THE ORCHID REVIEW. 69 
Dendrobrium x splendidissimum, which next appeared, is one of the 
handsomest hybrid Dendrobiums yet raised. It was obtained in the Royal 
Exotic Nursery, by crossing D. aureum with the pollen of D. nobile. Thus 
it has the same parentage as D. x Ainsworthii, of which it may be con- 
sidered as a very fine variety, with all the segments tipped with rosy mauve 
instead of being pure white. .It probably owes its character to the finest _ 
forms of each species having been selected for parents. It was at first 
thought that D. superbum instead of D. nobile might have been one parent, 
but the idea has since been given up. 
Another Dendrobium immediately followed, and was described as D. x 
micans. It was derived from D. Wardianum (the old Assam form) ? and D. 
lituiflorum, two species not hitherto used for hybridisation purposes. A 
single flower was produced in February, 1879, when the plant was only 
three years old. Mr. Seden was the raiser. 
Cypripedium x vernixium was the first hybrid from C. Argus, the pollen 
having been derived from C. villosum. It presents a combination of the 
characters of the parent species, but those of the pollen parent preponde- 
rate. It was raised by Mr. Seden. 
Selenipedium x Ainsworthii, another secondary hybrid, was raised by 
Mr. Mitchell, gardener to Dr. Ainsworth, Cliff Point, Broughton, Man- 
chester, from S. Roezlii crossed with the pollen of S. x Sedeni. Like most 
of its allies, it is a vigorous and floriferous hybrid. 
- Lelig x Philbrickiana was next described. It was the first hybrid from 
Cattleya Aclandiz, the pollen being derived from Lelia x elegans. It isa 
handsome hybrid. It was raised by Mr. Seden, and was dedicated to F. A. 
Philbrick, Esq., Q.C., of Oldfield, Bickley. 
Cypripedium x porphyrospilum, described = Reichenbach, was the last 
hybrid of the year. It was not a distinct cross, however, as it came from 
the same seed capsule as C. x pycnopterum, of which it can at most be 
considered as a variety. C. venustum ? and C. Lowii f were the parents. 
In 1880 another genus was added to the list, when the handsome Masde- 
vallia x Chelsoni flowered for the first time. It was the first seedling 
Masdevallia raised in Europe, and was obtained by Mr. Seden, by crossing 
M. amabilis with the pollen of M. Veitchiana. The flowers exhibit a charm- 
ing combination of orange and crimson, and, being studded with the irides- 
cent violet hairs of the pollen parent, the colour varies according to the 
direction from which the light falls. 
Chysis x Sedeni, the second hybrid in the genus, which flowered 
immediately afterwards, was also raised in Messrs. Veitch’s establishment. 
ts parents were C. Limminghii and C. bractescens, the latter being the 
Pollen parent. It is said to have the habit of the mother plant, _— 
flowers more nearly resembling those of C. bractescens. 
The remaining hybrids described in 1880, with the single exception of
