form for those shrubby species which are capable of being trained with an erect 
stem, to the production of a drooping, brandling head, is to have a strong perpen- 
dicular rod of iron, surmounted by a circular convex frame of weaker wire, so as 
to resemble a parasol in figure. Others will be better exhibited by a frame in the 
shape of a spirit-flask or a balloon. An infinity of types might be mentioned, or 
illustrated by engravings, but every needful diversity can be procured at any wire 
manufactory in the vicinity of the metropolis, and, we presume, at most other large 
towns. One essential point in their structure should not be forgotten, which is 
that the summits be always so recurved that the upper shoots of the plants grown 
upon them may not protrude far above the trellis, but rather depend gracefully on 
all sides. Perhaps, in a future number, we may furnish a list of such plants as are 
particularly suitable for this mode of growth, and add some apposite suggestions on 
the treatment they should receive previously to being thus exposed : on the present 
occasion, our space precludes further detail.

NEW AND RARE PLANTS, FIGURED IN THE LEADING BOTANICAL PERIODICALS FOB 
JULY. 
CLASS I.— PLANTS WITH TWO COTYLEDONS (DICOTYLEDONEiE). 
THE BEAN TRIBE {Leguminbsce). 
Edwardsia macnabiana. Mr. Macnab's Edwardsia. Strongly resembling 
E. grandijlora in general appearance and habit, it is highly probable that ' this 
plant is merely a seedling variety ; but, says Dr. Graham, "it is instantly distin- 
guishable from the ordinary form of that species, by its nearly equal petals, by the 
wide separation of the petals of the keel, and by its flowering when in full leaf." 
No other distinctive particulars are enumerated, nor is the source whence it 
was obtained known. Plaving been cultivated for many years in the Edinburgh 
Botanic Garden, it is found to be somewhat more hardy than E. grandijlora ; and 
when trained against a protective wall, forms a really handsome shrub. The 
profusion of bright yellow flowers is very striking; but, like the species above 
referred to, it appears deficient in foliage. Bot. Mag. 3735. 
THE ASCLEPIAS TRIBE (Asclepiadacea:). 
Ceropegia vinc^efolia. Periwinkle-leaved Ceropegia. Of this very curious 
genus, the present plant constitutes a new and slightly interesting species. 
Considered as a stove ornament, it presents few attractions ; but there is a degree of 
gracefulness in its general disposition and flowers, the latter being, moreover, 
prettily spotted, which will render it welcome to the admirers of novelty. It has 
twining stems, and opposite, ovate leaves, from the axils of which the flowers
