emarginate smaller and wavy, white with rosy purple spots, 

 the disk being decorated with orange yellow crests. It is to 

 be regretted that this plant should prove difficult of cultiva- 

 tion, as it is one of the most beautiful Orchids we have seen 

 for many years. It blossoms during January and February. 

 We saw a fine variety of this plant in the collection of Baron 

 Schroder, The Dell, Staines ; and another with A. Sillem, 

 Esq., Sydenham, who has flowered three plants for two suc- 

 cessive years, and fine large varieties they were. Mr. Billiard 

 writes us as follows respecting their cultivation: — " Our plants 

 have been grown on the north-east side of a span-roofed 

 house, close to the glass, in a temperature ranging from 65° 

 to 70°. We keep the sun from them as much as possible. 

 They are potted in equal parts of peat and moss, with a 

 small quantity of sharp sand, and plenty of crocks and 

 charcoal as drainage. When making their growth they 

 delight in an abundance of moisture at the roots. We find 

 it necessary to sponge them weekly, as red spider, thrips, 

 and green fly are particularly fond of them. This year from 

 three plants we have four spikes, which have opened twenty- 

 three flowers. Last year the same plants had one spike each, 

 which gave us eighteen flowers in all." — Madagascar.

P. WallicMi, Lindley. — A large-growing plant of great 

 beauty, attaining some four or five feet in height, producing 

 its long upright racemes of flowers in March, April, and 

 May, and continuing to flower for six weeks. The plant has 

 entirely the habit of P. grandifoUus, having largish ovate 

 pseudobulbs, tufts of oblong-lanceolate nervose leaves, and 

 tall flower scapes springing from the side of the pseudo- 

 bulbs. The flowers are white externally, orange yellow or 

 bufi" suffused with reddish purple inside. The sepals and 

 petals are lanceolate, and as well as the cucuUate crispy- 

 edged lip much acuminate, the spur being curved and emar- 

 ginate. It makes a noble plant for winter blooming, and, if 

 retarded as directed for P. grandifoUus, is invaluable for 

 exhibition purposes. For further notice of these plants, see 

 chapter on Preparing Orchids for Travelling to Exhibitions. —
