6. ACTINOTUS Labill. 
Annual or perennial herbs, erect and branching or low and densely 
tufted. Leaves toothed, lobed or ternately divided. Umbels simple, 
with an involucre of spreading bracts. Calyx-limb 5-toothed, rarely 
inconspicuous. Petals 5, unguiculate or spathulate or wanting. Ovary 
l-celled, 1-ovuled; styles 2, often united at the base. Fruit ovate, of a 
single carpel, compressed from front to back ; ribs 5, often obscure. 
A small genus of about 10 species, confined to Australia and New Zealand. It 
is remarkable for the 1-celled ovary and single carpel of the fruit.

1. A. suffoeata/Rodway Tasm. Fl. (1903) 65.—Small, densely tufted. 
Stems creeping, interlaced and matted, forming flat compact patches. 
Branches villous or shaggy with soft white hairs. Leaves ;;—¢ in. long, 
oblong or oblong-spathulate, narrowed into a long sheathing petiole, quite 
entire, coriaceous and fleshy, glandular at the apex, glabrous or with a 
pencil of hairs at the tip. Peduncle }-? in. long, usually villous with soft 
spreading hairs, naked or with a single bract towards the top. Involucral 
bracts usually 5, broadly ovate or almost rounded, obtuse. Flowers 4-5.

Hooker’s plate in the ‘‘ Flora of Tasmania ’’ admirably represents the New Zealand 
plant, and as his specific name of “suffocata’’ is unquestionably entitled to priority

7. OREOMYRRHIS Endl. 1G 34, 
Perennial herbs, tufted or more rarely diffusely branched, glabrous 
pubescent or villous. Leaves pinnately divided or decompound. Umbels 
simple, solitary on a scape or peduncle ; involucral bracts numerous, ovate 
or lanceolate. Calyx-teeth obsolete. Petals oblong, acute, with a short 
incurved tip. Fruit oblong or linear-oblong, usually tapering to the apex, 
slightly compressed laterally; carpels subterete, with 5 equal obtuse ribs, 
the 2 lateral ones close to the commissure. Vittae 1 in each furrow and 
2 on the commissural face. Seed nearly terete, but grooved on the com- 
missural side. 
A genus of 6 or 7 species. Six of these are natives of America, from Mexico to 
the Falkland Islands, one of them extending to Australia and New Zealand. Another 
species has recently been found in New Guinea,
