Var. tu a Cheesem. n. var. — Branchlets stout, almost matching those of 
H. coralloides. EL “TAArs 2° 
Var. tomentosum Cheesem. Man. N.Z. Fl. (1906) 343.—Leaves oblong, subacute, 
almost altogether concealed by fulvous tomentum. Heads not seen. Probably a 
distinct species. 
Soutn Isntanp: Not uncommon in mountain districts from Nelson to Foveaux 
Strait. 2000-4500 ft. December—January. Var. tuberculata: Wairau Gorge, 
Nelson, alt. 3000 ft., 7. F. C., Cockayne ! Var. acuta : Mountains behind the Hanmer 
Plains, T. F. C., C. H. Christensen / Var. tumida: Near Cape Saunders, Otago, 
Cockayne ! Var. tomentosum: Mount Dobson, 7. F. C., alt. 5000 ft. 
An exceedingly variable plant. Dr. Cockayne has kindly forwarded a series 
of some 5 or 6 supposed varieties, 3 of which I have briefly characterized above. The 
remainder require more study with larger suites of specimens than have hitherto been 
obtained.

11. H. coralloides , Benth. and Hook. f. Gen. Plant. u (1873) 311.— 
A short stout much-branched shrub 4-48 in. high, hard and woody below; 
branches spreading, cylindrical, 4in. diam., densely tomentose between 
the leaves, which resemble tubercles on their surface. Leaves closely 
appressed to the branch, imbricated in many series, $-}1n. long, oblong, 
obtuse, very thick and coriaceous towards the tip, membranous below, 
inner face concave and densely clothed with long woolly tomentum, back 
convex or obscurely keeled, glabrous and polished. Heads 4-4in. diam., 
terminal, solitary, sunk amongst the uppermost leaves ; involucral bracts 
in about 3 series, linear-oblong, rigid and cartilaginous at the base; tips 
thinner, scarious, often recurved. Florets numerous; female few, in one 
series. Achene pubescent. Pappus-hairs few, stout, slightly thickened 
above.—T. Kirk Students’ Fl. (1899) 312; Cheesem. Man. N.Z. Fl. (1906) 
343; Cockayne Veg. N.Z. (1921) tt. 53, 54. Ozothamnus coralloides 
Hook. f. Fl. Nov. Zel. 11 (1855) 332; Handb. N.Z. Fl. (1864) 147.

Awatere, Sinclair! Cockayne! Medway Creek, 7. Kirk! Palmer River, Cockayne. 
Nelson—Western slopes of Mount Percival, 7. F. C. 3000-5000 ft. 
A very remarkable plant. In its ordinary state the leaves resemble glossy tubercles 
closely set along the branches; but those of the juvenile plant are altogether different, 
and are open and spreading. Under suitable conditions, these juvenile leaves may 
be occasionally seen on “reversion shoots” on adult plants, just as is the case in 
certain species of Veronica. | 
15. CASSINIA R. Br. 1&7 
Shrubs or very rarely herbs. Leaves alternate, entire. Heads small, 
numerous, in terminal corymbs or panicles, discoid, homogamous in most 
of the species, but usually heterogamous in those found in New Zealand. 
Involucre oblong or ovoid; bracts in several series, imbricate, scarious ; 
the inner with short white radiating tips. Receptacle narrow, with scarious 
chaffy scales among the florets. Florets few, in the majority of the species 
all hermaphrodite, tubular, 5-toothed ; but in the New Zealand species 1 
or 2 of the outer ones are female, filiform, minutely toothed. Anthers 
sagittate at the base, usually produced into slender tails. Style-branches 
of the hermaphrodite florets terete, truncate. Achenes small, angled ar 
almost terete. Pappus-hairs in 1] series, slender, free or connate at the base. 
A small genus of about 20 species, confined to Australia, New: Zealand, and South 
Africa. The New Zealand species are all endemic, and with 1 or 2 from South Africa 
constitute the subgenus Rhynea, characterized by the inner involucral bracts having 
short white radiating tips, and by the heads usually having 1 or 2 female florets. The 
Species are very closely allied, and are by no means easy to discriminate.
