D. Hodgkinsoni, Rolfe in Kew Bullet. ined. 
New Guinea, the native country of Dendrobium Hodgkin- 
soni, will probably prove to be the most productive of 
those hitherto unexplored areas of the globe which abound 
in Orchids. About a dozen species, many of them ve 
imperfectly known, are contained in Miquel’s “ Fl. Ind. 
Bat.,” published in 1859, to which must be added very 
many more recently discovered. 
D. Hodgkinsoni is, according to Mr. Rolfe, who has 
kindly given me his unpublished description of it, allied 
to D. atroviolacewm (tab. 7371) also a New Guinea species, 
from which it differs, amongst other characters, in the 
elliptic-lanceolate leaves, unspotted flowers, acuminate 
sepals, lanceolate petals, and the large callus on the disk 
of the lip. It was introduced by Messrs. Sander & Co., 
of St. Albans, from whom the Royal Gardens, Kew, 
obtained the specimen here figured, which flowered in 
1899. 
Descr.—Pseudobulbs tufted, five to ten inches long, 
narrowly clavate, deeply channelled. Leaves two or three 
terminal on the pseudobulb, four to seven inches long, ellip- 
tic-lanceolate, sub-acute, coriaceous, bright green. Scape 
terminal, erect, about four inches long, terminated by a
