entire length of the stem, which sometimes attains the extent 

 of four feet ; they are two inches across ; the sepals cream- 

 coloured, shaded with pinkish purple ; the petals are broader 

 than the sepals, and are pink, with a deep purple stain ; the 

 lip is broadly heart-shaped, white, rich purple on the edges, 

 with two spots of rich orange on the column, and the entire 

 margin is most beautifully frilled. It blooms in May or June, 

 lasts two weeks in perfection, and is best grown in a basket 

 with moss. This plant is usually found difficult to cultivate ; 

 but the great secret is to give it plenty of water when growing,

 searched for, and, if found, kept under by syringing the

 a splendid plant for exhibition. Native of Moulmein, &c. 



P. Devoiiianum rhodoneurum. — This variety is said to last 

 longer in flower than the normal form. The sepals and petals 

 are streaked with dark purple ; Hp large and round ; it is

D. eri/throxanthum. — In habit of growth this species

 clusters of two to three dozen, blooms in August. 



D. dixanthum. — A very pretty species from Moulmein; it 

 is a very free grower and abundant flowerer, producing its 

 flowers, which are two shades of yellow, in spring. 



D. Falconer ii. — A magnificent plant, and one of the most 

 beautiful of the genus ; it is a pendulous grower, and so diffi- 

 cult to cultivate that only a few have succeeded well with 

 it. Last year there were large importations received by 

 Messrs. Low, and growers will have a better chance of 

 finding the best way to cultivate it by placing it under dif- 

 ferent treatment and in difi'erent houses. During the growing 

 season it likes a good supply of water; but after it has
