Stilbocarpa polaris, A. Gray. 



" Leaves 6 in. to 12 in. broad or more, almost fleshy, bristly 

 on both surfaces, orbicular-reniform, many - lobed, strongly 

 toothed ; veins flabellate, principal veins and smaller reticula- 

 tions divide the leaf into distinctly marked areas made pro- 

 minent by the depression of the veins ; the bristles of the upper 

 surface, which may be J in. or more in length, found in these 

 areas ; on the under surface they are found on the larger veins, 

 and are more numerous."* 



" The large rhizome, measuring + 8 cm. by ± 7 cm., creeps 

 on the surface of the ground. Usually about six fully developed 

 leaves are given off from an ascending portion of the stem. 

 These leaves are + 6 cm. broad at the sheathing base, which is 

 furnished with a very large stipule + 18 cm. long by 10 cm. 

 wide at the apex, its widest part. Such stipules in part enclose 

 the interior bud, against which they are pressed tightly by their 

 concave inner surface, and play a most important part in its 

 protection. The petiole, + 54 cm. long, is thick, but hollow. 

 The leaf-blade is orbicular-reniform. It is + 19 cm. in length, 

 measuring from sinus to apex, and ± 29 cm. broad. These 

 leaf-blades are more or less in the form of a funnel, through the 

 lobes of the reniform base being bent inwards, and so convey 

 any water which falls on them to the roots of the plant. The 

 leaves on both surfaces and the petioles are furnished with 

 many pale hairs 10 mm. in length. "f

Lord Auckland Group and Campbell Island : "In the woods 

 and on banks generally near the sea, but often attaining an 

 altitude of 600 ft. to 700 ft., covering large tracts of ground 

 with its bright and shining green foliage." § "It occurs every- 

 where at low elevations on these islands, and is of a decidedly 

 antarctic type, extending from Macquarie Island to Antipodes 

 Islands."||
