DENDROBIUM. 81 



and more slender, hence the two plants can be easily distinguished 

 from each other when not in flower; also the sepals and petals 

 of D. thyrsiflorum are white, but as there is a white variety of D. 

 densiflorum,* quite distinct from D. thyrsiflorum, it is the more 

 desirable that the latter should have a designation by which it may 

 not be easily confounded with the former. 



Dendrobium thyrsiflorum is a native of the forests of Moulmein 

 and of the Kargen district of Lower Burmah, and was introduced, 

 in 1864, by Messrs. Low and Co., through the Rev. C. Parish, its 

 discoverer. It flowers in April and May, and has, since its first 

 introduction, been regarded by horticulturists as one of the most 

 beautiful of the genus. 



D. tortile. 



Eudendrobium — Fasciculata. Steins club-shaped, attenuated below, 

 9 — 12 inches long, compressed, furrowed, yellow-green when old. Leaves 

 lanceolate-oblong, obliquely eniarginate, 3— 4 inches long. Flowers 3 

 inches across, in fascicles of twos and threes, but sometimes solitary, 

 produced from the uppermost joints ; sepals and petals narrowly oblong, 

 twisted, pale rosy lilac ; lip sub-orbicular when spread out, convolute 

 at base, pale primrose-yellow with a purple blotch at base, from which 

 some purple streaks radiate laterally. Column green, anther case 

 purple. 



Dendrobium tortile, Lindl. in Gard. Chron. 1847, p. 797. Bot. Mag. t. 4477. 

 Introduced by us, in 1847, from the Mergui district in Tenas- 

 serim, through Thomas Lobb. An inferior variety is also found on 

 the Arracan Hills. It is closely allied to Dendrobium primulinum 

 and D. Pierardi, but easily distinguished from both by its club- 

 shaped stems and twisted sepals and petals, the last-named peculiarity 

 suggesting the specific name. It flowers in June and July. 



D. transparens. 



Eudendrobium — Fasciculata. Stems slender, 12 — 18 inches lomr. 



Leaves linear-lanceolate, 3—4 mches long, deciduous. Flowers 1 \ inches 



in diameter, on purplish pedicels, in fascicles of twos and threes from 



the leafless shoots ; sepals lanceolate, white tinted with pale rosy 



mauve towards their tip ; petals elliptic-oblong, acute, similarly coloured ; 



lip ovate-oblong, with a short claw, which with the obscure side 



lobes is rolled over the column, white with two deeper purple stains 



on the disc, pale mauve-purple at the apex.
