ORCHID-GROWEE S MANUAL. 



P. TUBERCULOSUS, Blume. — A very handsome and distinct species, pro- 

 ducing short fusiform fleshy- stems, from which proceed the new growths 

 bearing a tuft of oblong-acuminate plicate leaves about a foot long. The erect 

 flower stems are produced with the young leafy growths and terminate in a 

 raceme of six or more flowers, which are each about 2^ inches across ; the sepals 

 and somewhat broader petals are pure white, and the lip, which is obliquely 

 funnel-ahaped, has the two broad side lobes yellow thickly marked with dull 

 crimson spots, which on the yellow ground produce a bronzy efEect, while the 

 front lobe is roundish 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 diflicult of culti- 

 vation, as it is one of the most 

 beautiful Orchids we have seen 

 for many years. It blossoms 

 during January and February. 

 The plants should be grown 

 in a temperature ranging from 

 65° to 70°, keeping the sun 

 from them as much as possible. 

 They should be 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 plant is well culti- 

 vated by Mr. Jaques, gardener to Baron F. de Eothschild, Aylesbury. —

P. WALLICHll, Lindl. — A large-giowing plant of groat bcautj-, attaining 

 some 4 or 5 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. grandifoliua, having largish ovate pseudobulbs, tufts of 

 oblong-lanceolate nervose leaves, and tall flower scapes springing from the side 

 of the pseudobulbs; the flowers are white externally, orange-yellow or buff 

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



PHAJUS TUBEECULOSUS.
