This is a veiy distinct species, and may at aU times be recognized from G. iumliicratum and G. viryatum by
the broad involucres. wMch bave more unmerous fiorets and paler broader scales ; also by there being very few and
short bracteæ below the heads, or more generally none. The var. y has tall leafy branched stems, a foot high, and
very narrow le.ives, resembling G. involucratum in habit and appearance very closely; but the usual state of this
plant is a tufted herb, a span high, with nmnerous radical petiolate leaves, and simple, sparingly leafy, woolly stems.
Badical leaves 1-3 inches long, linear-oblong or spathulate, sharp or apiculate, smooth or sparingly woolly above,
densely wooRy below, or covered witb appressed silvery tomentum; cmiline leaves narrower, sharp. Capitula
clustered into rounded terminal or axillary dense masses, 4-À inch diameter, pale yellow-brown, shining, with one
or two generally short leafy bracteæ at the base. Involucres 2-3 lines long, broadly oblong or campanulate,
spreading after the florets bave fallen away, and exposing the rather broad many-flowered receptacle.—This is also
a Tasmanian and New Holland plant. In the form of the involucres it resembles O. luteo-athum, but the scales
are less numerous, and the densely-packed inflorescence not presenting the characters of a corymb will at once dis-
tinguish it.
Gen. XVI. HELICHETSUM, LC.
Omnia Gnaplalii, sed flosculi radii ? , 1-seriales.
The New Zealand species of this genus are to be distinguished from Baoulia by the broad receptacle, and from
Gnaphalium by the female marginal florets forming but one row. In the Cape of Good Hope, and Australia and
Tasmania, there are veiy numerous and often extremely handsome species of Helichrysum, and a few are found in
Europe and elsewhere in the Northern Hemisphere. There is much difference of habit amongst them, some having
broad, white, rayed, involucral scales,- like the first section of New Zealand Gnaphalia ; others having narrow
involucres, with erect scales, as in the two species to be described here, (Name a Greek one, supposed to have
been applied to a South European species of this genus.)

This very remarkable plant is so similar to the genus leontopodium of the Em-opean Alps and Himalayan
mountains that it requires some care to discriminate it ; the styles of the disc-flowers are, however, always more or
less bifid, generally deeply, aud its technical characters are hence those of Helichrysum. Root perennial, simple or
branched at the top, bearing one or several short branches, densely clothed with numerous spreading leaves ; and
simple stems 2-3 inches high. Radical leaves closely imbricating, spreading, focb long, sessile, linear-oblong,
thick and coriaceous, rather blunt, silky on both sides. Stem densely woolly, bearing several short silky leaves, and
a terminal mass of eight to ten sessile capitula, surrounded by a spreading general involucre, formed of ten to twelve
or more thickly woolly, linear, blunt leaves. Involucres shortly pedicellate, oblong, campanulate, of one series of
linear, acuminate, scarious scales, woolly at the back. Florets of the circumference in one series, narrow, tubular,
four- to five-cleft ; arms of the styles long, subacute. Disc fiords very numerous ; arms of the styles shorter, equal
or unequal, truncated. Pappus of one row of rather broad bristles, scabrous towards the tips. Achenia hairy.—

A genus of tall, smooth or woolly, simple or branched, herbaceous plants, bearing corymbs of many exceedingly
narrow lieads, which have no ligulate florets. Involucre cylindrical ; scales very long, narrow, erect, in one
series, with a few short ones at the base. Receptacle narrow, papillose. Florets of the circumference in one or
many series, extremely slender, female ; those of the disc broader, hermaphrodite. Arms of the styles tipped with short
hairy cones. Achenia oblong, striated, hairy or smooth. Pappus of numerous, very slender, rough hairs, in many
series.—The species of Frechiites abound in Australia and Tasmania; a few are found in South America, and as far
north as the Southern United States. All the New Zealand species are also natives of Tasmania and Australia.
