THE ORCHID REVIEW. 37 
constantly growing, more or less, and the bulbs do not seem to ripen at all. 
One of our specimens flowered some years ago, shortly after its importation, 
but never since. 
The Orchids cultivated here are mostly natives of India, and the 
following genera are well represented: — Dendrobium, Coelogyne, 
Cypripedium, Bulbophyllum, Eria, Eulophia, Geodorum, Cirrhopetalum, 
Phaius, Cymbidium, Renanthera, Saccolabium, Vanda, &c., the majority of 
which are more of botanical interest than decorative, though the display 
obtained from some of them during the months of March and April is really 
grand. Cypripedium Spicerianum and venustum, and those of the concolor 
and bellatulum group, are really the most successfully grown in our 
latitudes. Such species as C. Boxalii, villosum, and insigne, are practically 
rebels to cultivation here. 
The species of Phalznopsis do well here, and 18-inch leaves are of 
common occurence. Amongst the most successful varieties let me 
mention P. Schilleriana, amabilis, and tetraspis. 
As will be seen by the above notes, the collection embraces a few 
representatives of South and Western America, mostly Cattleyas, Lzlias, 
Epidendrums, and Oncidiums. A few species from Tropical Africa are 
also grown, with a few from Madagascar, and as many representatives of 
our Asiatic flore >< cultivation permits. 
According to tne last catalogue of plants cultivated in these gardens, 
the Orchid collection is represented by some 350 species, belonging to about 
35 genera, and a few hybrids. It has since increased but slowly, and the 
difficulties previously described must account for it. 
Respecting the mode of cultivation, our Orchids are grown in much the 
same way as in Europe. As a rule, very little soil oi ~»mpost is used. 
Saccolabiums, Aérides, Vandas, Acampes, and all this class, are mostly 
grown on blocks. A few of them are sometimes met grown in pans, in 
which case they are simply fixed amongst the drainage. A very thin top- 
dressing of moss is generally given before the summer, so as to secure to 
the roots a certain amount of moisture, but it has to be removed at the 
beginning of the rains, to allow the roots to assimilate the excessive atmos- 
pheric moisture. 
Plants grown on blocks are syringed several ti 
also, are successfully cultivated on blocks, large kinds, such as D. 
pulchellum (Dalhousianum), moschatum, fimbriatum, &c., are generally 
grown in pans. Phalenopsis do very well grown on fern stem rafters. 
Terrestrial species, as Eulophia, Phaius, Geodorum, &c., are grown 1 a 
kind of light loam, with a very good drainage; also Cypripediums. 
Ancectochilus are grown simply in moss and sand. Vanda teres and 
Hookeriana are always fixed to some big pieces of wood, fastened in pots, 
mes daily. Dendrobiums,
