small bracts. This has more the habit of a Senecio than of a Notonia, but the styles 

 are characteristic of the latter genus. Thwaites describes the flowers as pale yellow 

 in Ceylon, and Wight as white in the Nilgherries. 



DOUBTFUL SPECIES. 



N. CBASSISSIMA, DC. Prodr. vi. 442; Kurz in Journ. As. Soc. 1877, ii. 194 (Cacalia 

 crassissima, Wall. Cat. 3155); Wallich's specimen of this (from the Segaen hills, Ava) 

 has no flowers, and the branches and leaves do not differ from those of N. grandiflora. 

 Kurz, who keeps it up, gives Wallich's habitat, and quotes Griffith's Ic. PL Asiat. t. 

 470, as the same plant ; but that figure is utterly unlike any known plant. So many 

 Deccan plants are A van, that this is probably N. grandiflora. 



79, SENECIO, Linn. 



Herbs, undershrubs or shrubs. Leaves radical or alternate, entire or 

 variously divided. Heads solitary corymbose or racemose, heterogamous 

 (rarely hoiuogamous) usually yellow ; ray-fl. <j> , fertile, ligulate (or 0) ; disk-fl . 

 , fertile, tubular, 5-fid. Involucre various, bracts 1 or sub-2-seriate, equal, 

 erect, free or connate at the base, with few or many very short outer ones (heads 

 bracteolate) ; receptacle flat or convex, naked, pitted or fimbrillate. Anther-bases 

 obtuse, or auricled, or minutely tailed. Style-arms of g recurved, tips truncate 

 and penicillate, rarely rounded or with a short narrow point. Achenes subterete 

 or outer dorsally compressed, 5-10-ribbed ; pappus-hairs copious or sparse, soft, 

 white, smooth, scabrid or barbellate. DISTRIB. About 900 species, chiefly in 

 temperate climates and mountains of the tropics. 



I have refrained from regarding various Indian species of the section Jacob&a as 

 forms or varieties of North Asiatic and European, the limits of these being so badly 

 defined that a study of the whole genus would be necessary to do so with confidence ; 

 of the other sections the species are certainly almost all South Asiatic. Amongst the 

 Indian anomalous species are those of the group of Madaractis, hitherto referred to 

 Doronicum, whose pappus is usually red and rigid ; amongst these the most remarkable 

 are 8. Grahami with paleaceous pappus, and 8. belgaumensis with none at all. The 

 many-seriate, imbricating, involucral bracts of 8. lavandulcefoliics in its ordinary 

 state are altogether unlike those of the genus, and the species is referable to Senecio 

 only on the (tenable) hypothesis of the bracteoles being very numerous and appressed 

 to the involucral bracts. 



SERIES A. Anther-cells obtuse at the base, not produced downwards into 

 tails. 



SECT. I. Jacobaea. Erect herbs. Heads usually campanulate ; in vol. 

 bracts 1-seriate, subequal ; ligules usually conspicuous, rarely minute, in 15. 

 dubius. Achenes all pappose (except forms of 2. chrysanthemoides and 5. diversi- 

 folius) ; pappus longer than the achenes, of soft white (rarely red) equal hairs. 



* Annuals or biennials. Disk.-fl. with a funnel-shaped or campanulate limb: 

 Leaves broad or narrow, entire toothed or lyrate-pinnatifid. 



1. S. graciliflorus, DC. Prodr. vi. 365 ; glabrous, erect, stem flexuous 

 terete or nearly so, leaves large petioled pinnatifid, lobes 6-8 pair ovate- or 

 oblong-lanceolate acuminate coarsely unequally serrate, petiole not auricled, 

 heads ^ in. many narrow bracteolate 5-8-fld. in much branched corymbs or 

 panicles, invol. bracts 5-7 linear obtuse glabrous, ligules 3-5, achenes ribbed 

 glabrous all pappose. Clarke Comp. 2nd. 189. S. Royleanus, DC. I. c. 367.
