Generic Character. — Calyx five-toothed, deciduous ; lohes folia- linear. Stigma two-parted. Capsule dehiscing at the dissepiment 
ceous. Corolla with a longish tube, and a five-lohed expanded limb, from the apex. Wings of seed jagged. (jQ, Don.) 
which is imbricate in aestivation. Stamens almost inclosed ; anthers

Engravings. — Sweet’s Brit. Flow. Gard., 1. 145 ; Bot. Mag., t. 3946 ;

Specific Character. — Leaves elliptical, acuminate, many-nerved, 
glabrous above, hairy on the nerves beneath. Sepals linear, some- 
what obtuse. Tube of the corolla tadce as long as the limb, which is 
without tubercles. 
Description, &c. — This very ornamental plant is said to form in its native country a tree from sixteen 
to twenty feet high ; but in England, even when planted in the free ground of a conservatory, it does not exceed 
the height of nine feet. The flowers are not only exceedingly beautiful, and most delightfully fragrant, but they 
are very valuable from being produced in the winter season, when so few ornamental plants are in flower. The 
species is a native of Nepal, growing on hills in exposed situations, and flowering nearly all the year. It was 
introduced in 1823, but till lately it was found difficult to cultivate it, as it was generally grown in a stove, the 
atmosphere of which was too hot and close for it, while a common greenhouse was found too cold and damp. 
A medium has now been found, by growing the plant in a conservatory which is heated so as to preserve a regular 
temperature during the autumn and winter, and admitting air whenever it could be done without chilling the 
house. The soil in which it grows should be a mixture of loam and leaf-mould, and no “ other peculiar 
management is required except daily syringing during its growth, to destroy the red spider, to whose attacks it is 
extremely liable.” 
OTHER SPECIES OF LUCULIA. 
LUCULIA PINCIANA HooTc. 
This is a most splendid plant, closely resembling L. gratissima, excepting in the leaves, which are somewhat 
broader; shorter, and more closely veined, and in the flowers, which are white, and each furnished with five pairs 
of prominent tubercles or nectaries, which are very conspicuous on the limb of the corolla. The flowers form 
a large cyme, sometimes a foot or more in diameter. When they first expand they are of a pure white, but they 
soon change to a rich cream-colour, slightly tinged with pink. The outside of the flower is somewhat more deeply 
tinged, and the tube is a deep rose-colour. The flowers, like those of L. gratissima, have a most delicious 
fragrance. The species is a native of Nepal, whence it was introduced in 1844.
