152 HARDY ORNAMENTAL 



with broadly campanulate rosy-purple flowers, spotted with 

 yellow. 



R. oampanulatdm {syn R. mruginosum). — Sikkim, 1825. 

 Small-growing species, rarely over 6 feet high, with elliptic 

 leaves that are fawn-coloured on the undersides. The 

 campanulate flowers are large and showy, rose or white 

 and purple spotted, at the base of the three upper lobes- 

 In this country it is fairly hardy, but suffers in very severe 

 weather, unless planted in a sheltered site. There are 

 several good varieties. 



R. campylocarptjm. — Sikkim, 1851. This has stood the 

 winter uninjured in so many districts that it may at least 

 be recommended for planting in favoured situations and by 

 the seaside. The leaves are about 4 inches long, 2 inches 

 wide, and distinctly undulated on the margins. Flowers 

 bell-shaped, about 2 inches in diameter, and arranged in 

 rather straggling terminal heads. They are sulphur-yellow, 

 without markings, a tint distinct from any other known 

 Indian species. 



R. catawbiensb. — Mountains from Virginia to Georgia, 

 1809. A bushy, free-growing species, with broadly oval 

 leaves and large campanulate flowers, produced in compact, 

 rounded clusters. They vary a good deal in colour, but 

 lilac-purple is the typical shade. This is a very valuable 

 species, and one that has given rise to a large number of 

 beautiful varieties. 



R. chevsanthtjm is a Siberian species (1796) of very 

 dwarf, compact group, with linear-lanceolate leaves that 

 are ferruginous on the underside, and beautiful golden- 

 yellow flowers an inch in diameter. It is a desirable 

 but scarce species. 



R. Collettianum is an Afghanistan species, and one 

 that may be reckoned upon as being perfectly hardy. It is 

 of very dwarf habit, and bears an abundance of small white 

 and faintly fragrant flowers. For planting on rockwork it 

 is a valuable species.
