about 4 em. long and with comparatively large orange 
(yellow when dry) flowers. Stems 1—4 cm. long, 2-7 mm. 
in diameter, clavellate, swollen, with two to four articula- 
tions. Leaves on flowering specimens immature, elliptic- 
lanceolate, the largest seen about 25 mm. long and 6 mm. 
broad. Inflorescence 1-flowered, the flower apparently 
arising from the top of the articulation of the previous 
year’s growth, hence subterminal. Flowers large for the 
plant; mentum short and obtuse. Dorsal sepal 21-25 
mm. long, 8-4 mm. broad, linear-oblong, obtuse, 5- 
nerved. Lateral sepals 25-830 mm. long, 8.5-5 mm. 
broad, linear-lanceolate, acute, 5-nerved, shortly connate 
at the base and forming a mentum 4-5 mm. long. Petals 
25-30 mm. long, 2.5-4 mm. broad, linear-oblanceolate, 
obtuse, 5-nerved. Lip about 25-80 mm. long and 7-11 
mm. broad, entire, ovate-lanceolate, obtuse or acutish, 
with three lamellate ridges extending 7-8 mm. from the 
base, continued beyond the lamellae as papilliferous ex- 
crescences. Column about 2 mm. long; column-foot 
about 5 mm. long, with contiguous wings. 
Burma: rare epiphyte on Rhododendron, near Haka, at 1800 
meters altitude, flowers orange, April 28, 1938, Dickason 7779 (Typr 
in Herb. Ames No. 53685). 
There do not seem to be any closely allied species. 
Dendrobium Dickasonii apparently belongs in Kriinzlin’s 
section Superbienta of the subgenus Dendrocoryne.
