2. R. parvifolius, Linn.; DC. Prod. ii. 564 ; Bot. Reg. t. 496. Branches 

 and petioles pubescent, with small hooked prickles. Leaves pinnate, with a 

 common petiole of 1 to 2 in. Leaflets 3, or veiy rarely 5, nearly orbicular, 

 about 1 in. long, or in luxmiant shoots, the terminal one 1^ or near 2 in. 

 long, deeply and irregularly toothed, rather thin, glabrous, or nearly so, above, 

 white and cottony underneath. Plowers few, in terminal panicles. Sepals 

 about 2 lines long, softly hoary inside and out. Petals pink, but little longer. 

 Truit globular, the caqDels glabrous or very slightly hairy. 



In raviues, Champion and others. Extends from S. China to Loochoo. The Himalayan 

 plant usnally referred to this species, appears to me to be much nearer to the R. lasiocarpos ; 

 the leaHets are almost always 5, much more ovate in shape, usually acute, and the carpels 

 more pubescent or hairy. 



3. R. leucanthus, Hance in TFalp. Ann. ii. 468. The stems and petioles 

 armed with hooked prickles, and as well as every other part of the plant, per- 

 fectly glabrous. Leaves pinnate, with 3 leaflets, or a few of the upper ones 

 reduced to a single one. Leaflets ovate, acuminate, serrately toothed, the larger 

 ones 2 to 3 in. long, the lateral ones usually smaller. Flowers 2 to 5 togetlier, 

 on a short axillary common peduncle. Pedicels about 4 lines long. Sepals 

 ovate, smooth, about 4 lines long, closing over the fruit. Petals wUite. — 

 R. glaberrimits, Champ, in Kew Journ. Bot. iv. 80. 



In low grounds and ravines of the hills, CJtampion, Hance, Wright, Wilford. Not yet 

 found out of the island. The two names were both published early in 1852, one at Berlin, 

 the other in Loudon, and the latter, by Champion, on the 1st March, certainly prior to the 

 reception in this country of the part of Walpers' Annales which contained Hance's name 

 and diagnoses. As however Dr. Seemann states that the latter was actually first published, 

 I have here adopted it. 



3. SPIRJEA, Linn. 



Calyx free, persistent, 5-lobed. Petals 5. Stamens numerous. Carpels 



3 or more, usually 5, quite free from the calyx and disk, with 2 or more ovules 

 in each, and becoming, when ripe, small dry capsules, opening along the inner 

 edge, each containing 2 or more small seeds. — Shrubs or herbs, without 

 prickles. Leaves simple or divided. Plowers usually small and numerous, 

 in terminal cymes, corymbs, or panicles. 



A considerable genus, spread over the northern hemisphere both in the New and the Old 

 World, but scarcely penetrating into the tropics. 



\. S. cantonlensis, Lour. M. Cochinch. 322. A shrub of 3 or 4 ft. in 



height, with weak spreading branches, glabrous or very slightly hoary. Leaves 

 lanceolate or oblong, 1 to near 2 in. long, coarsely toothed or slightly lobed 

 above the middle, narrowed at the base into a petiole of about 2 lines. Flowers 

 rather small, white, in terminal racemes, but with the axis so short as to l)e 

 almost reduced to flat-topped corymbs or umbels, the very slender pedicels, 



4 to 6 lines long, starting from nearly the same point. Carpels 5, or very 

 rarely 6. — S. lanceolata, Poir. Diet. vii. 354, but not the plant ligm-ed as such 

 by Cambessedes in Ann. Sc. Nat. Par. ser. 1, i. t. 25, nor that described by 

 Seringe in DC. Prod. ii. 542. S. coryni.bosa, Roxb. Fl. Ind. ii. 512, but not 

 of Eafin. S. Reevesiana, Lindl. Bot. Ueg. 1844, t. 10. 



Hongkong, Wright; and other parts of S. China, but not known from elsewhere. Rox- 

 burgh's indication of the north of India is probably founded on some mistake, and the
