Generic Character. — Calyx five-cleft, with one or 
two little glands on the interior on each side at the 
base of the segments ; glands sometimes ligulate, some- 
times scaly. Corolla salver-shaped, or with the tube 
cylindrical at the base, and funnel-shaped above, 
hispid about the origin of the stamens ; throat ex- 
appendiculate ; lobes twisted to the left in aestiva- 
tion. Anthers nearly sessile, inserted in the upper 
part of the tube, at the middle or below the middle, 
where the tube widens, sagittate, adhering to the 
middle of the stigma, acuminate at the apex, or ending 
in an acute membrane. Glands of the nectary 
two, alternating with the ovaries, obtuse, single by 
reason of two being for the most part joined evenly 
together. Ovaries two, sometimes longer than the nec- 
tary. Style one. Stigma globular, surrounded beneath 
with a reflexed, umbrella-shaped membrane. Follicles 
and seeds as in Echites. 
SPECiFrc Character.— Plant a climbing evergreen 
shrub. Stem branching and nodose. Leaves lanceo- 
late, acute, or sub-acuminate, coriaceous, and shining 
on both sides. Racemes axillary and compressed, 
usually six-flowering, elongating. Calyx lobes lanceo- 
late, acuminate, with the cylindrical part of the tube 
a little shorter, and the pedicels two or three times 
shorter. Corolla tube campanulate below the middle, 
lobes obovately orbicular. 
Synonymes. — Echites crassinoda, E. carassa. 
The splendour displayed in the rich and delicate hues which beautify the 
blossoms of this plant, must induce every one to regard it amongst the most 
magnificent things disclosed during the season of 1844. Specimens have been in 
the possession of several of the London nurserymen for two or three years, but 
none have yet produced flowers, with the solitary exception of a specimen procured 
from Mr. Low, of Clapton, which yielded to the attentive and skilful treatment 
practised in the excellent collection of R. G. Loraine, Esq., of "Wellington Lodge, 
to whom we are indebted for our figure, and whose courtesy and attention, on 
several occasions, we avail ourselves of the opportunity here afforded to 
acknowledge. 
This species is one of twenty which have been separated by M. Alphonse 
De Candolle from the vast number congregated under the name of Echites, and 
formed into a new genus, to which he has assigned the name Dipladenia, on 
account of each bearing a couple of glands at the base of the seed-vessel. 
Amongst these species we find the E. airopurpurea and E. splendens, (figured in 
previous volumes of this Magazine,) the latter of which bears a remarkable 
resemblance, in the prevailing hue and character of its blossoms, to the present 
species ; but they are much larger, paler coloured, and destitute of the fine orange 
throat, which adds so much to the beauty of D. crassinoda.
