ampliato : limbo breviter 5-dentato albo-puberulo : aclienio puberulo 

 compresso breviter oblongo aplce calvo. — Narborougii Isl. : iiortlieni 

 part, Snudgross & Heller, no. 297 (hb. Gr.) ; southern part, common at 

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

 blade G to 11 cm. long, half as broad, petioles 1 to 1.5 cm. long: heads 

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

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

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

 figuie in Ilook. Icon. t. 2718 be correct) are simple and marginal in 

 S. ajfinis. S. offinis would from the figure seem furthermore to have a 

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

S. Snodgrassii, nov sp. S. Baurii et *S'. retrojlexae affinis, fruticosa, 

 G-9 dm. alta ; ramis teretibus glabrescentibus foliosis in specimiiie siccato

 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 Isl. : 8 

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

 species is probably nearest S. retmjiexa 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'. i?a Mr /«' differs 

 in its rugulose leaves, S. Hophinsii in its very different indumentum, 

 and S. incisa in leaf contour and the bluntly toothed chaff. Plate 3,
