DIPLADENIA NOBILIS. (NoWe DipladenO 
Class, Pentandria, Order, Monogynia. Nat. Order, Apocynace^ (Dogbanes, Veg. King. 
Generic Character —CaZ?/^ five-cleft, with one or two 
little glands on the interior on each side at the base of the 
segments ; glands sometimes ligulate, sometimes scaly. 
Corolla salver-shaped, or w^ith 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 {Estivation. 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 nectary. Style one. Stigma globular, 
surrounded beneath with a reflexed, umbrella-shaped mem- 
brane. Follicles and seeds as in Echites. 
Specific Character. — Corm roundish, tuberous. Stem 
and every part quite smooth. Leaves on very short stalks, 
oblong, acute, rounded at the base, with numerous promi- 
nent curved veins. Flowers in terminal one-sided racemes, 
large, distinct, smooth. Sepals very narrow and acute, 
much shorter than the pedicel. Corolla between tubular 
and campanulate, very narrow at the base (two inches 
long), with roundish-ovate (or acuminate) lobes (white on 
the border, pink in the tube and throat, greenish at the 
base). — Lindley, 
1. Rose-coloured variety.— Flowers uniformly pink, with 
a large finely-expanded limb ; lobes of the corolla acumi- 
nated ; orifice of the tube wide, base very contracted. 
2. Pale variety — Expanded limb of the flowers nearly 
white; lobes roundish-ovate, orifice of the tube more con- 
tracted than in the dark variety, of a deep crimson purple, 
as is also the greater part of the tube ; base less contracted 
than in the dark variety, and of a waxy yellowish appear- 
ance.

and was named by Professor 
Catherine's to M. Verschaffelt, 
in June, 1847. 
This fine species of Dipladenia is a native of Brazil, 
Morren, who informs us that the corms were sent from St. 
who obtained a first prize for it at the Exhibition at Ghent, 
The Professor notices two varieties, with 
flowers very dissimilar in appearance, although 
perhaps neither of them scarcely equal to 
those of D. splendens and crassinoda ; they 
are, however, first-rate additions to this very 
beautiful genus. Both of these varieties we 
have figured in the accompanying plate. 
Our drawing of the dark variety was 
made in the Nursery of Mr. Glendinning, 
Turnham Green, in whose stove it bloomed 
during the month of October, 1847. The 
plant was received, about two years ago, by 
that gentleman from M. Miellez, of Lille, 
without any particulars respecting its history, 
except that it was first imported about 
three years since into Belgium, from South 
America, by one of the Belgian collectors. 
Mr. Glendinning is of opinion that the two 
varieties are not really distinct, or the colours 
permanent, but that they become dark or 
light, according to the local circumstances in 
which they are placed, a change not uncom- 
mon in the members of this genus. 
Our figure of the pale kind was made at 
Messrs. Rollisson's, Tooting, during the same 
month mentioned above. In both places the 
plants, when in bloom, were fine objects. 
The species is a stove cUmber, and both of its varieties thrive well in a mixture of 
equal parts light rich loam, heath mould, and very coarse sand. When in bloom, it is
