8. VITTADINIA A. Rich. \$32- 
Branched perennial herbs or small undershrubs, usually woody at the 
base. Leaves alternate, entire or toothed or lobed. Heads rather small, 
solitary and terminating the branches or forming loose terminal corymbs. 
Involucre hemispherical or campanulate; bracts in few series, imbnicate, 
narrow, acute; margins scarious, Receptacle pitted, without scales. 
Ray-florets all female, numerous, crowded, ligulate. Disc-florets her- 
maphrodite, tubular, dilated upwards, usually 5-lobed. Anthers obtuse 
at the base. Style-branches narrow, somewhat flattened, with subulate 
tips. Achenes usually narrow, compressed, with or without nbs. . Pappus 
copious, of numerous unequal capillary bristles. 
A small genus of 8 or 10 species, found in New Guinea, Australia, Tasmania, New 
Caledonia, and extra-tropical South America. The species from the Sandwich Islands 
formerly included by Asa Gray and other botanists in Vittadinia now constitute the 
endemic genus Z'etramolopium. 
1. V. australis A. Rich. Fl. Nouv. Zel. (1832) 251—A small much- 
branched herb 4-12in. high, hard and woody at the base; branches 
numerous, decumbent or suberect, usually more or less hispid-pubescent 
or glandular, rarely almost glabrous. Leaves }-}1in. long, obovate- 
spathulate to linear-cuneate, entire or 3-5-toothed or -lobed at the tip, 
narrowed into a broad flat petiole, hispid or pubescent. Heads solitary 
on short peduncles terminating the branches; involucral bracts few, in 
2-3 series, linear-subulate, acute, erect, hispid or pubescent. Ray-florets 
in 1 series, usually exceeding the pappus, narrow, white, spreading. 
Disc-florets narrow, slender, longer than the involucre. Achene linear, 
compressed, obtuse at the tip, narrowed to the base, pubescent, usually 
with 5-8 striae on each face. Pappus exceeding the achene.—A. Cunn.

North AND Souts Isuanps: From the Great Barrier Island and Whangarei 
southwards, but local to the north of the East Cape. Sea-level to 3000 ft. No- 
vember—January. 
Also found in Australia and Tasmania, where it runs into numerous varieties, 
some of which differ widely from the type, and may prove to be distinct species. Of 
these var. dissecta (Benth. Fl. Austral. iii (1866) 491) has become naturalized near 
Nelson. It can be distinguished by the leaves being pinnatifid, with the segments 
again lobed, and by the purple ray-florets. Two other closely allied forms (var. 
linearis and var. erecta T. Kirk Students’ Fl. (1899) 295), with linear or linear- 
spathulate leaves 3-14 in. long and purple rays, have established themselves in the 
interior of Otago and elsewhere in the South Island. 
9, HAASTIA Hook. f. 16° & 
Densely or laxly tufted perennial herbs, often forming large rounded 
or amorphous masses in alpine localities; root stout, branched, often 
very long; branches hard and woody, altogether concealed by the per- 
sistent leaves. Heads large, solitary at the tips of the branches, sessile 
and sunk among the uppermost leaves. Involucre hemispherical or 
broadly campanulate; bracts in about 2 series, linear, with scarious 
tips, the inner usually narrower, almost glabrous, the outer broader, 
densely woolly. Receptacle flat, papillose. Outer florets numerous,
