same treatment as the former, it flowered profusely in the 

 Society's Garden, last April. 



4. R. petiolare : inerme, foliis cordato-trilobis serratis utrinque punctato-glan- 

 dulosis, petiolis longissimis, racemis erectis elongatis, calycibusplaniusculis: laciniis 

 linearibus petala integerrima cuneiformia triplo excedentibus, baccis glabris. 



Bush erect and branching, from four to six feet high, with 

 white bark ; the young branches sprinkled with yellow small 

 glandular dots. The leaves are on very long footstalks, heart- 

 shaped, three-or imperfectly five-lobed, coarsely serrated, 

 smooth and glaucous on both sides, veiny, covered with 

 minute crowded drops of a golden-colored exudation, which 

 diffuses a powerful aromatic odour, like that of R. nigrum. 

 The flower-stalks are erect, long, but somewhat shorter than 

 the leaves, many flowered, white, and fragrant, with minute, 

 deciduous bractece. Calyx flattish, with spreading lanceolate 

 segments. Petals ovate, three times shorter than the limb. 

 Berries spherical, black and glossy, juicy, slightly astringent, 

 but not unpleasant. 



This species, has in many respects, a considerable affinity 

 to R. nigrum, particularly in its fruit : and is still more nearly 

 related to R.fragrans of Pallas in its general habit, in the 

 leaves and in the form and colour of the flower. That spe- 

 cies is however of more humble growth, with red berries of 

 greater size, and extremely sweet and pleasant to the taste. 

 R. Hudsonianum, a new species, abounding near the banks of 

 streams that flow into Hudson's Bay, is also akin to it, but 

 is diminutive, with pubescent racemes, and villous calyxes.
