ORCHIDS I HOW TO GROW THEM SUCCESSFULLY. 91 



sphagnum; it flowers in May or June, and the plant commences its 

 growth simultaneously with its flowering. Should it be necessary to 

 repot the plant, it must be done when the flower spikes begin to 

 appear, generally in the early part of March, for if left until they are 

 out of bloom both the new growth and the new roots are very far 

 advanced, rendering repotting at that stage both difficult and 

 dangerous. During the growing season water may be given rather 

 freely, but when a new pseudobulb has completed its growth it should 

 have a good period of rest, giving but little water during the winter, 

 and the plant should occupy a position on the stage near to the glass. 

 It is best to give this plant more warmth during the winter if possible. 

 Strong plants may be purchased at from 10s. to 20s. each, 

 established or semi-established. 



ADA ATJRANTIACA. From Ocana. 



This Orchid is recommended on account of its beautiful orange 

 coloured flowers, many of which are produced on each spike ; a few 

 plants in flower being very effective when arranged with other Orchids. 

 It flowers during the early spring months, and requires the same 

 treatment as the Odoiitoglossums, though probably a little less water 

 is required during the summer months, and it should occupy the warmest 

 end of the house, as its leaves become spotted on the under surface if 

 the temperature falls very low, and this should be avoided if possible, 

 as such a check often produces disease, seriously injuring and 

 occasionally causing the loss of the plant. 



Good plants, which under generous treatment soon grow into 

 good specimens, can be purchased at from os. to 10s. 6d. per two or 

 three leads.

CATTLEYA DOWIANA AUREA. From Antioquia. 

 This is the most beautiful of all the Cattleyas, having rich golden- 

 yellow flowers, with lovely purplish crimson veined markings on the 

 lip a charming and attractive combination of colours. It requires a 

 little more warmth than most of the other species, but the beauty of 

 the flower amply repays a little extra trouble; and, if available, a 

 position near the glass and immediately over the end where the hot- 

 water pipes enter the house, would suit it admirably during the 

 growing as well as the resting season. This grand Orchid should be
