DE>IDROBIUM. 351 



D. MUTABILE, Lindley. — A very pretty evergreen species, with rather slender 

 terete erect striated stems, furnished with numerous distichous elliptical sessile 

 blunt fleshy leaves, which become smaller upwards, the stems terminating in a 

 dense panicle of medium-sized flowers, which are in some forms white, and in 

 others white tinted with rose; the lip is deeply emarginate or obcordate, and 

 bears on its disk three crests, which are blunt at the apex and tinted with yellow 

 or orange. The flowers are produced on the leafy stems at different times of the 

 year, and last two weeks in bloom. It is best grown in a pot with peat. — India.

D. NESTOR, O'Brien. — A hybrid -between D.Farishii and D. anosmuvi, raised 

 and flowered by Charles Winn, Esq., of Birmingham. "The expanded flowers 

 are 3 inches in diameter; sepals and petals white, tinged with rosy-lilac; lip 

 white at the base, streaked with purple, which at each side of the median portion 

 of the lip merges into a large bright purple blotch, the margin and front of the 

 lip being pale rosy-lilac ; like the petals, the edge and surface of the lip are 

 pubescent, and the flowers have an odour resembling medicinal rhubarb, a 

 peculiarity common to this section of Bendrohes" (J. O'Brien, in Gardeners' 

 Chronicle, 3rd ser., 1892, xi. p. 718). — Garden hyh-id.

D. NOBILE, Lindley. — A magnificent and justly popular free-flowering ever- 

 green species. The erect furrowed stems are a foot or more in height, clustered, 

 terete, compressed, slightly, thickened upwards, bearing distichous oblong obli- 

 quely emarginate leaves, and on the older ripened stems clusters of two or three 

 flowers from the upper nodes; the blossoms are rather large and very showy, with 

 oval sepals and much broader undulated petals, 

 white heavily tipped with rose, the lip rolled up 

 at the base, downy on both surfaces, roundish 

 ovate, creamy white with rosy tip, and a deep 

 crimson spot in the throat. It blooms during 

 the winter and spring months, lasting three 

 or four weeks in good condition if kept in a 

 cool house. It will grow either in a pot • or 

 basket, with moss or peat. This is one of the 

 finest exhibition plants we have ; but to keep 

 it for exhibition, it must be put in the green- dexdeobium mobile. 



house, shaded from the sun, and left there till 



it is wanted, when it must be forced into bloom. During the time it is in a cool 

 house give it but little water, only enough to keep it from shrivelling. This 

 species may be had in full flower from January to June by procuring a number 

 of plants and treating them succession ally. — India; China.
