Pterostigma grandiflorum. This is one of the new introduc¬ 
tions by the Horticultural Society. It was received from Mr. 
Fortune, who described it as a blue flowered herbaceous plant, 
growing on hill sides and near streams in the island of Hong- 
Kong; it is new to our gardens. In its wild state this plant does 
not appear to grow more than a foot or eighteen inches high,, but 
in gardens it has become more than three feet high ; the conse¬ 
quence of which is that its natural beauty has been greatly im¬ 
paired. It is a perennial, covered all over with slender spreading 
hairs. The stems are round, the leaves are opposite, ovate, ere- 
nated, very much marked with sunken veins, and deep green. 
The flowers, which are nearly as large as those of a digitalis, and 
of the deep colour of Gloxinia violacea, grow singly in the axils 
of the leaves, than which they are considerably shorter. Their 
calyx appears to consist of seven narrow green leaves, imbricated 
at their base, hut the number varies to eight. They form a com¬ 
plete broken whorl, and may be understood to consist in part of 
bracts, which stand close to the true sepals and become blended 
with them; of these, the three exterior are both broader and 
longer than the others. The corolla is tubular, two lipped, with 
the upper lip broad, ovate, blunt, and notched, while the lower 
is composed of three smaller divisions placed nearly on the same 
plane ; in this respect the flowers vary: some of the specimens 
having four lobes in the lower lip. The usual number of stamens 
is four, of which two are perfect and next the upper lip, and two 
stunted, of the same length but more slender, and belonging to 
the lower lip ; when an additional lobe appears in the lower lip 
of the corolla it is accompanied by an additional sterile stamen. 
The perfect anthers are constructed in an unusual manner; at the 
end of the filament is a large globular green gland, which even¬ 
tually shrinks up ; upon this green gland are planted two lobes 
of unequal length, bursting longitudinally. The style and stigma 
too are of a singular form; the former gradually widening and 
flattening upwards till it ends in a thin broad plate, which curves 
forward and forms a stigma on its anterior edge.— Bot. Reg.
