228 THE JOUK^'AL OF 1J0TA>'T 



S. aiyssinicus Sell. Bip. with dissimilar foliage and i*adiate heads 

 is a close allj of this, which Mr. Gossweiler notes as appearing 

 "always in colonies, but only in few localities" — hence the trivial 



Senecio (§ Plais'tagiis'ei) adustus, sp. nov. Caul Hits e rhizo- 

 mate crasso cajspitosis semispithanieis siiiiplicibus suhdistanter foliosis 

 pnbenilis ; foliis radicalibus longe valideque petiolatis caulinis parvis 

 sessilibus linearibus obtusis puberulis ; caj)itulis sat magnis solitariis 

 terminalibus homogamis diseoideis co -liosculosis ; involucri hemi- 

 sphterici glabri phyllis 20 anguste lineari-lanceolatis acuminatis 

 dorso carinatis margine scariosis additis paucis lanceolatis vel etiam 

 ovato-lanceolatis acviminatis calyculum efficientibus ; corollis 5-meris 

 albis exsertis tubo gracili sub apice campanulatim dilatato ; genitaU- 

 hus exsertis ; styli ramis truncatis penicillatis ; ochceniis (nondum 

 maturis) oblongis glabris ; pappi setis leviter seabriiiseulis albis. 



Benguella, common in the moist depression east of Keiando, along 

 the carriers' path to Boca Varaquanha, and in open primary woods 

 near the Cubal rivulet in company of two perennial Proteacea? ; 

 Oos^uieiley, 1749. 



Rhizoma circa 1 cm. crass. Foliorum radicalium petiohis saltern 



15 cm. long., prominenter striatus; limbus . Caules 10-12 cm. 



alt., sat graciles ; horum folia 1-1 "5 cm. long., 2-4 mm. lat., suiiima 

 capitulum fere attingentia. Capitula pansa circa 18 x 18 mm. 

 Calyculi phylla 5 mm. long., 2'5-4 mm. lat. Involucri phylla 

 15 mm. long. Corolla? tubus basi leviter ampliatus, pars angusta 

 12 mm. long., pars campanulata 2"5 x 2'5 mm. ; lobi triangulares, 

 obtusi, 1'5 mm. long. Androecium fere usque 2 mm. exsertum. 

 Styli rami 2 mm. long. Aehfenia 2 mm., pappus 10 mm. long. 



To be inserted in the genus near >S'. albanensis DC, but too 

 distinct to require particulars. 



The radical leaves are represented only by the rigid persistent 

 portions of their stalks, wdiicli have evidently been subjected to the 

 action of tire. Mr. Gossweiler's note states that the flowering stems 

 spring up after the " queimadas " or bush-fires have* passed over the 

 habitat.
