hairs on the youngest leaves and miexpanded corymbs. Leaves 3-5 inches loug, iiiembraiioiis. lincav-obloiig,
often very narrow, acuminate; the lower petiolate; upper sessile, expanded at the base into broad lobes, which half

large m fiilly formed specimens, 6-10 inches across, of very numerous capitula, i inch long. Imolueres quite smooth.
Achenui Imear-ohlong, grooved, the ribs hafo, surmounted by a c,allons ring that surrounds the base of the pappiis.-

H.1B. Throughout the Islands; abundant. Banks and Solander, etc.
A tall herb, 14-2 feet high, everywhere woolly or cobwebby with scattered white down, branched at the top
into a very many-headed corymb, Uaves 3-5 inches long, narrow, linear, oblong or obovate ; the lower generally
contracted into a long petiole ; upper (sometimes all) sessile, with a broadly two-lobed atem-claspinv base ■ margins
unequally toothed, lobed or pinnatifid, with the lobes again toothed; upper surface nearly sniooth ’ lower
densely clothed with white wool; uppermost leaves at the axils of the corymb, subulate, with broad, two-lobed
toothed bases, Pednnchs and pediceU woolly. Involucres wooUy at the veiy base only, similar to those of thé
former species. Achania grooved, pubescent or papiUose on the ridges.-TMs is also a very common Australian
and Tasmanian plant, always varying very much in the breadth and lobirg of the leaves.

Hab . Northern and Middle Islands. Bay of Islands to Akaroa, PL Urville, Oanninyham, etc '.
Veiy similar to E. arguta, but generally a smaller plant; the New Zealand specimens are not woolly but
covered eveiywhere. except the pedicels and involucres, witb short, white, scattered, hispid Imirs. Leaves more or
ess lobed and cut, 2-3 inches long, linear-oblong, sessUe or narrowed into short petioles, having two small toothed
lobes at the base, balf-elasping the stem. Corymbs and capitula as in E. aryuta ; bnt the achenia are lonrer and
have at the top a callous ring surrounding the base of the pappus, as in E. prmanthoides.— Tiàs is also a New Holland
and Tasmanian plant, but tbe specimens from the latter country are woolly as well as hispid. Those fiinired
by Richard have the leaves nearly entire. °

H a b . Northern and Middle Islands; common in dry hilly places. Banks and Solander, etc. Nat.
name, “ Pcka-peki,” Middle Island, Lyall.
Whole plant more or less clothed with loose white wool, except the pedicels and involucres. Sterrns simple or
branched, 2-3 feet higli. Leaves rather stiff, very long and narrow, 2-8 inches long, often much crowded on the
stems, inch 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 tbe 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 tbe tip, with au
obscure ring at the apex.—Found in common with all the preceding both in Australia and Tasmania.

One of tbe largest known genera of plants, scattered over the whole surface of the globe, but rare in tropical
plains and in very cold regions ; it contains upwards of 300 species. The individual species have not wide ranges,
but are extremely variable and are often difficult to define. The majority are herbs, but some form bushes, and a
few are small trees.— Capitula yellow, many-flowered. Florets of tbe circumference female, ligulate, or like those of the
disc ; those of the disc tubular, campanulate above, hermaplirodite, five-cleft ; anthers exserted. Arms of the styles
of the disc-llorets truncated, downy at the tip only ; those of the ligulate florets linear, rounded, blunt, smooth.
Involucre broadly hemispherical or obloug, of one series of long, green, herbaceous scales, usually brown at the tips,
as long as the disc, and with a few much smaUer scales at their base. Beceptacle convex, papUlose. 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 magiiiflcciil species of each from the Middle Island. (Name from senex.
an old man ; iu allusion to the white hairy pappus.)
j a. Herbs {sometimes with shrubby stems) with radical spreading leaves, and one- or many-fimcered scapes.
