plants. The genus is best distinguished from such Olearias as 0. Colensoi by its herbaceous 
habit and ribbed leaves. 
Heads with long, purple, 3-toothed rays 1 . P. speciosum. 
Heads with very short 2-3-partite rays 2. P. criniferum. 
1. P. speciosum, Hoolc.f. FI. Antarct. i. 31. t. 22, 23. Stem 2-3 ft. 
high ; root thick, fleshy. Leaves villous with bristles intermingled, radical 
oblong, 1 ft. long, 6-8 in. broad, quite entire, ribs 18-20, canline smaller. 
Eaceme leafy, sometimes compound below. Heads 2 in. broad, very hand- 
some, purple.

2. P. criniferum, Hoolc.f. FI. Antarct. i. 32. t. 24, 25. Stem 2-6 ft. 
high, sometimes branched at the base, covered at the base with the curled 
hair-like dry ribs of the old leaves. Radical and lower leaves silky-villous, 
2 ft. long, 1 broad, amplexicaul at the base, broadly oblong, quite entire, 
ribs about 20-40, upper narrow, densely silky. Raceme simple. Heads 
subglobose ; involucral scales ciliate-dentate, glabrous or tomentose.

3. CELMISIA, Cass. 
Perennial Aster-like herbs, with fusiform roots, or creeping branched 
rhizomes. Leaves all radical, rosulate, simple, entire or toothed, most fre- 
quently covered with more or less appressed white or buff tomentum. Scapes 
with linear bracts, 1-headed. — Heads large, rayed. Involucral scales in few 
or many series, linear or subulate, usually pubescent or cottony or glandular, 
often recurved. Receptacle plane or convex, even or deeply alveolate. Florets 
of ray female , in one series, with long spreading or revolute, white or purplish 
ligules ; arms of style with linear obtuse even arms, thickened at the edges : 
of disk hermaphrodite, tubular, 5-toothed, tube often thickened below; 
anthers with very short tails ; arms of style shorter, tipped with long or 
short glandular cones. Pappus of about 2 series of rather few, unequal, rigid, 
scabrid, white or reddish bristles, the outer shorter. Acliene linear, often 
as long as the pappus, angled or terete, rarely compressed, glabrous or silky, 
the hairs usually bifid at the very tip. 
A most beautiful genus, abundant in New Zealand, and, as in all the other large genera of 
these islands, the species are very variable, difficult to discriminate, and intermediate forms 
may be expected between those here described. It is very closely allied in characters but 
not in habit to the large northern genus Erigeron, and the minute obscure tails to the 
anthers is the only diagnostic mark ; three South American Erigerons, indeed, have all the 
habits of Celmisia, they have, however, the a nthers of Erigeron, in which genus Weddell 
has placed them. From Aster, the same characters ef the anthers, and the rarely flattened 
achenes distinguish them. From Olearia and Pleurophyllum, they differ only in habit. 
Two of the New Zealand species, and another are Australian ; the genus is unknown else- 
where. 
A. Leaves more or less toothed or serrate ( often obscurely), white or buff beneath 
( glabrous in a var. of Sinclairii). Involucres generally viscid.. 
Leaves 6-9 x 1^-2 in., acutely serrate, lanceolate 1. C. holosericea. 
Leaves 3-6 x 3 -I 3 in., crenate, narrow linear-oblong 2. C. densiflora.
