cattleya superba. These flourish under conditions 

 most unfavourable to other species and will even endure 

 a fair sea breeze, although they undoubtedly succeed 

 better without it. After them come others, in something 

 like the following order, the most difficult to grow being 

 nearest the end of the list : — 



Brassia Lanceana Rodriguezia secunda 



„ Lawrenciana Burlingtonia Candida 



„ verrucosa Stanhopea eburnea 



Epidendron ciliare Catasetum tridentatum 



Gongora atropurpurea Brassavola angustata 

 Scuticaria Steelii lonopsis utricularioides 



These give no trouble whatever once they are placed on 

 a suitable tree, but go on flowering year after year, and 

 every season become better established. It will be 

 well however that they get an occasional spraying 

 with the hose or syringe, especially on the under sides of 

 the leaves, as they are subje£l to the attacks of several 

 inse6ls which can be often removed by such treatment. 

 It is also desirable to water the soil underneath in dry
