and D. grandiflora 3. It flowered for the first time in June, 1891, only 
twenty-one months after the seeds were sown, and received a First-class 
Certificate from the R. H. S. It most resembles the seed-parent, | both in 
shape and colour. 
D. X KEWENSIS (fig. By was raised at Kew, by Mr. Watson, frost 
D. grandiflora ¢ and D. tripetaloides ¢, and first flowered in May, 1893, 
only eighteen months after the seed was sown. The flowers most resemble 
those of the pollen parent in shape, and the colour is rose-pink, with a 
paler dorsal sepal, which is prettily spotted inside with rose- -purple. 
D. X LANGLEYENSIS (fig. 39) was raised both by Messrs. James Veitch & 
Sons and at Kew, at about the same time in both establishments, from D. 
racemosa ? and D. tripetaloides 3, and also from the reverse cross. It 
flowered for the first time in May, 1894, and received an Award of Merit from 
the R. H.S. The flowers are fairly intermediate in shape, and light rose- 
purple in colour, with a slight trace of spotting in some of the lighter forms. 
D. X PREMIER (fig. 36) is a secondary hybrid which was raised at Kew 
from D. tripetaloides ¢ and D. x Veitchii 3, and flowered for the first 
time in October, 1893, when it received a First-class Certificate from the 
R. H.S. The flowers are larger than those of D. racemosa, and rich rose- 
purple in colour. 
There are two or three other secondary hybrids in the genus. D. X 
Diores (D. X Veitchii @ x D. grandiflora 3), and D. x Clio (D. grandi- 
flora @ X D. x Veitchii 3) were both raised by Messrs. James Veitch & 
Sons, and the latter received an Award of Merit from the R. H.S. in 
August, 1898, and a First-class Certificate in July, 1899. It will be noted 
that the latter has the reversed parentage of the other, and is now con- 
sidered a variety of it. D. x Watsoni (D. x kewensis @ x D. grandiflora 
2) was raised at Kew, where it flowered about a year ago, and is much like 
an enlarged and improved form of D. x kewensis, hence it has also been 
called D. X kewensis superba, though of different parentage. Of the remain- 
ing one, raised in the collection of H. J. Elwes, Esq., it is a little doubtful 
whether the parentage was D. racemosa ¢ X D. X Veitchii ¢ or D. X 
kewensis 2 X D. X Veitchii g (Orch. Rev., vii., p. 226). 
These together form a very beautiful little group, but it will be observed 
that most of the possible combinations have already been effected, and it 
would be interesting to try the effect of introducing a little fresh blood, as 
several other species are occasionally met with in cultivation, and it would 
probably be possible to unite some of them with the preceding by hybridisa- 
tion if a few experiments were made. 
The cultural requirements of these plants are not difficult to supply. 
After flowering, a short period of rest should be allowed, but even during 
this period enough water should be given to Bee them plump and healthy
