 t. 155. Bot. Mag. t. 5520. 



Discovered by the Kev. C. Parish in Moulmein, and sent by him 



to Messrs. Low and Co., in 1864. The plant is singular among Den- 



drobes from its being clothed with long woolly hairs like some of 



the Cereus, and which suggested its specific name (senilis, literally, 



"resembling old age 5 '). The flowers are nearly as large as those of 



Dendrobium chrysanthum, and are produced in the spring months. 



It is best cultivated on blocks suspended near the roof glass. 



D. speciosum. 



Stachyobium — Specwsce. A robust plant. Stems clavate, 9 — 12 inches 



long and l£ inches thick, bearing at their apex 3 — 4 coriaceous 



elliptic-oblong leaves 8 — 10 inches long, and 2^ — 3£ baches broad. 



Peduncles two or more from each stem, pseudo-terminal, 20—30 inches 



long, marked with longitudinal ridges and furrows, and bearing a 



somewhat dense raceme of pale buff-yellow fragrant flowers. Flowers 



small, never fully expanding ; sepals lanceolate, acuminate, the lateral 



two falcate ; petals linear-lanceolate ; lip shorter than the other 



segments and almost enclosed by them, oblong with the sides 



turned upwards, truncate at apex, and with a notch at each lateral 



margin, making it obscurely three-lobed, pale yellow spotted with purple. 



Column short, white, spotted with purple on side facmg the lip.

 the base.
