ong been thought possible that tree-ferns might extend to 
the Snares, but none were observe e extreme southern limit 
of tree- frtin therefore is the South Cape of Stewart Island, in 
8. latitude 47° 20’, instead of 45° 50’, as usually stated in our text-

A few naturalised plants have been introduced by the sealers, 
and four or five indigenous species from the mainland have become 
island was under thirty, but my visit was too brief to allow of an 
ean examination being made; it is not probable that any 
large number of species will be added. 
Mosses are exceptionally rare; a few Lichens were observed, 
but no Fungi or Hepatice. No opportunity of collecting Marine 
Alge was afforded 
I append a description of the more remarkable species :— 
igusticum acutifolium, sp. n.—A stout herb 3-5 ft. high, 
rootstock as thick as a man’s wrist. Leaves 2 ft. long or more, 
6-9” broad, oblong or ovate-oblong, tripinnate ; segments large, 
acute ; petiole with the upper part of the sheath free, forming a 
ligule. Stem stout, much branched ; flowers not seen. Fruitin ng 
umbels 2” 24” diameter, compound, dense; carpels ;3,’’ long, 
ret the pedicels, 3-5-ribbed. 
Hab. Th 
e species, allied to L. intermedium Hook. f. and 
t 
ligulate petiolate sheath; and from both alike by the absence 
of viscid, milky juice. The sheathing bracts are leafy at the tips 
and unusually large, sometimes exceeding the flowering branches. 
Arata Lyatin T. Kirk, var. ropusta.—More robust and less 
hispid than the type. Stolons absent. Petioles above 
convex below, solid or nearly so; teeth more strongly mucronate. 
Flowers cra Spree: alsitae, dull yellow 
The Snares. 
The typical uae which is found on Stewart Island and islands 
in Foveaux Strait, has softer and more hairy foliage ; terete, thin- 
walled, fistulose petioles ; lurid, purple flowers; stout stolons as 
thick as a man’s finger, and which are at first erect. No difference 
is presented in the form of the leaves, the curious tubular ligule at 
the base of the petiole, nor in the structure of the fruit. 
Deschampsia gracillima, sp. n. — An erect, tufted, ers 
toothed, or else with a short dorsal awn inserted just below the apex; 
paler, minutely ciliated; rachilla silky ; ladieules 3; grain free.
