1148 ARBORETUM AND FRUTICETUM. PART ITI. 
Dr. Horsfield. (Don’s Mill., iii. p. 844.) 
A shrub, growing to the height of from 
3 ft. to 5 ft., a native of Nepal, on Gos- 
sainthan, a high mountain to the north 
of the valley. It was raised in 1825, by 
Messrs. Loddiges, from seeds received from 
Dr. Wallich, and flowers in April. This 
species seems much less tender than any of 
the others yet received from the Himalayas ; 
and, plants having stood out in the arboretum 
of Messrs. Loddiges for several winters 
without protection, and without having re- 
ceived any injury, it may be considered as 
very nearly hardy. 
@ R. barbitum Wall., Don’s Mill., 3. p.844. Leaves oblong-lanceolate, acute, obtuse at the base, 
yellowish beneath. Calycine segments dilated, membranous. Ovarium 10-celled, glandular, hispid. 
Petioles and midrib of leaves bristly. Filaments glabrous, toothless. Leavesaspan long. Corolla 
dark red, with broad, rounded, cloven segments, Ovarium thickly beset with glanduliferous bristles. 
A tree, a native of Nepal, introduced in 1830 or before, and of which there are plants at Messrs. 
Loddiges’s, and in some other nurseries. 
# R. xeylinicum Lodd. Cat., and R. stréctum Lodd. Cat., appear to be varieties 
of R. arboreum ; but from the plants in the Hackney collection being small, 
and not having yet flowered, it is difficult to say with certainty what they are. 

B. Species not yet introduced. 
 R. formdsum Wall. Pl. Rar. Asiat., 3. p. 3. t.207., Don’s Mill., 3. p. 835., has 
the leaves lanceolate, attenuated at the base, beset with rusty dots beneath, and 
the flowers about the size of those of R. pénticum, white, suffused with red. 
It is a shrub, a native of Nepal, which is not yet introduced. 
# R. linearifolium Poir., Don’s Mill., 5. p. 844, has linear coriaceous leaves, 
and small flowersin corymbs. It is a native of the East Indies; but very little 
is known respecting it, and it may probably belong to some other genus. 
§ ii. Pogondnthum.

Sect. Char. Limb of calyx short, 5-lobed. Corolla salver-shaped, with a 
cylindrical tube, and a spreading limb. Stamens 5, enclosed. Ovarium 
5-celled. Evergreen. Leaves coriaceous.

Spec. Char., §c._ Branchlets downy. Leaves oval, rusty beneath from lepidoted 
tomentum. Corollas with a woollythroat. Shrub much branched. Leaves XN 
ending in a reflexed mucro, naked above. Flowers glomerate, sulphur-coloured. Pedicels short, 
lepidoted, and resinous. Calycine segments rounded at the apex, with villous margins. Segments 
of corolla roundish, with undulated curled margins. Filaments glabrous. Stigma clavate. (Don’s 
Mill., iii. p. 845.) A shrub, from 1ft. to 1 ft. high, a native of Nepal, on Gossainthan. It was 
introduced in 1820, and flowers in April and May. ; 
§ iii. Tsutsatsi D. Don. 
Derivation. The Chinese name of A. indica. 
Sect. Char. Limb of calyx foliaceous, 5-cleft. Corolla campanulate. Stamens 5—10. Ovarium 
5-celled. Evergreen. Leaves membranous, hispid from hairs. Indian azaleas of British gardens. 
A. Indian half-hardy Azaleas already in British Gardens.

Spec. Char., &c. Branches strigose. Leaves cuneate-lanceolate, finely cre- 
nulated, strigose, attenuated at both ends. Calycine teeth long-lan- ¢§ 
ceolate, obtuse, ciliated, spreading. Flowers terminal, solitary or twin, 
decandrous ; very showy, and scarlet or red. (Don’s Miil., iii. p. 845.) A 
shrub, from 3 ft. to 6 ft. high, a native of China and Japan, where it is 
much cultivated for the sake of its flowers. It was introduced in 1808, 
and flowers from March till May. It is a very popular plant in British 
stoves and green-houses; though, to flower profusely, it requires to be 
grown in the temperature of the bark-stove. As it cross-fecundates 
freely with the hardy species, it has led to the production of various 955 
hybrids, which are half-hardy, and some of them nearly hardy.
