Spec. Char., §c. Stem round, Leaves sessile, lanceolate, numerous, without dots. Peduncles dilated, 
and somewhat compressed towards the apex. Calyx obtuse. Corolla and stamens marcescent. 
(Don’s Mil., i. p. 602.) A deciduous undershrub, from the Canary Islands in 1779, producing its 
yellow flowers in August. Height 3 ft. It is usually treated as a green-house plant ; but it is 
ae sera resisting the winters of the climate of London, in a warm situation, with very little 
protection.

rather acute, full of pellucid dots. Calyx ovate, acute. Pe- 
duncles bibracteate. Corolla and stamens withering. (Don’s 
Mill., i. p. 602.) An interesting little shrub, with glaucous 
sessile leaves, native of Mount Olympus and China, intro- 
duced in 1706, and producing its yellow flowers from July to 
September. It ‘grows to the height. of from 1 ft. to 2 ft., and 
requires protection during winter, All the half-hardy species 
of Hypéricum might be grown on a conical piece of rockwork, 
a sort of miniature Mount Olympus, in a warm sheltered 
part of the pleasure-ground or arboretum. The protection 
required in winter might be given with complete effect, and at 
very little expense, by resting a number of poles on the pro- 
truding points of the larger rocks or stones, and on these 
placing thatched hurdles, or even, in warm districts, a few 
spruce fir branches. R

Spec. Char., &c. Stem bluntly quadrangular. Branches compressed. Leaves ovate-lanceolate, acute. 
Calyx ovate, obtuse. Styles 3—4, diverging. (Don’s Mill., i. p. 602.) A neat little shrub, a native of 
the Canary Islands, introduced in 1699, and producing its yellow fiowers from July to September. 
Height 4ft. It is commonly kept in green-houses or frames ; but, like most of the other plants from 
the Canary Islands and similar climates, it will endure a London winter in the open air against a 
_ wall, with the protection of litter or leaves over the ground, and a couple of mats over the top.

Calyx oblong, obtuse, beset with black dots. Styles collected together. (Don’s Miil., i. p. 602.) A 
sub-evergreen shrub, a native of the East Indies and the Cape of Good Hope; introduced in 1753, 
and producing its yellow flowers from March to September. Height 3 ft. It is marked in the 
' Catalogues as a green-house plant: it would, in all probability, endure the open air, with protection, 
during winter. It stood at Biel, in East Lothian, in 1825, in an exposed situation. A species bear- 
ing this name has stood against the wall in the garden of the London Horticultural Society, for four 
yous, with very little protection. There is a species, named H. monégynum L., not of Miller, which 
figured in Bot. Mag., t. 334., which appears to be different from this one. Itis a native of Japan 
! and China, and grows to the height of 3ft. In Nepal, a species nearly allied to this (H. cérnuum 
fiox., H. specidsum Wail.) is met with on hills at 3000 ft. of elevation.

without dots; flower-bearing branches leafy below, crowded _Bracteas ovate-cordate, acute. Sepals 
ovate, mucronate, without dots. Petals oblong, unequally sided, obliquely mucronulate. Stamens 
short, Styles unconnected, scarcely longer than the corolla. (Don’s Miil., i. p. 602.) A sub-evergreen 
shrub from Nepal, in 1825, producing its yellow flowers from Aprilto October. Height 2 ft. It is 
conte kept in a frame, but would stand our winters, in a warm situation, with a very little 
protection. ;
