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 
d-ribbed.—Kirk, Students’ Fl. 193.

700-3000 ft. December-January. 
A very distinct little plant, in habit somewhat agreeing with small forms of 
Hydrocotyle tripartita. 
9. A. trifoliolata, Benth. and Hook. f. l.c.—Very slender, with 
much of the habit and appearance of a Hydrocotyle. Stems fili- 
form, branched, creeping and rooting at the nodes, 2-12in. long. 
Leaves 2-6 at each node, membranous, glabrous or with a few 
scattered hairs, 3-foliolate; leaflets 4-}in. long, shortly stalked 
or sessile, obovate-cuneate to flabellate, irregularly 2—6-lobed or 
-toothed ; lobes obtuse or apiculate; petioles slender, 1-4 in. 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.—Kirk, Students’ Fl. 193. Pozoa trifoliolata, Hook.

3. ERYNGIUM, Linn. 
Perennial herbs. Leaves usually rigid and coriaceous, spinous- 
toothed, entire lobed or dissected. Flowers sessile in dense heads, 
with a bracteole under each flower, and a whorl of rigid often 
spinous-pointed bracts at the base of the head. Calyx-tube clothed 
with hyaline scales; teeth rigid, acute. Petals narrow, erect, 
deeply notched, with a long inflected point. Fruit ovoid or 
obovoid, scarcely compressed, covered with hyaline scales or tu- 
bercles; carpels semi-terete, primary ridges obscure, secondary 
Wanting ; vittez inconspicuous or absent. 
A large genus of over 150 species, spread through most temperate and sub- 
tropical regions, but most plentiful in South America and western Asia. The 
single species found in New Zealand extends to Australia as well. 
1. B. vesiculosum, Lab. Nov. Holl. Pl. i. 73, t. 98.—A harsh 
and rigid spinous herb 2-9 in. high, with tufted radical leaves and 
prostrate stems much resembling stolons but not rooting. Radical 
leaves crowded, rosulate, 3-6 in. long, lanceolate or oblanceolate or 
spathulate-lanceolate, deeply toothed or almost pinnatifid, the tect!.
