112 THE ORCHID REVIEW. [APRIL, 1903+ 
in one part of the house, they will, for some reason or other, grow well in 
some other part of the same structure. This must be observed, and when a 
plant is not at home in one place try it in another, and when you have 
found the place that suits it, keep it there. The chief elements of success 
in Orchid growing lie under these heads:—The proper temperature 
according to season; proper watering; and perfect cleanliness, including 
pure air. ;

A GROUP OF HYBRID DENDROBIUMS. 
DENDROBIUMS are among the gayest of winter and spring flowering plants, 
and as the hybrids now occupy such a prominent place in collections we 
have much pleasure in reproducing a photograph sent to us some time ago 
by Mr. H. J. Chapman, then gardener to R. I. Measures, Esq., Cambridge 
Lodge, Camberwell, and representing flowers from Mr. Measures’ 
collection. 
D. X ELListI vAR. WIGANIANUM, the upper central flower (fig. 22), is 
a hybrid raised in the collection of Sir F. Wigan, Bart., Clare Lawn, East 
Sheen, from D. Hildebrandii @ and D. nobile 3, and thus is the reverse 
cross of the original D. x Ellisii, which flowered just previously in the 
collection of W. S. Ellis, Esq., of Dorking. It was exhibited at the 
meeting of the R.H.S.on February 12th, 1901, under the name of D. 
x Wiganianum, and received an Award of Merit. The sepals and petals 
are very pale, and the lip prettily flushed with rose-pink round the maroon 
coloured disc. It is a floriferous and very beautiful hybrid. 
D. X S1ByL, the flower on the left (fig. 23), was raised in the collection 
of Norman C. Cookson, Esq., Oakwood, Wylam-on-Tyne, from D. 
Linawianum ¢ and D. bigibbum ¢, and received an Award of Merit from 
the R.H.S. in March 1893, and a First-class Certificate a year later. The 
flowers are of a pleasing shade of rose-purple, with a pale disc to the lip, 
and a pair of small orange-coloured spots at the base. The petals and lip 
are prettily undulate, but it is curious how completely the shape of the 
pollen parent has been obliterated. | 
D. xX Wicaniz, the upper flower on the right (fig. 24), was also 
raised in the collection of Sir Frederick "Wigan, from D. nobile ? 
and D. signatum 3, and flowered for the first time in March, 1896. In the 
following month it also flowered with Messrs. James Veitch & Sons, and 
received an Award of Merit from the R.H.S. Seedlings were also raised in 
the collection of Sir Trevor Lawrence, Bart., and flowered about the 
same time. The flowers are of a pretty shade of light buff, with a pair of 
dark maroon blotches in the throat. It is dedicated to Lady Wigan.
