76 DENDROBIUM. 



18 or more inches long, 8 — 12 or more flowered. Sepals narrowly ligulate, 

 acute, twisted, pale green with five brown nerves ; petals linear, 1 1 inches 

 long, 3 — 4 times twisted, brown with pale green margins ; lip pale yellow 

 streaked with purple, three-lobed, with five raised lines extending from 

 the base to the disc of the intermediate lobe, where they are confluent ; 

 side lobes rotund ; middle lobe subcordate with undulate margin ; spur 

 conic, acute. Column winged, white. 



Dendrobium Strebloceras, Rchb. in Gard. Chron. XXV. (1886), p. 266. Id. I. 



s. 3 (18S7), p. 140. 



A most curious Dendrobe, discovered by the Lindenian collectors 

 about the same time, and probably in or near the same locality as 

 the preceding species, to which it is nearly allied, and like it, 

 flowering in the autumn, the flowers persisting several weeks. A 

 sub-variety with whitish flowers, called Eossianum (Grard. Chron. III. 

 s. 3 (1888), p. 72), has appeared among the introduced plants. Both 

 the species and the sub-variety are in cultivation in the rich 

 collection of Dendrobes at Burford Lodge. The specific name is 

 literally "the crumpled horn," (arp£/3Xoc, fk twisted," and Ktpag } "a 

 horn "), and was suggested by the long twisted petals. 



D. sulcatum. 



Eudendrobidm — Calostachyce. Stems clavate, 7 — 10 inches long, 

 compressed and deeply furrowed, attenuated below, and bearing at their 

 summit 2—3 ovate-oblong, acute leaves, 3 — 1 inches long. Racemes 

 short, 10 — 15 flowered. Flowers orange-yellow, crowded; sepals oval- 

 oblong ; petals broader, ovate ; lip more richly coloured than the other 

 segments, broadly ovate, rolled over the column at the base, where 

 there are some reddish streaks.

 Chron. I. n. s. (1887), p. 607 (polyantha). Bot. Mag. t. 6962. 



One of the discoveries of Gibson, who sent it from the Khasia 



Hills to Chatsworth, in 1837, where it flowered for the first time 



in the spring of the following year. It is a less attractive species 



than the nearly allied Dendrobium densiflorum, from which it may 



be easily distinguished by its flattened furrowed stems, and shorter 



racemes of smaller flowers, which soon fade. 



D. superbiens. 



Stachyobium — Speciosm. Stems cylindric, slightly attenuated above 

 and below, 20 — 30 inches high,* leafy along the upper portion only. 

 Leaves broadly lanceolate, 3 — 4 inches long. Peduncles pseudo-terminal, 

 slender, nodding, dull green tinged with purple, racemose along the 



* In a wild state the stems are said to be often 3 — 4 feet long and as thick as a man's thumb.
