Native of the plains of Lower Burmah and Moulruein, where it 

 is very common. It first became known in British gardens about 

 the year 1825, through its discoverer, Dr. Wallich, who sent it to 

 Dean Herbert. The variety, which is found further north, was intro- 

 duced many years afterwards, and was at first considered specifically 

 distinct. The flowers of Dendrobium moschatum are among the 

 largest in the genus, but they are of short duration, lasting in 

 perfection scarcely a week. 



D. mutabile. 



Stachyobium — Speciosce. Stems slender, attenuated at the base and 

 apex, 8 — 12 or more inches long, leafy throughout. Leaves sessile, elliptic- 

 oblong, obtuse, gradually smaller upwards. Eacemes ten or more 

 flowered. Flowers crowded, 1 inch in diameter, white tinted with 

 rose; sepals ovate-oblong, obtuse; petals broader, sub-rotund, wavy; 

 lip broadly obcordate, threedobed, "with a deep notch at the apex, 

 and a raised yellow crest of three ridges on the disc near the base " ; 

 spur short, obtuse.

Discovered by the Dutch botanist Blume on the mountains of 

 Java, in the early part of the present century. The earliest notice 

 of it as a horticultural plant occurs in 1816, when it was in 

 cultivation in Mr. Rucker's collection at West Hill, Wandsworth, 

 and in the nursery of Messrs. Kollisson at Tooting, who had intro- 

 duced it. It is best known in British gardens under the nana' of 

 Dendrobium triadenium.
