Has. Northern and Middle Islands; common in dry hilly places, Banks and Solander, etc. Nat. 
name, “ Peka-peki,” Middle Island, Zyall. 
Whole plant more or less clothed with loose white wool, except the pedicels and involucres. Stems simple or 
branched, 2-3 feet high. Leaves rather stiff, very long and narrow, 2-8 inches long, often much crowded on the 
stems, 4-1 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. /nvolucres 
much larger than in any of the former species, nearly 4 inch long, narrow; 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 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 the circumference female, ligulate, or like those of the 
disc; those of the dise tubular, campanulate above, hermaphrodite, five-cleft; anthers exserted. Arms of the styles 
of the disc-florets 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 the Middle Island. (Name from senex, 
an old man; in allusion to the white hairy pappus.) 
§ a. Herbs (sometimes with shrubby stems) with radical spreading leaves, and one- or many-flowered scapes.

Has. Northern and Middle Islands. Foot of Ruahine mountains, Colenso; Nelson, Bidwill; Akaroa 
and Canterbury, Raoul, Lyall. 
Root stout, fusiform, bearing a tuft of spreading, petiolate, radical leaves, 2-4 inches long. Petioles stout, 
woolly, clothed at the base with a thick mass of brown silky wool. Lamina of leaf oblong or rounded, blunt, 
entire, wrinkled, covered above with short, stout, scattered, conical, jointed setze, below with thick wool. Scapes 
about 6 inches high, divided, each branch bearing a large yellow capitulum, pubescent and also covered with 
spreading black glandular hairs, bearing small leaves at the axils. Heads 3-13 inch across, including the broad 
rays. Involucral scales oblong, acuminate, pubescent and glandular. Receptacle pitted, almost alveolate. Achenia 
long, slender. Pappus unequal, scanty, short, white, unusually rigid and scabrid for the genus. Ligule very long,
