314 This plant is certainly not indigenous to the Southern Hemisphere ; but carried to the Falkland Islands, where it is widely dispersed. 9. Senecio Kingii, Hook. fil. ; herbaceus, glaberrimus, caule simplici brevi decumbente folioso scapigero, foliis petiolatis ad avjicem caulis fasciculatis carnosis liiieari-spatbulatis grosse dentatis, scapo erecto solitario 1-cephalo fokis 2-3 subulatis aucto superne puberulo, capitulo late campanulato, involucri squamis glaberrirnis lineari-lanceolatis disco brevioribus.

Hab. Strait of Magalhaens, Port Famine ; Capt. King.

Caulis 1-2-pollicaris, teres, crassitie pennse corvinae, basi decumbente nudo, apice ascendente folioso. Folia perplurima, fasciculata, basi vaginantia et imbricata, 1-1-i-uncialia, gradatim dilatata, grosse serrato-dentata, plana. Scopus erectus, teres, siccitate sulcatus, 3-4-pollicaris, foliis parvis subulatis filifonnibusve auctus. Capitulum inclinatmn, i-f unc. longum, late campanulatum. Involucri squama? lineari-lanceolatse, glaberrimas, sub 1-seriales basi squamulis paucis subulatis suffultae, disco breviores.

Capt. King's specimens of this apparently distinct species are the only ones I have ever seen, it is truly scapigerous, allied in habit to the S. trifurcatus, Less., which has radiate flowers, and still more nearly to S. crithnoides, H. and A., of Mendoza, which is suffratescent and branched below.

10. Senecio Arnottii, Hook. fil. ; glaberrimus v. obsolete glanduloso-puberulus, erectus, suffrutescens, ramis erectis foliosis simpkcibus, foliis solitariis subfasciculatisve coriaceis late linearibus v. oblongo-lineari-lanceolatis acutis integerrimis marginibus revolutis costa subter puberula, corymbis terrniualibus 4-12- ceplialis, pedicellis elongatis foliolis subulatis bracteatis, capitulis late carnpaiiulatis, involucri squamis anguste lineari-lanceolatis acurniuatis. S. limbardioides, Hook, et Am. in Bot. Jotim. vol. iii. p. 347.

Hab. Strait of Magalhaens, Port Famine; Capt. King.

Rami stricti, erecti, petioli pedicellique sub leute pube sparsa obscure glandulosa operti. Folk l- unc. longa, 2-3 lin. lata, sessilia, coriacea v. subcarnosula, plana v. plermnque marginibus recurvis, e ramulis axfllaribus abbreviatis foliiferis quasi fasciculata. Pedicelli erecti, li- 2-unciales, foliis subidatis linearibusve acuminatis bracteolati. Capitula unc. longa, latiora quam longa.

Allied to 8. Uttoralis, Gaud., a radiate-flowered species. One specimen from Chiloe, collected by Mr. Darwin, has broadly linear leaves, a few of which shew a tendency to become toothed towards the apex. The name of S. Umbardioides, having been through inadvertence twice used in the Botanical Journal (1. c), I have changed that of this species.

11. Senecio longipes, Hook. fil. ; glabriusculus v. superne pracipue glanduloso-pubescens, ramis erectis simplicibus strictiusculis, foliis plerisque fascicidatis anguste linearibus filiformibiisve acutis basi attenuatis apicem versus serratis marginibus revolutis, corymbis 3-7-cephalis, pedicellis valde elongatis, bracteolis sabulato-filiformibus, capitulis late carnpaiiulatis, involucri squamis 1-serialibus glandulosis disco brevioribus.

Hab. Strait of Magalhaens, Port Famine ; Capt. King.

Priori affinis sed gracilior, foliis inultoties angustioribus dentatis pedicellisque valde elongatis.

All Capt. King's specimens agree in possessing much narrower leaves and longer pedicels than the former species, so that, though probably oidy varieties of one plant, I am unable to prove them so.

12. Senecio miser, Hook. fil. ; suffruticosus, depressus, pubescenti-viscosus, caule ascendente ramoso cicatricato, ramis suberectis breviusculis foliosis, foliis coriaceis subcrispatis anguste lineari-spathulatis irre-
