involucre cottony, inner shortly radiating; female florets in 1 series; 
pappus-hairs rather slender, clavate-papillose towards the apex, scaberulous

Apparently a rare and local plant. Hooker compares it with the Tasmanian 
Raoulia catipes (Hook. f. Fl. Tasm. i (1860) 206, t. 58), but states that the leaves are 
smaller, the heads not 4 the size, and much more numerous. AR. catipes has been 
selected by Beauverd as the type of his genus Hwartia; and the structure of the 
flower-heads of H. Sinclairvi corresponds with that of HL. catipes in all essential points. 
Helichrysum Fowerakert Cockayne in Trans. N.Z. Inst. xlviii (1916) 196 is a species 
based upon a single specimen collected by Cockayne and Foweraker at Robinson Creek, 
inland Kaikoura Mountains. It has the habit and appearance of Hwartia Sinclasrir 
and the inflorescence of Helichrysum bellidioides, and, as suggested by Cockayne, is 
probably a hybrid between the two plants.

14. HELICHRYSUM Vaill. 227 (S077 
Herbs or small shrubs, very variable in habit, often woolly or tomen- 
tose. Leaves alternate or the lower rarely opposite, quite entire. Heads 
solitary or corymbose, heterogamous and discoid or homogamous through 
the suppression of the female florets. Involucre from cylindrical to broadly 
hemispherical ; bracts in several series, with or without white or coloured 
spreading petal-like scarious tips. Receptacle flat or convex, naked or 
pitted. Female florets exterior, few, sometimes altogether wanting, 
fiiform, minutely 2-3-toothed. Disc-florets hermaphrodite, numerous, 
tubular with a funnel-shaped 5-toothed mouth. Anthers sagittate at the 
base, produced into fine tails. Style-branches of the disc-florets almost 
terete, truncate or subcapitate. Achenes small, terete, 5-angled or com- 
pressed. Pappus-hairs in | series (rarely in several series), free or connate 
below, simple or barbellate or plumose above. 
A very large and heteromorphous genus, probably containing more than 350 species, 
found in most parts of the world, and especially plentiful in South Africa and Australia. 
Tt has been united with Gnaphalium by many authors, but can usually be distinguished 
by the hermaphrodite florets being always much more numerous than the female ones. 
All the New Zealand species are endemic.
