 {Don's Mill., i. p. 602.) A deciduous undcrshrub, from the Canary Islands in 1779, producing its 

 yellow flowers in August. Height .') ft. It is usually treated as a green-house plant ; but it is 

 capable of resisting the winters of the climate of London, in a warm situation, with very little 

 protection.

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 fi., and 



requires protection during winter. All the half-hardy species 



of //vptricuni 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 eftect, 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.

 the Canary Islands, introduced in 1699, and producing its yellow flowers from July to September. 

 Height 4 ft. It is conimoiilv kept in green-houses or frames ; but, like most of the other plants trom 

 the Canary Isl:inds 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.

 sub-evergrcen shrub, a native of the East Indies and the Cape of Good Hope ; introduced in 1/.%, 

 and producing its yellow flowers from March to September. Height 3 It. 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 

 years, with very littU- protection. There is a species, named H. mondgyniim L., not of Miller, which 

 'is figured in Hot. Mag., t. 3*4., which appears to be different from this one. It is a native ot Japan 

 and China, and grows to the height of 3 ft. In Nepal, a species nearly allied to this (H. cernuum 

 Rox., H. speciosum JVall.) is met with on hills at 3000 ft. of elevation.

 shrub from Nepal, in 1825, producing its yellow flowers from April to October. Height 2 ft. It is 

 commonly kept in a frame, but would stand our winters, in a warm situation, with a very little 

 protection.
