larcre. and the plant is therefore more effective' for planting on 
rock-work, for which it is very suitable. The flowers vary 
from lilac to purple, and a corresponding change may be 
(seen on the palate of the lower lip, which has a white spot 
varying to orange. The slender stems trail about on the 
ledo-es of the rookery, and flowers are produced over a com 
jsiderable period. I have compared it to the native species 
for the simple reason, that it belongs to the Ivy-leaved section) 
of Linaria. It is of very easy propagation by division of the 
{crowns, by taking cuttings or by seeds. 
Veronica incana. 
In some respects this may be compared to some of the 
forms of the British Y. spicata, but the stems are stouter, 
more decideidly erect, and the leaves are more or less of a 
decided silvery-grey hue. There is another closely allied 
plant, which is known in gardens under the name of V. neg- 
lecta, which is also both useful and effective, but I prefer the 
more typical Y. incana, on account of the silvery hue of the 
leaves. Indeed, so decided is this in most cases that many 
gardeners have employed it in summer-bedding designs on 
account of the distinct hue of the foliage. The flowers are of 
a rich blue, and produced in terminal spikes, so that the plant 
is a conspicuous and notable object on the rockery, whether 
in bloom or not. Propagation can easily be effected by 
division,, unless a large number of plants are required, when 
seeds may he employed. 
Cyananthus lobatus. 
For a cool, shady position in a pocket filled with peat, this 
makes an interesting plant, even although it does not produce 
any great profusion of flowers at any season of the year. The 
slender stem terminates in a single large fivedobed clear blue 
flower; the leaves themselves are lozenge-shaped, and are 
deeply toothed, recalling very much what occurs in Calceo¬ 
laria violacea on a larger 1 scale. The corolla is bearded in the 
throat, with white hairs, suggesting that it might belong to 
the Gentian family, where we find something similar, but it 
really belongs to the Bellflower family. Propagation can be 
accomplished by means of cuttings of the barren •- loots 
durum the earlier or middle portion of summer. 
Alchemilla. 
Cypripedium montanum. 
Several very beautiful Slipperworts are now in cultivation, 
and most, of them are so exquisitely pretty that we are sur¬ 
prised lovers of hardy plants do not adopt, them more 
1 generally. It is true that out of doors they require rather 
special treatment, but more particularly the selection of a 
proper site for their successful cultivation.. 10 puncq a 
points to be observed are .to select a, situation that v i e 
shaded from the mid-day sun, though at the same time the 
plants will be fully exposed to light and not overhung y 
In the wild state they only grow in situations that are 
shaded by trees or bushes in the vicinity, or where there is 
plenty of moisture in the ground. With tire object, of seem¬ 
ing the latter a bed may be made up, consisting c pea oi 
leaf mould ; indeed, the latter may constitute a large portion 
of the staple of the soil. The leaf mould or peat makes a 
soil that is more retentive of moisture than the ordinary 
garden soil, besides which we think such soils would contain 
more of the natural element that conduces, to tie we aic 
these terrestrial Orchids. , 
The species, above named is a native of Oregon, tram 
whence it was introduced in 1883. Now, this coun.iy 
be dry at certain seasons of the year, but as the a *' 
other periods is decidedly heavy, we mav expect ia it 
situations which will retain moisture in a senn-bog condition 
would be fairly numerous, or that the plants .grow w leic 
leaf mould or other decaying vegetation is plentiful, thereby 
constituting a moist medium for the roots'. About t iu mu 
this plant would come into bloom in Britain, moisture m the 
roil is still fairly plentiful in the average of years, ibis may 
be accentuated, however, by making up a compost as above 
described. 
There are cultivators, however, who take delight in grow¬ 
ing this class of plants in pots, so that they can. transfer 
them to a cool greenhouse, unless, indeed, they have properly 
constructed houses for the growth and flowering of various 
alpine and other hardy plants, which may bloom early and 
only require the protection of glass to save them from the 
inclemencies of our climate, which may be foreign to them. 
We must remember also ithaib a great many peat and bog- 
loving plants find the needful germs in such a soil that would 
not be present in ordinary garden soil. This, we believe, 
is one of the explanations why such plants are more easily 
grown, flowered, and preserved in pots or pan® stood in a cold 
frame. Cultivators who love this, class of plants naturally 
usie leaf soil or peat, and usually plunge the pots in ashes, so 
that all the conditions necessary for their welfare' are thereby

_ AND WHITE. 
given them. Even should they be placed in a greenhouse 
they are always under the eye, and a careful plantsman will 
always supply them with water when they get dry. 
The species we illustrate on this occasion is of much more 
slender growth than C. speotabile, which is usually regarded 
as the queen of this section. It varies from 6 in. to 12 in. 
in height, and the stems are well furnished with short, ovate, 
and lanceolate plaited leaves. Each of these stems carries 
one or two flowers,. The crowns must have been rather 
numerous in the case of the piece which we figure, and there¬ 
fore more crowded than usual, but the small plant of eight or 
nine stems made a very pretty object about the end of May 
and beginning of June, when we had it photo,graphed in the 
collection of Mr. G. Reuthe, Hardy Plant Nursery, Keston, 
Kent. The sepals and twisted petals are brownish-purple, 
and the white lip striped inside with red.
