D. Hookerianum. 



Eudendrobium — Calostachyce. Stems rod-like, 6 — 8 feet long, swollen 

 at the base into small pseudo-bulbs. Leaves oblong-lanceolate, acuminate, 

 4 — 6 inches long. Flowers 3 — 4 inches across, in pendulous racemes 

 of 9—12 or even more on each, borne on the leafing stems and also 

 on the older leafless ones, bright golden yellow, with two maroon spots 

 near the base of the lip ; sepals and petals similar, oblong, acute ; lip 

 with a convolute claw and broadly oval limb, which is velvety on the 

 upper surface and fringed at the margin. Column short, whitish.

A superb species first discovered by Sir Joseph Hooker, ' c in 

 Sikkim, in 1848, growing on trees in hot valleys at an elevation 

 of 1,000 — 5,000 feet above the level of the sea." It was introduced 

 by the late Mr. John Day, who informed us that it is also a 

 native of the Assam Hills, where it was discovered by his nephew, 

 Captain Williamson, who first sent it to England in 1868, and again 

 in several succeeding years; it appears to be plentiful in the place 

 where it grows. It flowered for the first time in this country in 

 the horticultural establishment of Messrs. Brooks and Co., at Man- 

 chester, in September, 1870, the plant being one of those received 

 by Mr. Day, who had, however, himself been unsuccessful in flower- 

 ing any of the plants retained for his own collection at Tottenham ; 

 a difficulty frequently experienced by other cultivators. Its nearest 

 ally is Dendrobium fimbriatum, from which it differs chiefly in its 

 larger flowers, that are borne on leafing stems and appear at different 

 seasons of the year, and in the almost equal sepals and petals 

 with entire margins. 



D. Huttonii. 



Eudendrobium — Fasciculata. Stems slender, erect, 20 — 30 inches 

 long, leafy along the upper half. Leaves sessile, linear-lanceolate, acute, 

 3 inches long. Flowers solitary, or in fascicles of twos and threes 

 from the uppermost joints, white bordered with purple, the border on 

 the lip deeper in colour than on the other segments; sepals and petals 

 oval-oblong ; lip obovate-oblong ; spur cylindric, obtuse. 



Dendrobium Huttonii, Rchb. in Gard. Chron. 1869, p. 686. 

 A native of Timor, in the Malayan Archipelago, where it was 

 discovered by the late Henry Hutton, while collecting for us in 1868.
