Dendrobium leucolophotum. Aff. D. barbatulo LinpL., caule valido cylindrato attenuato polyphyllo; foliis 
oblongo-ligulatis acuminatis membranaceis ; racemo elongato laxifloro, mento acutangulo parvo; sepalis ligulatis 
acutis ; petalis oblongis acutis; labello trifido, laciniis lateralibus triangulis extrorsum obtusatis, lacinia mediana 
porrecta ligulata acuta, parte superiore supra nervos lamellis minutis ramulosis asperula ; columna minuta dorso 
apiculata. 
Dendrobium leucolophotum Reus. F. in Gard. Chron., 1882, pars 2, p. 552; VEITCH Man. Orch. Pl., pars 3, 
endrobium leucolophotum was originally described by REICHENBACH, in 
1882, from specimens sent by Curtis from some part of the Malayan 
j Archipelago to Messrs Jamzs Vuitcu & Sons, of Chelsea, during the pre- 
vious year. The precise locality is said to be unknown. Prof, REICHENBACH speaks 
of it as follows : — “ Very near D. barbatulum Linvt., but with a much 
stronger pseudobulb, a lax inflorescence exceeding a foot in length and much 
larger flowers of a fine white colour, apparently with yellowish buds. The acute 
chin is small, and the sepals ligulate acute, and far larger than the sepals. Lip 
trifid as in D. cuspidatum Watu., with triangular side laciniae rounded outside, 
and a linear ligulate acute long anterior lacinia. All the nerves of the superior 
half are covered with minute lobed lamellae, just as in D. barbatulum, whose 
conspicuous middle callus is absolutely unrepresented. ” 
The species appears to be extremely rare, but there is a raceme in the Kew 
Herbarium, received from Signor Commendatore H. J. Ross, of Florence, Italy. 
And now it has been re-introduced, a raceme and the complete drawing of 
the plant having been forwarded by Messrs Linpen, L’Horticunture INTERNA- 
TIONALE, Parc Leopold, Brussels, with the information that it came from 
Northern Queensland. It is quite identical with the plant mentioned above. As 
the precise locality of the original plant is unknown, it seems quite possible that — 
it may have come from the far east, and if so, the two localities are not so far 
apart as they may at first appear to be. It should also be remembered that 
D. Phalaenopsis occurs in Queensland, New Guinea, and Timor-laut, and 
D. leucolophotum may occur over an equally wide area. We know so little of 
the distribution of Orchids in this interesting region ! 
Although the plant has been very well compared with D. barbatulum, there 
are some decided affinities with D. Phalaenopsis. The long scapes and the gibbous
