araneosis, floribus radii tubo elongato laxe piloso, ligula lata brevi trifida, achenio elongato profunde 
costato. 
Var. a; tomento laxiore fulvo, foliis majoribus, paniculis elongatis. Tas. XXIX. 
Var. 8; tomento appresso argenteo, panicula abbreviata. 
Has. Northern and Middle Islands. Var. a. Mount Hikurangi and east coast, Colenso. Var. 8. 
Dusky Bay, Lyall. 
A stout, branching, large shrub, with thick branches and branchlets, more or less woolly and spreading leaves, 
crowded towards the ends of the latter. Leaves very thick, rigid and coriaceous, 14-4 inches long, broadly ob- 
ovate, acute, tapered into a short stout petiole; margin cut irregularly into short and sharp unequal teeth; upper 
surface smooth or rough, with reticulated sunk veins; lower covered densely with wool, which is loose and yellow 
in var. a, appressed and silvery in var. 8. Panicles erect, with five to seven pedunculate heads of flowers, and ovate 
concave bracts, more or less silky and woolly all over. Heads of flowers 3-1 inch across. Flowers of the ray with 
a short, broad, trifid ligula, and long hairy tube. Pappus dirty yellow-brown, 3—4 lines long. Achenia as long 
as the pappus, ribbed, silky.—PLATE XXIX. Fig. 1, receptacle; 2, floret of ray; 3, floret of dise :—all magnified. 
5. Olearia Zyallii, Hook. fil. ; subarborea, ramis ramulisque validis crassis lignosis foliis subtus pani- 
culisque lana molli alba appressa dense indutis, foliis amplis breve petiolatis elliptico-ovatis obovatisve 
acutis obtuse crenato-dentatis, paniculis polycephalis, capitulis pedunculatis breviter radiatis, bracteis sub- 
foliaceis oblongis dorso pedunculis pedicellis involucrisgue densissime lanatis, acheniis costatis dense seri- 
ceis, pappi setis sordide fulvis, floribus radii 0? disci tubo dense sericeo. Eurybia Lyallu, 7%. Antaret.

Has. Middle Island, Milford Sound, ete., Zyall. 
A very magnificent species, found originally in 1841 at Lord Auckland’s Group by Dr. Lyall, but not in 
flower. In the ‘Flora Antarctica’ I assumed it to be the same species as the foregoing, and described them as one 
plant, under the name of Zurybia Lyallü. Better specimens of O. Colensoi, together with others from Dr. Lyall both 
of O. Oolensoi and Lyallii, from the Middle Island, prove them to be different plants. The present differs from the 
former in its much larger and broader leaves, with blunt crenatures at the margin; as also in apparently wanting 
the ray flowers. The tube of the corolla is densely silky. 
Gen. IL. EURYBIA, Cass. 
Capitulum pauci- v. multiflorum, heterogamum, radiatum. Involucrum oblongum ; squamis oblongis, 
imbricatis, exterioribus brevioribus. Zeceptaculum convexum, parvum, alveolatum, nudum v. subsetosum. 
FI. radii 1-seriati, ligulati, feminei: disci tubulosi, 5-dentati, hermaphroditi. Antheris breviter aristatis. 
Achenium glabrum v. pubescens, costatum. Pappus 1-seriatus ; setis scabris, subeequilongis.— Frutices v. 
arbores habitu varia; capitulis parvis. 
Trees or shrubs, variable in habit, with generally tomentose under surface of the leaves, branches, and pedicels ; 
and eorymbs or panicles of small heads of white-rayed flowers, with a yellow dise. Heads few- or many-flowered ; 
the outer flowers rayed, female, in one series; the inner tubular, five-cleft, hermaphrodite. Receptacle convex, con- 
tracted, pitted, naked or with a few bristles. nvolucre oblong, of many rigid, scarious, blunt, imbricating scales, 
the outer shortest. Achenia smooth, glandular, or pubescent. Pappus of one series of scabrid bristles, nearly 
equal in length. —A. very large New Holland and Tasmanian genus, unknown elsewhere, except in New Zealand. 
The Z. argophylla forms one of the largest forest-trees of Tasmania. (Name, that of the Mother of the Stars in 
Greek Mythology; given in allusion to the numerous star-like flowers.)
