and Taupo southwards. Soutu IsuaAnpD: Var. viridis: Mountains of Nelson, 
Marlborough and Canterbury, from Mount Arthur to the Rakaia Valley.

Mr. Kirk has described the South Island plant as a distinct species under 
the name of S. viridis. It is somewhat larger in all its parts, but differs in no 
essential character, and is far better regarded as a variety only. Specimens of 
S. Bidwillii collected at the foot of Ruapehu by the Rey. F. H. Spencer almost 
match others gathered in the South Island by myself. 
30. S. geminatus, 7. Kirk, Students’ Fl. 350.—A small spreading 
shrub 1-4 ft. high; perfectly glabrous in all its parts, but the young 
branchlets, leaves, and involucres glutinous; branches slender, 
angled, grooved. Leaves 14-3in. long, 4-lin. broad, obovate- 
lanceolate or obovate-spathulate, acute or subacute, gradually 
narrowed to a sessile and decurrent base, serrate, subcoriaceous ; 
veins thin, subflabellate. Corymbs terminal, lax, leafy at the base ; 
peduncles slender, usually forked, with sparse linear bracts above. - 
Heads few, 4-4in. diam., discoid and homogamous; involucral 
bracts about 8, in 1 series, shorter than the florets, linear-oblong, 
obtuse, coriaceous, with broad membranous ciliolate margins. Re- 
ceptacle flat, alveolate. Florets 12-15, all tubular and hermaphro- 
dite ; limb campanulate, deeply 5-lobed. Stamens exserted; an- 
thers not tailed. Achenes linear-oblong or linear-obovoid, narrowed 
at both ends, grooved, glabrous. Pappus-hairs in 1 series, rigid, 
scabrid. — Traversia baccharoides, Hook. f. Handb. N.Z. Fl. 164;

SoutH Isntanp: Mountains of Nelson, Marlborough, and Canterbury; not 
uncommon from Mount Arthur to the Upper Waimakariri. 1500-4500 ft. 
January—February. 
Avery remarkable species, with a more rigid pappus than is usual in Senecvo, 
and in other respects resembling the Juan Fernandez genera Balbisia and 
Robinsonia. Sir J. D. Hooker created the genus Tvraversia for its reception, 
but in the ‘‘ Genera Plantarum ”’ it was reduced to Senecio. 
22. MICROSERIS, Don. 
Annual or perennial glabrous herbs. Leaves chiefly radical, 
entire or toothed or pinnatifid. Scapes long, leafless, single-headed. 
Heads homogamous. Involucre oblong or cylindric; bracts in 
about 2 series, with a few short imbricate ones below. Recep- 
tacle flat, without scales. Florets all ligulate, yellow. Achenes 
narrow, attenuate at the base, cylindrical, ribbed. Pappus of few 
or several linear flat scales tapering into simple or plumose bristles. 
A genus of 16 or 18 species, all western North American except one from 
Chili and another from Australia and New Zealand.
