site the petioles, or below them, very small, sepals deciduous ; petals, 5, 
narrow; stamens 5, carpels 5-7, stigmas spreading; achenes somewhat 
flattened, smooth, beak slightly recurved, slender. 
Hab.: South Island: Catlin River. D. M. Petrie and T. Kirk. 
Allied to Rs hirtus, Banks and Sol., from which it differs in the procum- 
bent habit, short slender peduncles, and small flowers with few carpels 
The flowers closely resemble those of R. parviflorus, L. 
Rosacea. 
Acana depressa, n. s. 
Stem matted, depressed, much branched, forming dense patches on the 
surface of the ground. Leaves 1-1} inches long, villous below, leaflets in 
8-5 pairs, decreasing in size towards the base of the petiole, ovate or orbi- 
eular, sharply toothed, strigillose above. Head sessile, almost hidden by 
the leaves; calyx 4-angled, villous, angles produced into four flexuous red 
spines, spreading, barbed ; petals 4; achene 1, bony. 
Hab.: South Island: Cardrona Valley ; Lake Hawea, Otago. 
A singular species. The heads are so closely hidden by the leaves that 
they would scarcely be observed except for the bright red, soft, flexuous 
spines, which project in all directions.
