S. Helleri, nov. sp., frutex; raraulis molliter pilosis; novellis albo- 

 pilosissimis, foliis oppositis bi-tripinnatisectis supra viridibus pills brev'is- 

 simis couicis scabriusculis subtus paulo pallidioribus glanduloso-puberulis 

 et in nervis hirsutis ; pedunculis ad apicem ramuli saepe tribus quam 

 folii muko brevioribus ; capitulis eradiatis; involucri hemisj^haerici squamis 

 oblongis apice rotundatis obsolete striatis ; floribus omnibus ^ numerosis : 

 corollas puberulae tubo propriori gracile brevi in fauces conspicuas 

 longas rectas ampliato ; achenio oblongo valde compresso apice truncato 

 calvo ; paleis apice 2-3-dentatis, dentibus laciniato-ciliatis ad apiculum 

 abrupte angustatis. — Bakrixgtox Isl. : May, 1899, Snodgrass & 

 Heller, no. 466 (hb. Gr.). Endemic. Leaves 8 cm. long, 5 cm. broad; 

 petioles 1.5 to 2 cm. long covered with rather soft and widely spreading 

 pilosity : heads 1.8 cm. in diameter. "Well marked by its very deeply 

 cut foliage and rounded involucral bracts. Plate 1, figs. 9 and 10. 



S. Hopkinsii, nov. sp., frutex ; ramis teretibus pallide brunneis 

 pilosis in specimine siccato striatulis ; ramulis pilosissimis foliosis plus 

 minusve gummiferis ; foliis ovatis planis tenuibus molliter pubescentibus 

 subtus pallidioribus subargute pinnati-lobatis, apice acutis basi subintegris 

 acutatis ; lobulis dentatis ; pedunculo gracile a foliis superato piloso ; 

 capitulis eradiatis ; involucri hemisphaerici squamis oblongis obovatisve 

 acutis villosis leviter striatis ; floribus omnibus ^ ; corollae tubo gracili 

 saepe curvato baud vel paulo in fauces ampliato pubescenti ; achaenio 

 glabro compresso griseo calvo. — Abingdox Isl.: 520 m. alt., June, 

 1899, Snodgrass & Heller, no. 851 (hb. Gr.). Endemic. Leaves 8 cm. 

 long, half as broad. Petioles 2 cm. long. Heads 1.2 cm. in diameter. 

 "With its thin flat soft-pubescent leaves this can scarcely be Mr. Hemsley's 

 S. retrojlexa nor does it agree with any of the other species heretofore 

 characterized. Although near S. incisa, Hook, f., it has more ovate 

 leaves and acuter involucral bracts than that species. Plate 3, fig. 1.
