Class, Didynamia. Order, Angiospermia.- Nat, Order i, Scrophulariace^e .(Fig-worts, Veg. Kingd.) 
Generic Character. — Calyx membranous, tubular, ten- 
ribbed, five-toothed. Corolla salver-shaped, resupinate from 
the contortion of the peduncle ; tube fifteen-nerved, ventri- 
cose at top ; limb oblique, five-lobed. Stamens four, didy- 
namous, without any rudiment of a fifth. Anthers of the 
upper filaments reniform ; of the lower ones parallel with 
the filaments, having the upper cell the smallest, and some- 
times abortive. Ovary surrounded at the base by a large, 
cup-shaped, fleshy disk. Stigma two-lobed, four-tubercled, 
with two excavations on the back for the reception of the 
upper anthers. Capsule oblong, two-celled, two-valved, 
many-seeded. Dissepiment contrary. Placentas two, fleshy. 
Seeds angular. 
Specific Character, — Plant ashrub. Stem erect, branched , 
glabrous (as is almost every part of the plant). Leaves some- 
times opposite, sometimes alternate. Peduncles axillary, 
solitary, single-flowered, in general shorter than the leaf. 
Calyx-tube ovato- cylindrical ; limb of five, erect, subulate 
segments, nearly equal in length with the tube. Corolla 
hypocrateriform ; tube long, slender, thrice the length of the 
calyx ; limb oblique, somewhat two-lipped, of five large, 
spreading, ovate acuminate segments, striated pale-lilac 
beneath, dark-purple above ; throat white. Stamens inserted 
in the faux, didynamous ; filaments short, ciliated, curved 
above. Anthers didymous. Ovary globose on a short small 
disc, two-celled. Ovules very numerous on a large central 
placenta in each cell ; style nearly as long as the tube of the 
corolla. Stigma two-lipped, four-lobed within the lips.

This new species of Browallia, although less striking in the colour of its flowers than 
the B. Jamesonii, which we figured at t. 7. in the present volume, is yet in beauty not 
far behind it. Altogether it must be considered a very fine kind, the flowers in point of 
size are larger than those of any other known species, the colours are a bright purple 
shaded with blue, and are very conspicuous. 
It is a native of Peru, where it was discovered by M. Purdie, growing on the 
Mountains of Tolima and Quindiu, in the year 1846, when it was introduced to the Royal 
Gardens at Kew, where it flowered in September, 1847. 
The specimen from which our drawing was prepared bloomed in the stove at the 
nursery of Mr. Glendinning, of Turnham Green, in August last. 
The plant requires only the ordinary treatment of other annual Browallias ; it however 
produces its flowers to greater perfection if favoured with either the heat of a stove or a 
warm part of the greenhouse.

MANDEVILLA SUAVEOLENS. (Sweet-scented Mandevilla.) 
Class, Pentandria. Order, Monogynia.- — Nat Order, Apocynacete. (Dog-banes, Veg. Kingd.)

base campanulate, five-lobed ; top two-pointed. 
Specific Character. — Plant an evergreen shrub. Stem 
twining. Branches slightly pilose, whilst young, but be- 
coming smooth as they advance in age. Leaves opposite,

cous beneath, smooth above. Stipules comb-like. Racemes

Lindl. in Bot. Reg., vol. xxvi.,t. 7. 
This fine white-flowering twiner was introduced from Buenos Ayres by H. J. H. Mandevilie, 
Esq., some years ago, and was beautifully figured by Dr. Lindley, in the “Botanical 
Register,” v. 26, t. 7. Although nine years have elapsed since its publication, the plant 
is hitherto very little known, and by no means cultivated to the extent that its merits 
deserve. 
Its twining habit and pendent snow-white flowers, emitting a most delicious fragrance, 
give the plant somewhat of the appearance of a Jasmine. It is a rapid grower, and
