of the lip. It was introduced from the province of Thua-Thien, in Tonkin, 
by M. G. Bronckart.—Trib. Hort., i. p. 21. 
DENDROBIUM OCHRACEUM, De Wild.—Another Tonkin species discovered 
by M. G. Bronckart, but not yet introduced alive. It is said to be near D. 
Draconis, Rchb. f., but is much dwarfer. The flowers are white, striped 
with carmine on the lip.—Trib. Hort., i. p. 41. 
PAPHIOPEDILUM AFFINE, De Wild.—This also is from Tonkin, and is 
presumably of the same origin as the preceding, though this point is not 
recorded. It is said to be allied to P. villosum and P. dilectum.—Trid. 
Hort., i. p. 57. 
ANGR&CUM ARNOLDIANUM, De Wild.—Introduced from the Congo by 
M.S. Bieler, and flowered in the Jardin Botanique de-1’Etat, Brussels. 
It is evidently identical with A. Eichlerianum, Kranzl.—Trib. Hort., i. p. 83.

DENDROBIUM RHODOSTICTUM. 
ABOUT six years ago a pretty little New Guinea Dendrobium appeared in 
cultivation bearing the name of D. Madonne. It was introduced and dis- 
tributed by Messrs. Sander & Sons, St. Albans. In December, 1899, Messrs. 
Sander forwarded a living specimen to Kew, with a request that if the 
Species proved new the provisional name given should be adopted. On 
January 23rd, 1900, it received a Botanical Certificate from the R.H.S., 
when the name was recorded (Gard. Chron. 1900, i. p. 62; Orch. Rev. 1900, 
p. 61), and afterwards it was figured in the Botanical Magazine (t. 7,900). 
It now appears that it has an earlier name, having been described several 
years previously as D. rhodostictum (F. Muell. & Kranzl. in Oester. Bot. 
Leitschr, 1894, p. 300), from a dried specimen collected at Bouawarri, New 
Guinea, at 2,000 feet altitude, by Sayer. It was said to belong to the 
section Eudendrobium, and as there was no further clue to its affinity it was 
very unlikely to be identified with D. Madonne, which Lindley would have 
put in section Dendrocoryne, close to his D. Mooreanum, and the Genera 
Plantarum into the enlarged section Stachyobium. It is not a Eudendro- 
bium in any case, but as Dr. Kranzlin says that the two species are 
identical the determination must be accepted. Another ally is D. Fairfaxii, 
Rolfe, a native of the New Hebrides. D. rhodostictum takes its name from 
the numerous purple spots on the front margin of the lip. It is a very 
floriferous little plant, growing and flowering freely under the treatment 
given to D, Phaleznopsis, D. atroviolacum, and other species from New 
Guinea and the adjacent region. It has much of the general habit of D. 
atroviolaceum, Rolfe, which also belongs to the same group, though the 
two differ much in the colour of the flowers. . ROLFE.
