woolly ; inner narrow, scarious and hyaline at the tips, none rayed or white, all spreading after the florets have fallen

2. Helichrysum Zeontopodium, Hook. fil.; radice perenni uni-tri-cipite, caule brevi robusto dense 
molliter lanuginoso, foliis radicalibus plurimis rosulatis dense congestis lineari-oblongis subacutis sessilibus 
utrinque sericeis, caulinis paucis oblongis, capitulis congestis, bracteis patentibus densissime lanuginosis 
involucratis, involucri squamis omnibus erectis. Tas. XXXVII. B. 
Haz. Northern Island. Ruahine mountains and Mount Hikurangi, Colenso. 
This very remarkable plant is so similar to the genus Leontopodiwm of the European 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, and 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, 4-3 inch 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. Involueres 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 florets 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.—

Capitulum multiflorum, heterogamum, discoideum ; flosculis marginalibus 9 , multi- v. pauci-seriatis, 
tenuissimis, 2—4-dentatis; disci $, 4-5-dentatis. Receptaculum nudum, subpapillosum. Involucerum 
cylindraceum ; squamis anguste linearibus, l-seriatis. Sžy/i rami cono superati. Achenia oblonga, striata, 
obtusa v. apice attenuata, pilosa v. scabrida. Pappus pluriserialis, tenuissimus, scaberulus.— Herbze erecta, 
simplices v. ramosa, glaberrime v. lanate. 
A genus of tall, smooth or woolly, simple or branched, herbaceous plants, bearing corymbs of many exceed- 
ingly narrow heads, which have no ligulate florets. —Zmvolucre 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 Erechtites 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. 
(Name used by Dioscorides for some species of Senecio.)
