THE ORCHID REVIEW. 39° 
Cypripedium x Marshallianum was derived from C. venustum pardinum 
and C. concolor, the latter being the pollen parent. It is a very distinct 
and charming little plant, in which the influence of the pollen parent pre- 
ponderates to a very marked degree. 
Hybrid Orchids were now decidedly on the increase, for at least ten 
flowered for the first time during 1876, and the work of three new operators 
came before the public, as will presently be seen. 
Cypripedium x cenanthum, the first secondary hybrid in the genus, was 
described early in the year. It was raised by Mr. Seden, by crossing 
C. x Harrisianum with the pollen of C. insigne Maulei, and thus establishes 
a record of another kind, being the first instance of a hybrid Orchid being 
successfully used as the seed-parent. The theory of the sterility of hybrids, 
if ever maintained with regard to plants, must have received a shock with 
the flowering of this plant. As in the case of Cattleya x fausta, an 
unusual amount of variability presented itself between the different plants 
obtained from this cross. It isa very brightly-coloured and attractive hybrid. 
Another. hybrid Dendrobium now appeared, being raised by Mr. Seden 
from D. moniliforme (D. japonicum) crossed with the pollen of D. aureum. 
It received the name of D. x endocharis, in allusion, we suppose, to the 
satisfaction with which the opening of its first flowers was regarded. Its 
chaste flowers are pure white, with a handsomely pencilled disc, and 
deliciously fragrant. ; 
The next hybrid was Selenipedium x stenophyllum, raised in the collec- 
tion of John C. Bowring, Esq., of Forest Farm, Windsor, who thus gave 
evidence of having turned his attention to hybrids. It was obtained by 
crossing S. Schlimii with the pollen of S. caricinum. 
Cypripedium x pycnopterum, the first hybrid from C. Lowii, was 
obtained by Mr. Seden from C. venustum crossed with the pollen of the 
species just named. It is a very distinct hybrid, in which the influence of 
the pollen parent greatly preponderates. 
Cypripedium x superciliare was obtained by crossing C. barbatum with 
the pollen of C. superbiens. The flowers are large and intermediate in 
character, though inclining to the light colour of the pollen parent. It was 
raised by Mr. Seden. 
Dendrobium x rhodostoma, which next appeared, was a decided novelty, 
being obtained by crossing the rare D. Huttonii with the pollen of D. san- 
guinolentum. It bears a considerable resemblance to the latter. Lt 16 2 
free grower and ver y floriferous. Mr. Seden was the raiser. : 
The next hybrid which flowered was the work of a new operator. It was 
raised in the collection of the late W. Leech, Esq., of Oakley, Fallowfield, 
Manchester, by Mr. William Swan, by crossing Cypripedium Dayanum with 
the pollen of C. barbatum, and was named C. x Swanianum, in honour of 
the raiser. It was the first seedling from C. Dayanum.
