x Kewensis.—In the Bulletin for 1893, p. 342, the Herd 
of thè first part of this important compilation was announé nd 
particulars given of its history, scope, and probable date of eotililotoi: 
Happily nothing has occurred to impede the progress of the work, 
and the Yast part is in the hands of botanists, within the period 
originally estimated for passing it through the press. Sir Joseph 
Hooker and Mr. Daydon Jackson, the principal crates are to be 
heartily eotigratalated on the accomplishment of this great and arduous 
undertaking, in which the resources of Kew have P-ren so important a 
part. As already explained, this index covers the period from the 
establishment of binominal nomenclature by Linnæus in 1753 down to 
the end of 1885. This leaves ten years, and ten very active years, of 
botanical work still unindexed; but it is rP rM to know that a 
supplement covering this dec ade is in a forward state of preparation. 
» Be Durand, of the Royal Herbarium, Brussels, began this supplement 
e years a o, and even offered the first five years of it to the editors 
of t the Index j hein for i -— aticn in that work, but the offer was 
declined because acceptance would have delayed publication and inter- 
fered with the original plan. Bie were — however, to encourage 
and assist M. Durand, and arrangements are in progress for publishing 
the supplement uniformly with the Index det Mr. Daydon Jackson 
is now actively assisting M. Durand, ans is hoped that they will be 
able to publish during the course of n ver 
K stem of Greenhouse Construction—The periodical recon- 
struction of the houses in which plants are grown under glass is a 
to which it is necessarily exposed. To obviate this difficulty iron has 
for some years been freely used in the construction of Sreenhousee, at 
es which can 
be easily replaced at any time, if they become decay ed, rest conveniently 
on the arms of the inverted T. 
This method of stint ation has proved perfectly successful, and the 
Conservatory, No. IV., as well as the Temperate Fern House, No, IH., 
are good examples of the method. 
The merits of the system have not pueda the attention of the 
horticulturists of other countries. The Royal Board of Works and 
Buildings, Munich, and the Board of Commissioners of the Zoological 
Gardens erdam, have severally applied for detailed working 
drawings of the mode of construction employed in the Kew houses, 
And these have been furnished accordingly by the First Commissioner 
of Her Majesty’s Works and Public Buildings. 
Rosa wichuraiana.—This very distinct and ornamental rose, which has 
lately ae the subject of much praise in the gar ardening journals, has 
recently been figured in the Botanical Magazine (plate, 7421), tinder 
the name of R. Lucie, with which species it was formerly associated, 
when only known from ‘dried specimens. The reduction has been the 
cause of some questions being addressed to Kew, and it may, therefore, 
be useful to give the histoty of the name wichuraiana. It was
