P- 53 - 
endrobium leucolophotum was originally described by Reichenbach, in 
1882, from specimens sent by Curtis from some part of the Malayan 
Archipelago to Messrs James Veitch & Sons, of Chelsea, during the pre- 
vious year. The précisé locality is said to be unknown. Prof. Reichenbach speaks 
of it as follows : — “ Very near D. barbatulum Lindl., 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 Wall., with triangular side laciniae rounded outside, 
and a linear ligulate acute long anterior lacinia. Ail 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 complété drawing of 
the plant having been forwarded by Messrs Linden, L’Horticulture Interna¬ 
tionale, Parc Léopold, Brussels, with the information that it came from 
Northern Queensland. It is quite identical with the plant mentioned above. As 
the précisé locality of the original plant is unknown, it seems quite possible that 
it may hâve, corne 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 région ! 
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
