XXXIX. COMPOSITE. 
[Traversia. 
A remarkable plant, allied to Senecio, but differing remarkably in the rigid pappus, very 
coriaceous iuvolucral scales, and venation of the leaves, which recalls that of the Juan Fer- 
nandez genera, Balbisia and Rolinsonia. 
1. T. baccharoides, Hook.f. Apparently a small shrub, perfectly 
glabrous, somewhat glutinous on the leaves and base of the involucres. 
Branches slender, angled, with raised lines that are decurrent from the leaves. 
Leaves 1^—2 in. long, coriaceous, obovate-laneeolate, serrate, acute, the nerves 
running nearly parallel to the midrib, and anastomosing. Heads on slender, 
rigid pedicels, 1-2 in. long, about in. diam. ; involucral scales green, 
shorter than the florets. 
Middle Island: Upper Avvatere and Wairau valley, alt. 5000 ft., Sinclair ; Discovery 
Peaks, 5500 ft., Travers. 
20. MICROSERXS, Don. 
Glabrous herbs, with milky juice, perennial roots, linear leaves, and naked 
scapes. — Involucre narrow, scales in 1 series, slender, with a few short small 
ones at the base. Receptacle naked, pitted. Florets all ligulate, yellow. 
Pappus of 1 series of rather rigid, flat, brown hairs, broadest at the base, 
produced upwards into fine scabrid points. Achene slender, striate, not 
beaked. 
A genus of only two species, a South American one and the present. 
1. M. Forsteri, 1 look. f. FI. N. Z. i. 151. Very variable in size, from 
2-12 in. Leaves narrow, flaccid, quite entire toothed pinnatifid or irregu- 
larly cut. Scapes glabrous or downy above. Heads in. long ; involucral 
scales rather fleshy ; borders membranous. Pappus pale yellow-brown. — 
FI. Tasman, i. 226. t. 66 ; M. pygmcea, Raoul, not Hook.; Scorzonera sca- 
pigera, Forst. 
Northern and Middle Islands : common from the Thames river, southward, ascend- 
ing to 3000 ft. on the mountains. Also found in Tasmania and Southern Australia. This 
differs from the Chilian species only in the narrower pappus-scales. 
21. CREFIS, Linn. 
Branching or (the New Zealand species) scapigerous herbs, with milky 
juice. — Heads campanulate, bracteate at the base. Involucral scales in 2 or 
3 series, herbaceous, green, outer short, inner longer, often tipped with black. 
Receptacle naked. Florets all ligulate. Pappus of several series of exces- 
sively fine, silky, more or less pilose hairs. Achene linear, not beaked. 
A large genus of the north temperate zone, not found in Tasmania or Australia. 
1. novse-Zelandiae, Hook. /., n. sp. A scapigerous herb, very vari- 
able in stature, 2-12 in. high, glabrous all over, or with the leaves, or scape, 
or involucre, or all, white and tomentose. Root stout, fleshy. Leaves 
spreading, gradually widened upwards into a large, entire, obtuse lobe, or 
linear and pinnatifid to the base, or petioled and lobed along the margin, 
lobes toothed ; sometimes the leaf is pinnatifid to the midrib, with all the 
lobes toothed, and the alternate smaller. Scape slender, naked, glabrous or 
tomentose, and studded with long, black, glandular hairs. Heads |-1-| in.
