in, and a sharp watch must be kept for any appearance of these insects.. 
Should any be present, fumigate with tobacco powder, having removed 
previously any plants which are in flower, or just bursting their buds. 
Cymbidiums should now be rooting well, and may receive liquid cow 
manure once a week. Since these Orchids are such vigorous rooting 
subjects, and owing to their disliking frequent repotting, I am convinced 
that some stimulant is necessary to encourage them, and liquid manure 
has been found eminently satisfactory. An application of this should be,. 
however, immediately followed by a dose of pure rain water. 
CYPRIPEDIUM FRANKEANUM. 
WHEN the natural hybrid Paphiopedilum Frankeanum was described five 
years ago (O.K., xvi. p. 29) the history of its two parents, P. Curtisii and P. 
tonsum, was given, showing that the latter originally appeared quite 
accidentally in an importation of the former, which it resembled so closely 
in the foliage as not to have been recognised until it bloomed. We could 
not then find a record that the cross between the two had been made in 
gardens, and remarked ‘“‘ we hope it will now be attempted.” At the 
Brussels Botanic Garden a few days ago M. Gentil showed us a seedling in 
bloom that had been obtained from C. Curtisii crossed with the pollen of 
C. tonsum, and also gave us a flower, which agrees well with the natural 
hybrid sent by M. Theodore Franke. The leaves bear a general resemb-. 
lance to the original P, Curtisii, whose characters on the whole predominate 
in the flower, though the petals are not so drooping, the blackish spots few 
in number and not regularly arranged, and the hairs on the upper margin. 
rather longer and much less numerous, characters also noted in the wild 
hybrid. The dorsal sepal is shortly acuminate, and closely striped with 
purple and green, and the lip has rather more of the tonsum character. It 
is very interesting to have the origin of the plant proved experimentally.

ORCHIDS AT KEW. 
THE Orchid Houses at Kew are looking very gay just at present, there 
being quite a good display of flowers, both in the warm and cool divisions. 
A number of botanical species may be seen in bloom, a few of the most 
interesting being as follows :— 
Promenza xanthina is a charming little Cool house subject, and grows- 
best when suspended from the roof-glass in pans. The flowers are bright 
citron-yellow, spotted with red on the side lobes of the lip. 
Kefersteinia graminca is a very rare plant, allied to the preceding. It 
has no pseudobulbs, and the leaves are five to nine inches long, and the 
Scapes about five inches high, the sepals and petals being light yellowish.
