flowers are preserved of this and previous dates in the 
Herbarium. In March of the present year, Mr. F. W. 
Burbidge sent flowers of this species to Kew for identifica- 
tion, and as it was flowering at Kew at the same time, the 
accompanying figure was made from the materials offered 
by the two establishments. - ee, 
Nearly six hundred proposed species of Dendrobium 
have been described, and it is estimated that about five 
hundred of them may be valid. They range from North- 
west India to Ceylon, China, Japan, the Malayan Archi- 
pelago, New Guinea, Australia, New Caledonia, New 
Zealand and Polynesia, eastward to Tahiti. The full 
merits of D. Wialliamsoni have probably not yet been 
brought out, and we can only add that it is very attrac- 
tive. ak 
Reichenbach compares the present species with his 
D. Draconis (Bot. Zeit. 1862, p. 914; B.M. t. 5459, under 
the name eburnewm). Other species of the same affinity ~ 
are: D. Lowii, Lindl. (B.M. t. 5303); D. infundibulum, 
Lindl. (B. M. t. 5446), and D. Wattii, Reichb. f(b. M. t. 
6715). 
Descr.—A caulescent species. Stems erect, rather thick, 
six to twelve inches high, many-leaved, more or less 
clothed, as well as the leaves, with black hairs. Leaves 
_oblong-lanceolate, three to four inches long, obliquely 
two-toothed at the tip, slightly overtopping the flowers. — eS 
Peduncles from the upper joints, usually two-flowered. 
Flowers two inches and a half to three inches across, 
ivory-white, or with a more decided tinge of yellow, and a 
zone of bright orange-red on the lateral lobes of the lip. — 
Sepals and petals similar, lanceolate, acute. Lip bearded; — 
lobes rounded, fringed, lateral smaller, erect, involute, 
terminal recurved. Anther hairy in front at the base. 
Column not hollowed in front.—W. B. H. 
Fig. 1, lip; 2, column and spur; 3, anther; 4 and 5, pollinia :—all enlarged.
