green, and soon form noble specimens, producing an abundant 

 supply of flowers in winter and spring. A noble plant of this 

 species bore thirty-six fine spikes at Chatswortb, in 1871. It 

 is a native of Hong Kong, growing in moist localities. Leaves 

 from two to three feet long, broadly lanceolate ; flower-scapes 

 from two to four feet high, many flowered ; flowers from three 

 to four inches across ; sepals and petals lanceolate, of s 

 brownish colour within, white without ; lip convolute, white, 

 with a dark crimson-brown throat. The spikes of this free- 

 flowering species are well adapted for cutting. January ta 

 March, lasting six weeks. 



P. Wallichii (India). — Khasya hills in sheltered positions. 

 A vigorous growing plant, similar in habit to the last, bearing- 

 tall spikes, from three to five feet high. Flowers from four to 

 five inches across, of a warm brown colour ; lip yellow, with a 

 brown throat. Lasts six weeks in beauty, blooming a montb 

 later than the last. 



Pilumna. 



*P. fragrans. —This is a very beautiful white-flowered Orchid ,. 

 nearly related to the Trichopilias. Its pseudo-bulbs are flat> 

 from four to seven inches high, bearing a dark green leaf. 

 Flowers from two to four on a stout spike ; sepals and petals 

 pure white ; lip also of snowy whiteness, having a spot of 

 bright orange on its disc. The plant figured in the Botanical 

 Magazine under this name is not nearly so good as this plant, 

 and is in all probability another green sepaled species. Messrs. 

 Backhouse & Sons, of York, have been successful in obtaining 

 a good importation of this deliciously perfumed plant, which 

 will soon become a favourite in our collections. It grows 

 freely treated like the Trichopilias with a good supply of 

 moisture when growing.
