DIPLADENIA CRASSINODA. 
Judging from its appearance and habit, it 
is not a plant at all liKely to be stamped with 
the character of individual permanency, and 
therefore not so well adapted as many others 
from the same regions, for cultivating as speci- 
mens of extraordinary size. The present 
plant rather bears the characteristics of neat- 
ness and simple elegance, and is therefore 
likely to be most pleasing in the state of com- 
paratively small but well-grown plants; not 
but that it can possibly be grown to a larger 
size, but is not so well adapted for that man- 
ner of growth as many others are. 
The principal features to be observed in its 
cultivation are, to secure for it a well-drained 
and open compost, and to secure it against damp 
in the winter. The ordinary light composts of 
peat soil, and loam, which arc used for delicate 
green-house plants, is suitable for this; but it. 
requires to have it well drained, and not in 
pots of too large a size: in proportion as tin- 
size of the pots is increased, the necessity 
for drainage, not only at the bottom, hut also 
well intermixed with the soil, becomes in- 
creased in an equal ratio. The plants should 
have plenty of air, in the summer season, and 
may also have, during the growing season, 
a liberal supply of water; but in no 
ought they to be exposed to heavy beating 
rains ; and in winter, it is imperatively u 
sary that all sources of dampness should he 
cut off. A slight degree of shading during 
intense sun-light, in summer, has been found 
to be beneficial. 
DIPLADENIA CRASSINODA. 
KNOB-JOINTED DIPLADENIA. 
This plant has recently been flowered for 
the first time in England, at Wallington Lodge, 
near Carshalton, in Surrey, the seat of R. G. 
Loraine, Esq. It is a native of Brazil, where 
it was discovered by Mr. Gardner ; and by 
that gentleman dried specimens were brought 
to this country under the name of Echites 
crassinoda. Subsequently, living plants were 
obtained by Mr. Low of Clapton, from Mr. 
Makoy of Liege, under the name of Echites 
Carassa, under which latter name it has be- 
come pretty generally known. Now that it 
has flowered, an opportunity has been presented 
of identifying it with the E. crassinoda of 
Mr. Gardner. This plant, together with the 
plants known as E. splendens, E. atropur- 
purea, and others, have been constructed into 
a new genus by Alphonse De Candolle, to 
which the name Dipladenia (from diplos, double, 
and aden, a gland) has been applied; this name 
has been given in allusion to the glandular 
appendages to the stem, situated at the base 
of each pair of leaves. The flowers are rose- 
coloured. 
The plant, as will be seen by the figure, is a 
climbing shrub; it has, too, just that perma- 
nency of habit which renders it particularly 
desirable in cultivation. It is evergreen, grow- 
ing at a moderate rate, and therefore capable 
of being grown into a large, permanent, speci- 
men plant ; and from the circumstance of its 
having bloomed in a very young state, there 
is presumptive evidence, that under proper 
management, it would be found to be liberal 
in the production of flowers. A stove is re- 
quired, but beyond this, there can be said to- 
be no difficulty in the way of success in :'ts 
cultivation. The plant, together with all its 
neighbouring species, grows freely enough in 
a compost of loam and peat, which should, as 
in all cases of plant culture, be used in a 
rough state, and with pots well drained ; thes3
