not try such experiments ; though with any kind of shelter, as an 

 ordinary frame, most cool Orchids can be grown during the six 

 warmer months of the year. The principal experiments with Orchids 

 out of doors have been tried in Mr. A. H. Smee's garden, where large 

 numbers have been placed out from June to October with satisfactory 

 results, but this garden has a low moist situation, and is otherwise 

 favourable for the purpose. [See Journal of Horticulture, p. 392, 

 November 8th, and pp. 481 and 550, December, 1883.] Upon the 

 continent similar experiments have been repeatedly tried ; indeed it 

 is quite common there to place all but the most tender Orchids 

 outside in the summer. 



HAEDY ORCHIDS. 



The hints which have been previously given refer exclusively to 

 the exotic Orchids, which require to be grown in glass houses in this 

 country, but there is a large group of beautiful species, mostly 

 terrestrial, which can be cultivated out of doors. Amongst them are 

 several found wild in Britain, but none the less worthy of attention 

 on that account, though we owe the showiest to North America, such 

 as the beautiful rose and white Cypripedmm spectabile, which, when 

 well grown, is superior to many of its tropical brethren. Orchis 

 foliosa and maculata, with crimson and spotted flowers in dense 

 racemes, are also plants of great attraction, and admirably adapted 

 for culture in pots. We have plenty structurally interesting in the 

 genus Ophrys, which comprises the Bee. Spider, and Fly Orchids, and 

 many are also sweetly scented. The situation most suitable to the 

 greater number is at the foot of a rather shady bank or rockery, and 

 then the other species which are found on higher lands, and require a 

 chalky or sandy soil, can be accommodated upon the slope. For some 

 a constantly damp soil of peat, leaf mould, and a little turfy loam is 

 the best, such as Cypripedium spectabile, Epipactis palustris, Orchis 

 foliosa, O. latifolia, O. maculata, and 0. Stabiana. Another group 

 requires a slightly drier position and a small proportion of sand in 

 the soil, such as Calopogon pulchellus, Cephalanthera grandiflora, 

 C. rubra, Cypripediums acaule, Calceolus, candidum, japonieum, ma- 

 cranthum, and pubescens ; Epipactis latifolia, Goodyera pubescens, 

 Gymnadenia conopsea, Habenaria japonica, H. radiata, and H. 

 viridis ; Orchis mascula, papilionacea, and spectabilis ; Serapias 

 cordigeia, and longipetala. The third group require to be compara- 

 tively dry during winter, but moist at other times, though not wet 

 like the first named, and the soil should consist of loam or peat and 

 chalk. The best for this position are the following : Aceras anthro- 

 pophora, Habenaria bifolia, lutea, and chlorantha ; Neottia spiralis, 

 Ophrys arachnites, aranifera, apifera, Speculum, tenthredinifera ; 

 Orchis atlantica, coriophora, longicornis, militaris, pyramidalis, and 

 nndulatifolia. Some of those named for the cool house can also be
