There are two species of this curious Httle geuus, one Tasmaman (A. Tasmanica, MSS.), the otlier New Zealand.
The latter fonns a slender, prostrate, deHcate, membranous herb, 4 -8 inches long, pubescent on the stems, petioles,
and pedicels, leaves alternate, ivith subulate stipules and slender petioles as long as the blade ( i inch), which
IS rounded and coarsely bluntly toothed. Plowers monoecious. axUlary, Males in the upper axUs, two together at the
apex of a slender peduncle as long as the petiole. Perianth concave, almost bell-shaped, obscurely two-Hpped,
pUose. Stamen soMtaiy. Pemak sohtary, or two to three in the axUs of the lower leaves ; bracteolæ very smaU or
absent. Perianth compressed, flagon-shaped, having an inflated tube and very smaU mouth, through which the filiform
pubescent stigma protrudes, N a t crustaceous, compressed, brown, smooth, enclosed iu the perianth. (Name
from the original species inhabiting Australia.)

A small genus (of which, however, very many species have been made on very insufficient grounds) of weedy
plants, found over all the warm and temperate parts of the globe. Tbe New Zealaud species abounds in Australia
and North and South America (where it is caUed P. Ploridana), and in some parts of Europe, under the name of
P.Lusitanka. I t is very nearly alUed to. and perhaps only a variety of, the origmal Hmoyiew P . officinalis oi
Linnæus, with fewer flowers.— A very weak, trading (rarely erect and stiff), pubescent or glabrous herb. Stems
8 -12 inches long. Leaves membranous, alternate, exstipulate, petiolate, ovate, blunt, quite entire, 4 -1 4 inches
long. Phwers polygamous, pUose, inconspicuous, green, clustered in the axils of the leaves, surroimded by a
two- to four-leaved involucre, composed of connate bracteolæ. Involucres one- to three-flowered. Male flowers
with a fonr-leaved perianth and four stamens ; with a tubular or urceolate four-cleft perianth. Achenium
turgid, with a small capitate sessüe stigma. (Named from parks, a wall; in allusion to the species frequentin»- old
walls.) “

The only New Zealand species is a succulent, prostrate or subereet, hoary, watery herb, with a curved, ascending,
thick, fleshy stem, 1 -2 feet high, branched at the base. Leaves 4 -1 0 inches long, alternate, sessile, elongate,
lanceolate or obovate-lanceolate, acuminate, curved ; base auriculate, half-clasping the stem ou one side; margins
deeply toothed, puberulous, rugose. Stipules deciduous, membranous, lanceolate. Receptacles discoid, monmcious.
Male capitula, i inch broad, rather fleshy, surrounded by imbricating broad connate pilose or glabrous leaflets, axillary,
soUtarj' or binate, sessile or shortly pedunculate. Mowers small, pedicellate, hidden among the large membranou¡
bracts. Reriantli four-parted. Stamens four. Female capitula much smaller, more pubescent. Bracteæ small,
narrow. Flowers minute, nearly sessile ; perianth none, or of one to four narrow linear hairy pieces. Ovaiy ovate,
compressed, with a sessile capitate stigma. Achenium inflated, crustaceous, white mottled with brown. Seed erect,
with a coriaceous testa. (Name from eXarrjp, elastic, and o-TT]ga>v, a stamen.)

An immense genus, whose species abound in Tropical regions and the Temperate climates of the Northern hemisphere,
but are comparatively rare in the Southern. The only New Zealand oue is a herb, with acrid milky juice ; also
found in Norfolk Island. Everywhere quite smooth, often glaucous. Stems tufted, stout, simple, erect, 1 -2 feet
high, leafy above. Leaves spreading, alternate, narrow linear-oblong or broadly obovate, subacute, 2 -3 inches long,
yellow when dry ; floral ones short, broad. Mowers without any perianth, numerous, enclosed in involucres resembling
a periauth, mixed with hairy filaments and flat imperfect male flowers. Involucre bell-shaped, 4 inch across, fleshy^
having four to five purple flat binate glands a t the mouth. Male flowers numerous, included, each consisting of a
single stamen, mounted on a pedicel, appearing like a jointed filament (the joint indicates the place where a
perianth is produced in some species). Anthers didymous. Female flower exserted, hanging over the side of the
involucre, pedicellate, the pedicel jointed below the ovarmm, which is three-lobed, three-celled, with a trifid style
(its arms bifid), and one pendulous ovule iu each cell. Capsides of three cocci, separating from a central axis,
splitting down the back and exposing a single albuminous pendulous seed, with a hard grey testa. Cotyledons large,
flat. (Named from Euphorhus, a physician of Mauritania, who brought tbe plant into use.)

The New Zealand Pepper is a small tree, 12-20 feet high, or sometimes a rambling shrub, with a very aromatic
smell ; it has been used for Tea, aud for the cure of toothache ; it is found also iu Norfolk Islaud, aud belongs
to a siibgeuus (Macropiper) including the very nearly allied P. latifolium of the Peejee and South Sea Islands. The
wood is of very curious structure. Stems zigzag, jointed, quite smooth, glabrous. Leaves petiolate, 2 -3 inches long,
