are large, whitish, and have their lip mottled and striped with dark brown. It grows finely on a 
block of wood, suspended from the roof of the house. 
Va'nda vjola'cea. A most lovely species, lately flowered by Messrs. Loddiges. It is of a 
vigorous habitude, and the flowers are borne numerously on strong racemes. The sepals and 
petals are white, slightly tinted with violet, and the lip is richly striped with a violaceous purple. 
It is among the finest of the group. 
"YYola arbo'rea. The term " Tree Violet " has been applied to an interesting kind, which 
has fine deep blue, double, and fragrant flowers, and may, by treating it similarly to the 
Mignonette, when it is wanted to form a shrub, be made into a beautiful dwarf woody plant, with 
a stem a foot or more in height, and the leaves and flowers drooping gracefully from the summit. 
To bring it to this state, it is only necessary to remove the flowers and side shoots for the first 
year or two, and then to let it take its own course.. We have not, for a long time, met with a 
more pleasing and delightful object. 
ZfcHYA Mo'lly. The handsomest of all the Zichyas in regard to the size of its flowers, and 
readily known from Z. coccinea or tricolor by the much greater size of its foliageand blossoms, 
and the smoothness and comparative softness of the former. Its flowers are, however, rather 
paler than those of the species just referred to, and more like the blooms of Kennedy a Stirlingii. 
It is blossoming in good condition at the gardens of the Horticultural Society, Chiswick, where 
it is trained to a low trellis, and kept in a pot in the large conservatory. 
Zi'ciiya villoma. Principally separated from Z. coccinea by the downiness of its leaves. In 
other respects, it constitutes an equally beautiful climber, and its flowers are of the usual red and 
yellowish hue. Messrs. Henderson, of Pine-apple Place, have flowered it in their greenhouse, 
having obtained it from Australia.

The beauty of the flower-borders at this season will have, in some measure, diminished the 
necessity for rendering the plant-houses as gay as they should be during the months of March and 
April, and the flowering period of many in-door* exotics will also now be past. Yet the houses 
can still be made very attractive by the introduction of flowering annuals, Pelargoniums, Calceo- 
larias, Gloxinias, Treviranias, &c. ; and in the absence of flowers from the common stock, more 
attention should be bestowed on the growth of their new shoots, and their general health. 
Some remarks will be found in a previous, page on the beneficial effects of removing withered 
blossoms, ere the seed gets time to develop itself ; and these are peculiarly applicable to plants 
in pots, which are necessarily more injured by extra exhaustion in consequence of their roots 
being so confined. A vigilant superintendence should therefore be exercised in this particular ; 
and likewise in regard to the shortening of young and weakly shoots, treated of in a former 
Number. The directions concerning the latter do not, however, refer so much to the annual and 
proper growth which plants make at this time, but rather to the adventitious developments of 
prior and subsequent periods. Still, where new shoots are too long, or too feeble, or not taking 
the right direction, it is better to reduce them now than let them expend their strength to 
no purpose. 
Watering, during this and the following months, is a work requiring to be very constantly 
performed. While we speak thus, we do not mean that each specimen should be watered 
regularly, at certain stated hours, but that the cultivator must be always on the watch to apply it 
where necessary. Some kinds of shrubs, such as Rhododendrons, Camellias, and Hydrangeas, 
require to be almost deluged with water at the present time ; and, provided the pots or soil in 
which they grow be properly drained, can hardly have too much. For others, as Heaths, more 
caution is requisite. The best general criterion, apart from the actual examination of each 
specimen, — which, after all, is the only safe and correct mode of proceeding, — is the amount of 
surface which the leaves of a growing plant presents to the atmosphere. Large and broad-leaved 
species demand large supplies of moisture s on account of their great evaporating surface ; while
