Ligularia clivorum, Maxim. Mel. Biol. vol. vii. p. 555. 



Senecio clivorum is certainly the handsomest of all the 

 herbaceous species of the genus, and will no doubt 

 become a very conspicuous feature in the hardy her- 

 baceous garden. It is referable to the section or sub- 

 genus Ligularia, and its nearest affinity is to the Japanese 

 L. Hodgsoni, Hook. (Bot. Mag. t. 5417), which differs in 

 having lobed, coarsely toothed leaves, and more numerous, 

 pale yellow ray-florets. Both are remarkable for their very 

 rigid red-purple pappus, of a totally different character 

 from the soft, white pappus of typical Senecio. 



Senecio clivorum varies much in the size of the flower- 

 heads and ray-flowers, in the amount of pubescence on 

 the inflorescence, and in the bracts of the involucre, 

 which are obtuse, acute or acuminate. In the Chinese 

 specimens, but not in the Japanese, 1 find the ray-corollas 

 bearing five filaments (see fig. 1), representing the stamens 

 of the disk-flowers, a character which has been observed 

 in other species of the section. The species was dis-
