Dendrobium. 



D. aggregatum (A',).v/'.).— A dwarf-growing species, not 

 exceeding 3in. or 4in. in height. The "pseudo-bulbs, each of 

 which bears a soHtary leaf, are crowded, angular, 2in. long, and 

 deep green. The flowers are clear yellow, becoming deeper 

 with age, the lip being dark yellow in front ; they are "borne in 

 arching racemes about 6in. long. This species blossoms during 

 iNIarch, April, and May. It is a native of Northern India and 

 Southern China, and first flowered in England in 1834. (B. M., 

 t. 3643.) The best variety is that known as inajiis. 



D. albosanguineum {Liiidl.). — This short, sturdy species has 

 stems Tjin. in diameter, and less than ift. high. Leaves lance- 

 shaped, 6in. long. The flowers, which grow two or three on a 

 scape, appear in ]\Iay ; they are very large (about 4in. across), and 

 of a soft creamy-white ; the petals, which are twice as broad as 

 the sepals, have a few blood-red streaks at the base ; and the 

 labellum has two large blotches of reddish-crimson in the middle. 

 During the growing season this plant requires sto^■e heat and a 

 thoroughly moist atmosphere. It is a native of the open hill 

 forests of INIoulmein. i^B. M., t. 5130.) 



D. amoenum (IFa//.). — A slender-growing plant. Pseudo- 

 bulbs about I ft. long, with short internodes. Leaves narrow, 3in. 

 long, deciduous. Flowers 2in. across, produced singly (some- 

 times two or three together) on the upper part of the ripened 

 leafless growths ; sepals and petals equal, white, tipped with 

 amethyst ; lip broad, notched at the margin, hairy in the throat, 

 coloured amethyst, with a white edge and a yellow blotch in front. 

 It blossoms in May, and is remarkable for its delicious violet-like 

 odour. It requires the same treatment as D. iiolnlc. Himalava, 

 1S74. (B. M., t. 6199.) 



D. atroviolaceum (Rolfe). — Allied to D. inacropliylliitn, this 

 delightful species was discovered by the late David Burk when 

 travelling as a collector for Messrs. J. A'eitch and Sons, in New- 

 Guinea, in 1S90. Sepals and petals creamy-white, spotted with 

 deep purple; lip violet-purple inside, green outside, three-lobed ; 

 spike terminal, erect. Pseudo-bulbs tapering downwards, persistent, 

 with two or three stout leathery leaves near the ape.x. (Fig. 61 ; 

 B. M., t. 7371; G. C, 1894, XV., p. 113, fig. 12.) 



D. aureum [Lindl.). — An easily - managed, very charming 

 Dendrobe. The pseudo-bulbs are from ift. to lift. high, 

 smooth, plump, as thick as the thumb in the upper half, yellowish 

 when old ; leaves lance-shaped, 4in. long, deciduous. Flowers 

 in twos or threes from the nodes of the two-year-old stems, each 

 one 2in. across; sepals and petals nearly equal, cream colour; lip
