JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. 



trees, thin as they are, yet give some shade, grow Catasetums of 

 more than one species, as well as a Brassia, perhaps unnamed, 

 but certainly not beautiful enough to be an acquisition to 

 gardens. And in the deeper shade grows one of the rare 

 terrestrial Orchids of Guiana, a Microstylis. 



Outside the clumps of trees, but where the shadow of these 

 occasionally falls, are thickets of a Cyrtopodium with gigantic 

 pseudo-bulbs, often three or more feet long, over which rise the 

 splendid masses of yellow flowers. 



I have left myself no space to speak of the forest country 

 further inland, or of the open highlands, to which the name of 

 savannah more especially belongs, yet further in the interior. 

 If the Orchid pictures which have already been given are of any 

 interest to the readers of the Society's Journal, possibly the 

 editor will allow me on a future occasion to tell of the homes 

 of the Cattleya and Selenipecliums (of both of which genera, 

 however, there are but few species in Guiana), as well as of my 

 own greater favourites, Trichocentrum, Quekettia, Octomeria, and 

 so on. 



I cannot, however, close the present paper without justifying 

 my appearance in a journal of this nature by one suggestion 

 which I suppose may be picked out as the one practical point of 

 what I have here written. 



I have found by experience in my own garden (which it must, 

 however, be remembered is in the tropics) that a great many 

 small Orchids which it seems difficult or impossible to establish 

 in pots or on blocks, or in any of the ordinary methods of the 

 garden, can be established very readily — so readily that in the 

 tropics they soon seed themselves freely over the garden — on 

 growing plants of garden shrubs. Such shrubs as the various 

 species of Taberncemontana, Jasminum, Gardenia, Hibiscus, 

 Coffea, and even " Crotons," make suitable hosts for Ionopsis 

 paniculata, as also for the much rarer I. teres, for Oncidium 

 iridifolium, Bodriguczia (including Burlingtonia Candida), and, 

 in short, for most of those which grow naturally on the outer 

 branchlets of trees or shrubs, and are consequently much exposed 

 to the sun, and are at the same time provided with ideally 

 perfect drainage. The conditions in an English stove of course 

 differ very materially from those of a tropical garden; but it 

 would perhaps be worth the experiment whether some of the 

 small u difficult things " might not be grown on living hosts.
