Atriplex. | CHENOPODIACEAE. 409 
NortH Jsnanp: Wellington—Sandy shores of Palliser Bay, Colenso/ Sour 
IstaND: Vicinity of Nelson, P. Lawson! Also recorded from Canterbury, but I 
have seen no specimens from thence. 
A common plant in many parts of Australia and Tasmania, and very closely allied 
to the European and African 4. Halimus Linn. 
2. A. patula Linn. Sp. Plant. (1753) 1053.—A very variable erect 
or decumbent or prostrate annual herb 1-2 ft. high, green and smooth, 
or sparingly mealy-white. Leaves petiolate, 1-3in. long, lanceolate to 
broadly triangular-hastate, acute or obtuse, entire or coarsely sinuate- 
‘toothed ; the uppermost often smaller and linear, the lowest sometimes 
opposite. Flowers small, monoecious, in clusters arranged in rather slender 
spikes, often forming narrow terminal panicles; the male and female 
flowers mixed or occasionally some of the females form separate axillary 
clusters. Male perianth small, 5-partite. Fruiting-bracts ovate-rhomboid or 
deltoid, acute, the disc smooth or tubercled ; margins toothed or entire-—

Fl. Austral. v (1870) 173; Cheesem. Man. N.Z. Fl. (1906) 584. 
NortH anpD SoutH Istanps: Not uncommon in brackish-water swamps and 
other places near the sea from the Thames River southwards. December—March. 
Now plentiful in almost all temperate parts of the world, either native or naturalized. 
How far it is indigenous in Australia and New Zealand is now very difficult to determine. 
The broad-leaved form known as var. hastata is the one most generally seen, but the 
more slender var. littoralis is also met with. 
3. A. Buehanani 7. Kirk ex Cheesem. Man. N.Z. Fl. (1906) 584.— 
An excessively branched prostrate herb, forming broad depressed greyish- 
white patches 3-9 in. across; stem woody at the base; branchlets slender, 
wiry, terete. Leaves shortly petiolate or almost sessile, $-4 in. long, oblong 
or oblong-ovate to suborbicular, rounded at the tip, quite entire, both 
surfaces densely clothed with white scurfy tomentum. Flowers minute, 
monoecious. Males in few-flowered clusters in the axils of the upper leaves 
or terminal, sometimes solitary. Perianth densely farinose, 5-partite ; 
segments oblong, obtuse, incurved at the tip. Stamens 5, exserted ; 
filaments fiiform. Females solitary or in clusters of 2-5 in the lower axils, 
occasionally a few females at the base of the male clusters. Fruiting-bracts 
connate into an ovoid or almost urceolate 2-lipped cup. Utricle suborbicular, 
compressed, sunk within the base of the bracts—Chenopodium Buchanani

Var. tenuicaulis Petrie in Trans. N.Z. Inst. xlvii (1915) 54.—Stems slender, erect 
or ascending, sparingly branched, 5-8in. high, farinose above. Leaves few, distant, 
longer and narrower than in the type.
