ampliato : limbo breviter 5-deutato albo-puberulo : achenio jjuberulo 

 coinpresso breviter oblougo apice culvo. — • Narborough Isl. : northern 

 part, Snodgrass & Heller, no. 297 (lib. Gr.) ; southern part, common at 

 G50 m. alt., Snodgrass & Heller, no. 341 (hb. Gr.). Endemic. Leaf- 

 blade 6 to 11 cm. long, half as broad, petioles 1 to l.o cm. long: heads 

 2 cm. in diameter; ray-flowers including the achene 12 mm. long. This 

 species approaches S. affims, Hook, f., but differs in its alternate more 

 finely toothed leaves, in the branched lateral leaf-nerves wliich (if the 

 figui-e in Hook. Icon. t. 2718 be correct) are simple and marginal in 

 aS". ajfinis. S. affinis would from the figure seem furthermore to have a 

 longer more hirsute type of pubescence. Plate 3, figs. 4, 5, G, and 7.

1^ S. Snodgrassii, nov sp. S. Baurii et S. retrojlexae affinis, fruticosa, 

 6-9 dm. alta ; ramis teretibus glabrescentibus foliosis in specimine siccato

 acuminatis 3-o-nervatis pubescentibus et breviter ciliatis ; fioribus om- 

 nibus ^ ; corollae tubo gracili hispidulo-puberulo saepius arcuato in 

 fauces dilatato; limbo 5-dentato recurvato ; achenio compresso griseo 

 glabro apice subtruncato obsolete 2-dentato ; paleis striatis conduplicatis 

 argute 2-3-dentatis tenuiter parceque puberulis. — Wenmax Isl.: 8 

 December, 1898, Snodgrass & Heller, no. 10 (hb. Gr.). Endemic. This 

 species is probably ueai-est S. retmjlexa recently described by ]\lr. Iloms- 

 ley from Indefatigable Island. That, however, has the leaves recurved 

 and somewhat crisped, of slightly diflerent dentation and a corolla de- 

 cidedly am|)liate in the throat; also villous petioles, S. lianri i AWXars 

 in its rugulose leaves, S. Hop/cmsii in its very different indumeniura, 

 and S. incisa in leaf contour and the bluntly toothed chaff. I'latk 3,
