branch. Umbels 3— 15-flowered. Pedicels usually exceeding the fruits. In-

SOUTH Island : Canterbury : Rangitata River, Sinclair ! Near the source of the Kowai,

Easily distinguished by the peculiar habit and excessively coriaceous leaves. 



7. A. pallida. G-labrous, flaccid. Rootstock emitting creeping stolons. 

 Leaves crowded at the apex, 4in.— Jin. in diameter, .3-foliolate or rarely 

 3-partite ; leaflets sessile, cuneate or obovate-cuneate, 3— 6-lobed at the tips, 

 sh-ining, pale-green; petioles lin.— 3in. long; stipules lacerate. Peduncles 

 usually shorter than the leaves, bearing a single terminal umbel in the axil of 

 a petioled 3-lobed leaf ; frequently secondary or tertiary umbels are developed 

 in like manner, on very short peduncles. Umbels 4— 12-flowered. Involucral 

 leaves linear, obtuse. Flowers very small ; calyx-teeth minute. Pedicels 

 exceeding the fruit. Fruits slightly narrowed above, obtusely 4-angled; ribs 5.

8. A. nitens, Petrie in Trans. N.Z.I, xxv. (1892) 370. Rhizomes very 

 slender, creeping, matted. Leaves few, solitary, 3-foliolate or 3-partite ; leaflets 

 yig-iii.— Jin. long, shortly petiolulate or sessile, ovate-cuneate below, entire or 

 obscurely 1— 3-toothed, obtuse or subacute, perfectly glabrous ; petioles ^in.— 

 l^in. long; stipules broadly ovate, acute. Peduncles axillary, on short 

 1— 3-leaved scapes, solitary or 2 or 3 together, very short. Flowers solitary 

 or in 2— 3-flowered umbels. Involucral leaves 3, narrow-linear. Calyx-teeth 

 minute, acute. Fruits equalling the pedicels, shortly tetragonous, x^in. long,

SOUTH Island: Nelson: shores of Lake Guyon, &c., Amiiri (1875), T. K. Canterbury: 

 Broken River basin, Enys and Kirk (1876). Otago: Clinton River and Te Anau Lake, Petrie! 

 700ft. to 3,000ft. Dec, Jan. 



Easily recognised by its diminutive size, matted rhizomes, and small fruits with rounded 

 angles. It resembles depauperated states of Hydrocotyle muscosa. 



9. A. trifoliolata, Benth. and Hook. I.e. A very slender usually gla- 

 brous species. Stems filiform, creeping and rooting at the nodes. Leaves 

 2-5, fascicled at the nodes, very membranous, 3-foliolate, rarely 3-partite ; 

 leaflets shortly petiolate or sessile, obovate-cuneate, obcuneate or flabellate, 

 unequally crenate or 3— 4-lobed or toothed, apiculate, rarely laciniate, glabrous 

 or with scattered hairs above or below; petioles lin.— 4in. long; stipules 

 small ciliate or laciniate. Peduncles iin.— lin. long. Umbels 1—4, 2—8- 

 flowered. Involucral leaves free. Calyx -lobes acute. Fruits tetragonous, 

 shortly rounded at both ends; mericarps distinctly 5-ribbed. Pedicels shorter
