: Thunbe'rgia chry'sops. Perhaps there has not been a finer plant introduced for some years 
lan the present handsome stove species. It far surpasses all other members of the genus yet 
iaown in England. The flowers are produced singly from the axils of the leaves, and have a 
ng tube, very narrow at the base, but swelling towards the throat, and expanding into a large 
>reading limb. The interior of the tube is clear yellow, and as the throat is about half an inch 
ide it is readily seen. This is surrounded with a ring of a bluish colour, like the hue of the 
ower of T. Hawtayneana, which is again bordered by a rich violet colour, occupying the chief 
ortion of the spreading segments. Before the flowers expand, the buds are rather pointed, and 
: most black, glistening brightly as though washed with gum. The leaves are heart-shaped, on 
i ng foot-stalks, and are irregular at the margins, like those of T. alata. A plant from the Kew 
ardens was exhibited in Regent-street, in the beginning of June. It appears likely to be an 
mndant flowering species, and will form a delightful companion to the white, buff, and orange 
owers of T. leucanthe , T. alata , and T. aurantiaca.

OPERATIONS FOR JULY. 
In this month, as, indeed, in all others, much of the work to be performed must be regulated 
y the state of the weather. Everything in the outdoor department must be so provided for, that 
sither extreme wetness nor drought may entirely frustrate the cultivator’s intentions, or wholly 
isappoint his hopes. If the tender plants, transferred from the greenhouses and frames to the 
irterre, in May and the early part of the last month, have been planted with an eye to this 
iriable and uncertain condition, so as to secure a medium state that will readily admit of 
oprovement should either extreme prevail, little will be required now. 
To correct aridity and intense sunshine, or a continuance of cold and cloudy days with a super” 
oundant fall of rain, it may, however, be necessary to employ some ameliorating means. To 
try the former, shades may be interposed in stoves and greenhouses, where the plants are 
>nder, and water applied where more moisture is needful ; to avoid the latter, let every facility 
! s employed to promote the quick passage of water from the immediate vicinity of the roots, and 
le branches should be kept from becoming too crowded. 
Where shade is deemed requisite to prevent the injury likely to result from a direct exposure 
» the rays of the sun, it must be borne in mind that light is yet necessary to the maintenance of 
igorous health and beauty. Plants will require a diffused light to grow and increase with 
adiminished strength, even where its direct influence is insupportable. Shade, therefore, must 
ever be interpreted to mean darkness, and it must only be applied during that part of the day 
1 hen the rays of the sun are most intense and injurious. In the morning, when the plant is 
^freshed by the partial suspension of its digestive powers, and its parts full of moisture, absorbed 
uring the night, a warm sun will be less injurious than in the after part of the day, if the houses 
! re properly ventilated. But towards the evening of a clear day, unless the quantity of moisture 
hich a plant is able to obtain from the soil is equivalent to the expenditure, a warm sun will 
luse it to flag, or droop its foliage, and the extremities of the growing parts. Therefore the 
mdition of the plant, and the peculiarities of the weather, will each form a subject equally 
nportant, and necessary to be regarded conjointly in the application of shade. Houses built 
ith a span roof are superior on account of the advantages which they possess for the application 
f shade. The eastern side may be covered in the morning, and the western in the afternoon, 
ius admitting sufficient light through the one side, and preventing the hurtful effects of immediate 
anshine, by having a slight screen on the other. 
In every place where plants are grown in pots, some degree of shelter will be indispensable, 
( hether they are placed in the greenhouse or the reserve garden. The destructive effects of the 
^ irect rays of the sun falling on plants, is as much, or, perhaps, more owing to the pot or tub in 
hich the plant is grown becoming too much heated ; and, consequently, the soil immediately 
grounding the major part of the most active roots is deprived of a sufficiency of moisture, 
lants grown in the border of a conservatory, or plunged amongst ashes in their pots, or their
