A tall herb, l è - 2 feet high, everywhere woolly or cobwebby with scattered white down, branched at the top
into a veiy many-headed corymb, leaves 3 -5 inebes long, narrow, linear, oblong or obovate ; the lower generally
contracted into a long petiole ; upper (sometimes all) sessüe. with a broadly two-lobed stem-claspinv base- margins
unequally toothed, lobed or pinnatifid, with the lobes again toothed; upper surface nearly smooth ’ lower
densely clothed with white wool; uppermost leaves at the axils of the corymb, subulate, with broad two-lobed
toothed bases. PeduncUs and pedicels woolly. Imoluores woolly at the very- base only, simüar to those of th¡
former species. Achenia grooved, pubescent or papillose on the rid g e s .-T h is is also a very common Australian
and Tasmanian plant, always varying veiy much in the breadth and lobing of the leaves.

Veqi similar to E. arguta, but generally a smaller plant; the New Zealand specimens are not woolly but
covered eveq-where, except the pedicels and involucres, with short, white, scattered, hispid hairs. Leaves more or
less lobed and cut, 2-3 inches long, linear-oblong, sessüe or narrowed into short petioles, having two small toothed
lobes at the base, half-claspmg tbe stem. Corymbs and eapUula as in E. aryuta ; but the achenia are lonrar and
have at the top a callous ring surrounding the base of the pappus, as in E. prenanthoides.— T i h is also a New llol
land and Tasmanian plant, but the specimens from the latter country are woolly as well as hispid. Those firared
by Richard have the leaves nearly entire. °

Whole plant more or less clothed with loose white wool, except the pedicels and involucres. Sterræ simple or
branched, 3-3 feet higli. Leaves rather stiff, very long and narrow, 2 -8 inches long, often much crowded on the
stems, l^<^h broad, sharp, margins recurved, very woolly below, cobwebby above, quite entire or with a tooth on
each side at the base, where they are sessile on the stem. Corymbs spreading, with very slender branches. Involucres
much larger than in any of the former species, nearly 4 inch long, naiTow ; scales very slender, green. Achenia longer
than in any New Zealand species, deeply grooved and ribbed, the ribs pubescent, contracted below the tip, with an
obscure ring at the apex.—Found in common with all the preceding both in Australia and Tasmania.

One of the largest kuown genera of plants, scattered over the whole surface of the globe, but rare in tropical
iflains and in very cold regions ; it contains upwards of 300 species. The individual species have not Avide ranges,
b ut are extremely variable and are ofteu difiicult to define. The majority are herbs, but some form bushes, and a
few are small trees.— Capitula yellow, many-flowered. Florets of the circumference female, ligulate, or like those of the
disc ; those of the disc tubular, campanulate above, herraaplirodite, five-cleft ; anthers exserted. A rm o f the styles
of the* disc-ilorets truncated, downy at the tip only ; those of the ligulate florets linear, rounded, blunt, smooth.
Involucre broadly hemispherical or oblong, of one series of long, green, herbaceous scales, usually brown at the tips,
as long as the disc, and with a few much smaller scales at their base. Receptacle convex, papillose. Achenia
smooth or hairy, often ribbed. Pappus of two or more series of soft, slender, roughened or rigid and scabrous,
usually snow-white hairs.—This and Celmisia are the handsomest genera of New Zealand herbaceous plants.
Dr. Lyall’s discoveries have added the most magnificent species of each from tbe Middle Island. (Name from senex,
an old man ; in allusion to the white hairy pappus.)
