ARBORETUM AND FRUTICETUM. 



TART III. 



Dr. Horsficld. (Z>on's Mill., iii. p. 844.) 

 A shrub, growing to the height of from 

 3 ft. to 3 ft., a native of Nepal, on Gos- 

 sainthan, a high mountain to the north 

 of the valle}'. 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. 



J R. harbutum Wall., Don's Mill., 3. p. 844. Leaves obloHB-lanccolatc, acute, obtuse at the base, 

 yellowish beneath. Calycine segments dilate<l, membranous. Ovarium ll>-cclle<l, glanilular, hispid. 

 Petioles and midrib of leaves bristly. Filaments glabrous, toothless. Leaves a span 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. 

 IjOddiges's, and in some other nurseries. 



41 K. zei/liUiiciim Lixld. Cat, and K. slriclum Lodd. Cat., ai>i>ear to Iw varieties 

 of H. arbi'iicum ; but from the plants in the Hackney collection l>eing small, 

 and not having yet flowered, it is ditlicult to tay with certainty what tliey are. 



B. Species not yet introduced. 



m R. formbsum Wall PI. Rar. Asiat., 3. p. 3. t 207., Don's Mill., 3. p. 8.15., has 

 the leaves lanceolate, attenuated at the base, beset with rusty dots bene.ith, and 

 the flowers about the size of those of 1(. p6nticum, white, sutTused with red. 

 It is a shrub, a n.itivp of Nepal, which is not yet introduced. 



• R. lincarifhliiim Poir., Don's Mill., 3. p. 844., has linear coriaceous leaves, 

 and small flowers in 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. Pogonanthiim.

 Sect. Char. Limb of calyx short, .5.lobed. Corolla salver-shaped, with a 



cylindric.ll tube, and a spreading limb. Stamens 5, enclosed. Ovarium 



5-ccllcd. Evergreen. Leaves coriaceous.

 ending in a reflexed mucro, nakc<i above. Flowers glomerate, sulphur-coloured. Pedicels short, 

 Iepidote<l, and resinous. C.ilycine segments rounded at the apex, with villous margins. .Segments 

 of corolla roundish, with undul.ited curletl margins. Filaments glabrous. Stigma cjavate. (Don's 

 Mill., iii. p. 845.) A shrub, from 1 tt. to 1| ft. high, a native of Nepal, on Gossainthan. It was 

 introduced in 1820, and flowers in April and May. 



§ iii. Tsutsutsi D. Don. 

 Derivation. The Chinese name of A. indica.

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, 

 dec.indrous ; very showy, and scarlet or red. (Don's Mill., iii. p. 84.").) A 

 shrub, from 3 ft. to fi ft. high, a native of China and Japan, where it i.i 

 much cultivated for the sake of its flowers. It was introduced in 1S(I8, 

 and flowers from March till May. It is a very i>opular 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 J J J 

 hybrids, which are half-hardy, and some of thom nearly hardy.
