208 THE ORCHID REVIEW. 
essential particulars. It was sent from Colombia by Consul F. C. Lehmann, 
who thought it new. The flower, in point of size and shape of the perianth, 
rather inclines towards A. uniflora, but the colour is light yellow, slightly 
paler than in A. Clowesii, but with the addition of numerous minute red 
dots so characteristic of the species first named. The column and lip, 
however, are most like A. Clowesii in their essential details, and agree well 
with the characters pointed out by Reichenbach. The lip is white, with 
many red-brown dots on the lower part of the lobes, which are more or less 
confluent intoa blotch. Its re-appearance is interesting, and I hope that 
some of these days we shall hear of an artificially raised hybrid between the 
two species. It has long been known that the three species of Anguloa, 
Clowesii, Ruckeri, and uniflora, grow in the same district, and it is rather 
singular that all the three possible hybrids between them have appeared, 
either as natural or artificial hybrids. . All the hybrids seem to be very rare.

‘DENDROBIUM x WALTONI. 
WHEN a note on thevhistory of Dendrobium x Waltoni was given about 
a year ago (Orch. Rev. viil., p. 177, fig. 29), the question of its first 
appearance was not quite settled. It was traced back to April, 1879, when 
Reichenbach hinted at an earlier appearance, for he remarked, “I have a 
remembrance of Mr. Borwick (of Walthamstow) having spoken of a hybrid, 
even having sent flowers. I was then as incredulous as St. Thomas himself.” 
The point is cleared up in a letter received from Messrs. Hugh Low & Co. 
in February, 1891, which has been overlooked. The plant had then been 
known for fourteen years, having appeared in the very first importation of 
Dendrobium Wardianum Lowii received by them in 1875, and it was first 
flowered by. Mr. Walton, gardener to Alfred Borwick, Esq., Higham Hill, 
Walthamstow. It is suggested that the name D. x Waltoni was given by 
Reichenbach, though it appears not to have been published until 1885, when 
a note appeared in the Garden (xxvii., p. 119), presumably from the pen of 
the late Mr. Gower. This point it might be difficult to clear up, unless the 
original ietter could be found, or some evidence exists in the Reichen- 
bachian Herharium. The uncertainty about its origin might easily account 
for some delay in publication, but further evidence came to hand in due 
time, and when, in 1892, Messrs. James Veitch & Sons flowered artificially 
raised seedlings, all doubt about its being a natural hybrid between D. 
crassinode and D. Wardianum vanished.
