Fancy Cactus Dahlia Mercury. 
This has long, slender florets twisted or 
whorled sideways, of a soft yellow, striped 
and mottled with crimson. These mark¬ 
ings determine that it is a fancy Cactus 
Dahlia. First-class certificate to Messrs. 
James Stredwick and Son, St. Leonards- 
on-Sea, by the London Dahlia Union at 
Regent's Park on September 12th. At 
the same time they had first-class cer¬ 
tificates for Cactus Dahlias C. E. Wil¬ 
kins and Rev. A. Bridge. These we have 
previously described.

the summer time, therefore the frame¬ 
work of this huge natural umbrella may 
be seen just above the leaves, the brown 
colour showing up the branches against 
the green leaves. 
If allowed to grow at its own free will 
it sometimes produces a branch of un¬ 
common vigour on one side in the same 
way as the Weeping Beech, but the Elm 
is much more easily controlled, however, 
than the latter, and if the cultivator de¬ 
sires his tree to be of a uniform weeping 
habit with the regularity of an umbrella 
the unusual strong branches may be

one can have blooms early or late accord¬ 
ing to the culture applied. This Hy¬ 
drangea may be also raised from seeds. 
As a shrub, it flowers profusely in 
August, given a good, light, and drained 
soil. In April it should be thinned out 
to the best growths.

A Great Work on Botany. 
What is probably the finest work on 
botany ever published has recently been 
issued from a Leipzig press to the order of 
the Brazilian Government. It consists of 
forty volumes, comprising 130 parts, with 
20,733 pages dealing with 40,000 species 
of flora found in Brazil. The work was 
begun in 1S19 by Martius, and has been 
built up by 65 authors. 
Sophrolaelia Gratrixae magnifica. 
The parentage of this, hybrid was S. 
grandiflora x L. tenebrosa. The sepals 
are bronzy brown, while the petals are 
lighter with a median dark band. The 
lip is crimson with a rose apex and the 
white tube is lined with purple. Award 
of Merit by the R.H.S. on September 
17th when shown by F. Monteith Ogil- 
vie, Esq., The Shrubbery, Oxford. 
The various species of Elm in cultiva¬ 
tion have given rise to a considerable 
number of varieties, and amongst them 
no less than ten weeping varieties have 
been recorded in cultivation. None of 
them are so popular, however, as the 
Weeping Scotch Elm, or Weeping Wych 
Elm. 
It is a very characteristic Elm, and that 
may account for its popularity. The 
leaves are much larger than in the ordin¬ 
ary' upright form of the Mountain Elm, 
and they assume a particular habit that is 
very characteristic, and may' be recog¬ 
nised at a distance. The branches assume 
an arching form naturally, and gradually' 
grow down towards the earth. From each 
side of the main branches short ones are 
given off, and each branch has two rows of 
leaves which spread horizontally', but dip 
a little below the branches. Even during 
pruned back in winter to give the tree 
shape. By' thus checking the strong 
branches and leaving the weaker ones to 
grow at their freedom the tree may be 
kept well balanced by a little attention 
annually after the leaves have dropped. 
The accompanying illustration shows a 
tree about 30 feet high, but much smaller 
specimens may be obtained. In the first 
instance they' may be had with stems of 
various lengths, and by pruning they can 
can be kept down to the original tier of 
drooping branches, and they may' be cur¬ 
tailed so as to fit the space where they 
have been planted. It is not well, how¬ 
ever, to prune too severely, otherwise it 
gives the tree a formal appearance. The 
pruning is rendered necessary, however, 
when the tree is planted in restricted 
areas, but a fine effect is produced if the 
tree is allowed to attain considerable size 
where the space will permit.
