1. S. aisiaeetene in Engl. Bot. Jahr. xl (1908) 578. — Very 
slender, with much of the habit and appearance of a Hydrocotyle. Stems 
filiform, branched, creeping and rooting at the nodes, 2-12 in. long. Leaves. 
2-6 at each node, membranous, glabrous or with a few scattered hairs, 
3-foliolate ; leaflets 1 in. long, shortly stalked or sessile, obovate-cuneate 
to flabellate, irregularly 2-6-lobed or -toothed ; lobes obtuse or apiculate ; 
petioles slender, 14in. long; stipules small, ciliate. Peduncles much 
shorter than the leaves, usually 2-3 springing from the same point. Umbels 
2-8-flowered ; involucral bracts subulate, ciliate or laciniate. Fruits obtusely 
tetragonous, longer than their pedicels; carpels rounded at the back, 
5-ribbed.—Pozoa trifoliolata Hook. f. Fl. Nov. Zel. i (1853) 85, t. 18;

Foveaux Strait. Sea-level to 4000 ft. November—February. 
A distinct and graceful little species, at once recognized by the long slender 
creeping stems; the trifoliolate leaves with the leaflets evidently stalked, and very 
irregularly lobed; and by the peduncles of the umbels much shorter than the leaves. 
Drude’s name of Azorella Hookeri was given on account of the specific name of 
trifoliolata being preoccupied in Azorella; but that disqualification does not apply to- 
Schizeilema. 
2. S. nites eBomin m Engl. Bot. Jahr. xl (1908) 579.—Small, slender, 
perfectly glabrous, smooth and shining, densely matted. Rhizomes creep- 
ing, much branched and interlaced. Leaves few, minute, 4-4in. diam..,. 
3-foholate or 3-partite ; leaflets sessile or shortly stalked, oblong-ovatg 
to linear-obovate, obtuse or acute, entire or obscurely 2—3-toothed, rather 
thin, perfectly glabrous; petioles slender, 4-14in. long. Peduncles as 
long or longer than the leaves, usually bearing a single terminal 2—3-flowered 
umbel with 1 or 2 3-lobed leaves below it, but often a secondary umbel. 
is developed from the base of the primary one; involucral leaves linear, 
acute. Fruits minute, ;;in. long, obtusely tetragonous, rather turgid, 
about equalling the pedicels ; capsules obscurely 5-ribbed.—Azorella nitens 
Petrie in Trans. N.Z, Inst. xxv (1893) 270; ZT. Kirk Students’ Fl. (1899). 
193; Cheesem. Man. N.Z. Fl. (1906) 202.

A very distinct little plant, in habit somewhat agreeing with small states of 
Hydrocotyle tripartita. 
3. S. hydrocotylotdse et syn in Lingl. Bot. Jahr. xl (1908) 581.—. 
Perfectly glabrous, stout, often densely matted. Root long and woody. 
Stems creeping and rooting at the nodes and putting up tufts of leaves, 
the runners sometimes 6in. long or more. Leaves numerous, crowded, 
¢-gin. diam., orbicular or orbicular-reniform, very thick and coriaceous, 
3-5-foliolate or -partite ; leaflets sessile, sometimes overlapping, broadly
