THE ELOWER G-AEDE^. 



(See Orchis?) This peculiar branch of floriculture is mostly 

 pursued by persons who make it their especial study, 

 and whose practical experience is aided by treatises, 

 monographs, &c. C. calceolus. from the Alps ; C. gidta- 

 tum, from the cold regions of Canada, and also from the 

 forests of Siberia ; C. puoescens, from Carolina ; C. spec- 

 tcibile, also from North America, may be grown in heath- 

 mould, in the open ground, in a shady yet airy situation. 

 In winter they must have protection analogous to that- 

 afforded by a thick covering of snow. The great beauty 

 and singularity of the blossoms of the CypripeJ. 

 render them well worth the attention of those who are 

 not deterred by ordinary difficulties, and who will take 

 the trouble to carry out the Theory of Horticulture to 

 its practical and effective results. The plants on sale are 

 mostly imported, and therefore fetch good prices in the 

 horticultural market. L. Yan Houtte, of Ghent, Bel- 

 gium, advertises the very scarce and hardy C. macrantlium. 

 at two guineas each. 



Marvel of JPeru—jsIirabilis Jalcrpa — Belle de Nuit, or 

 Beauty of the Night, of the Trench. — This striking plant 

 requires a somewhat warmer and drier climate than our 

 own, and therefore does best in our hottest summers. It 

 then forms a bushy plant from two to three feet high, 

 covered with red, yellow, white, striped, or mottled 

 flowers, which open when the heat of the day is over, 

 and are succeeded by fresh blossoms the following day. 

 The Night-scented, or Long-flowered Marvel of Peru. 

 M. long if or a, differs from the above, in having a more 

 diffuse and brittle habit of growth, with heart-shaped 

 viscous leaves. The flowers, whose tube is from four to 

 five and a half inches long, are of a dull white, and emit, 

 after sunset, a powerful odour, which resembles a combi- 

 nation of orange-flowers and heliotrope. The varieties 

 of the first species, though differing in colour, are similar 

 in their growth and foliage ; and therefore should be 

 grown in beds or clumps by themselves alone, without- 

 being mixed up with the second species, which may be 

 planted singly, in rows, or in small groups of three or
