ORCHIDS: HOW TO GROW THEM SUCCESSFULLY. 119 



house having an Intermediate temperature (but this is not necessary), 

 and brought back to the Warm house after blooming in April. The 

 flowers of this species are of good size, varying in number in proportion 

 to the strength of the plant, and the colour is of a rich purple tint. 



Good plants should be obtained at from 7s. 6d. to 10s. 6d. per 

 strong lead, imported or established plants. 



CATTLE YA ELDORADO. From Eio Negro. 



This is another handsome, delicate coloured species, which does 

 best in a little more warmth than that of the Intermediate house, and 

 it should be grown in pots placed on a shelf or in baskets suspended. 

 It flowers during the summer months and requires a high temperature 

 in the winter, so should not be removed from the Warm house. For 

 general treatment as to potting, watering, &c., see the section Cattleyas, 

 page 32. 



There is a variety of this species which is pure white and named 

 C. Eldorado Wallisii, and another C. Eldorado crocata, blush white 

 with a deep orange blotch in the throat, but the typical form is more 

 or less of a rose tint with an orange blotch in the throat, and the lip is 

 of a deep purple shade. 



Good plants of this species should be purchased at from 5s. to 

 7s. 6d. per strong leading growth, and in this case also it is preferable 

 to purchase newly imported or semi-established plants, taking great 

 care to preserve the native leaves as much as possible. 



CYPRIPEDIUM LAWRENCEANUM. From Borneo. 



The Warm house is really the home for the great majority of this 

 large genus, although there are some few species, as before stated, which 

 do well in a Cool house. This Cypripedium has two recommendations 

 in its highly ornamental foliage and handsome flowers, the greater 

 beauty of the latter centring in the dorsal sepal, which is white, 

 striped with a number of purple lines. It should be potted as advised 

 for Cypripediums (see page 35) and given a shady position on the stage, 

 with a liberal supply of water at all seasons, and, as this family of 

 Orchids is partial to a good deal of water, it is best that they should be 

 repotted at least once in every two years, otherwise the compost may 

 become too much decomposed and the drainage defective, and under 

 such circumstances the plants would not flourish. Should thrip attack 

 them a little tobacco powder dusted into the axils of the leaves will 

 Boon accomplish its destruction. 



This species flowers during the summer months, and good strong 

 plants are obtainable at from 3s. to 5s. per strong flowering lead. 



SELENIPEDIUM (CYPRIPEDIUM) SEDEN. Garden Hybrid. 

 This is a lovely and valuable garden hybrid, which continues 

 floAvering for some months from one stem, for when one flower is over
