ampliato: limbo breviter 5-dentato albo-puberulo: achenio puberulo 
compresso breviter oblongo apice calvo. — NarBoroueHu Ist.: northern 
part, Snodgrass & Heller, no. 297 (hb. Gr.) ; southern part, common at 
650 m. alt., Snodgrass & Heller, no. 341 (hb. Gr.). Endemic. Leaf- 
blade 6 to 11 em. long, half as broad, petioles 1 to 1.5 cm. long: heads 
2 cm. in diameter ; ray-flowers including the achene 12 mm. long. This 
species approaches S. affinis, Hook. f., but differs in its alternate more 
finely toothed leaves, in the branched lateral leaf-nerves which (if the 
figure in Hook. Icon. t. 2718 be correct) are simple and marginal in 
S, affinis. S. affinis would from the figure seem furthermore to have a 
longer more hirsute type of pubescence. Prats 3, rics. 4, 5, 6, and 7.

S. Snodgrassii, nov sp. 8. Baurii et S. retroflexae affinis, fruticosa, 
6-9 dm. alta; ramis teretibus glabrescentibus foliosis in specimine siccato

puberulis; foliis planiusculis alternis ovato-oblongis penninervatis supra 
pilis minutis conicis albis obstitis subtus paulo pallidioribus tenuiter 
pubescentibus pinnatisectis; lobis obtusissimis et obtuse dentatis sinis

tribus gracilibus saepius unibracteatis puberulis et parce pilosis ; capitulis 
eradiatis ; involucri hemisphaerici squamis obovato-oblongis brevissime — 
acuminatis 3—5-nervatis pubescentibus et breviter ciliatis; floribus om- 
nibus 8; 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. — Wenman Isi.: 8 
December, 1898, Snodgrass & Heller, no. 10 (hb. Gr.). Endemic. This 
Species is probably nearest S. retroflexa recently described by Mr. Hems- 
ley from Indefatigable Island. That, however, has the leaves recurved 
and somewhat crisped, of slightly different dentation and a corolla de- 
cidedly ampliate in the throat; also villous petioles. S. Baurii differs ° 
in its rugulose leaves, S. Hopkinsii in its very different indumentum, 
and S. inecisa in leaf contour and the bluntly toothed chaff. PLATE 3,
