Gen. I. HALORAGIS, Font, [including Goniocarpus, Koen., and Cercodia, Murr.)
Flores nni-bisexuales. Calycis tubus teres, angulatus v. alatus ; limbns 4<-lobus, lobis persistentibus.
Petala 4, cóncava, decidua. Stamina 4 -8 ; antlieris longitudinaliter debiscentibus. Stigmata 4, Simplicia
v. plumosa. Fructus nucumentaceus, inclelbscens, 2—4-locularis. Semina solitaria, pendula; embryone
axi albuminis carnosi, tereti ; radicula hilo próxima.
Erect, prostrate, or creeping, opposite or alternate-leaved herbs, smooth or scabrid. F/o«>ers hermaphi’odite or
bisexual, axillary towards the ends of the branches, small, green or purplish, fascicled or racemose, generally
shortly pedicellate, drooping. Calyx-tube adnate to the ovary, rounded, angled, or winged; limb fonr-lobed.
Petals four, deciduous, concave. Stamens four to eight ; anthers two-celled, often bursting laterally. Stigmas four,
sessile, simple or plumose. Fruit, a small hard nut, with a fleshy or coriaceous coat, which is rounded, angled, or
-ninged; indéhiscent, two- to four-cebed; cells with one pendulous albuminous seed; embryo terete, with two short
cotyledons, and radicle next to the hilum.—This genus is most frequent in the Southern Temperate zone of the Old
World, especially in Australasia ; and is also found iu aU parts of India. Juan Fernandez is its only South American
habitat. (Name from áXy, the sea, aud pa^, a grape-stone, from the form of the fruit of the original species, w’hich
grows near the sea.)

This plant is a native of Juan Fernandez, whence all the specimens I have seen are perfectly smooth, bke many
of the New Zealand ones, whilst others are more or less scabrid on the angles of the stem, leaves, and fruit. Stem
herbaceous or procumbent, with erect four-angled branches. Leaves opposite, rarely alternate (|—l i inch), shortly
petiolate, ovate, ovate-lanceolate or oblong, blunt or acuminate, sharply and deeply serrated. Flowers in axillary
whorls or fascicles along the branchlets, which become leafy; racemes small, green. Anthers large. Fruit, an
angular nut, 1 line long, covered with a coriaceous green coat, which is more or less produced at the angles into
wings ; the sides smooth or rough.—This is a very variable plant in size, foliage, and smooth or rough surface ; but
easily recognized by the little four-winged or four-angled fruit, crowned at the narrow upper end by four ovate,
acute, conniving calyx-lobes.

H ab. Northern Island; abundant in dry places, Banks and Solander, Cunningham, etc.
A very common Austraban and Tasmanian plant, scabrid with short, white, stiff hairs over every part. Stems suberect
or diffuse, 3-8 inches long. Leaves inch) opposite, sessile, rounded, oblong or ovate, subacute, rigid, harsh,
deeply serrate, with cartilaginous margius. Flowers in the axils of tbe smab upper leaves of the branches, which
become leafy racemes. Fruit, a smab ovoid, shining nut, -with eight ribs, smooth or rugose on the surface.—
Cunningham’s Cercodia incana appears to me identical with this plant.

H ab. Northern Island; in dry and wet places, not unfrequent, Cunningham, etc.
This appears to be the same with a Tasmanian plant cabed by me <?. serpyllifolia, and which, judging from
the variable form of its leaves, may prove to be G. tenellus, DC. Stems 2-8 inches long, branching from the base,
often long, slender, filiform, scabrous. Leaves smab, 2-3 lines long, sessile, ovate, broadly oblong or rounded, coriaceous,
with deeply toothed cartilaginous margins. Flowers sessÜe, solitary, in the axils of the upper leaves.
Nuts very small, bright brown, shining, four- to eight-ribbed.

nitidis 8-costatis. (A.ÍQntWMS,Brongn.in Buperrey,Voy. An BC.? G. ó.túoá.ox\\.s, A. Cunn. Prodr.
H ab. Northern Island; in boggy places, Cunningham, etc. Nat. name, “ Piri Piri," Cunn.
A veiy smab species, quite smooth everywhere, slender, sparingly leafy, erect or prostrate, simple or
branched, 3-6 inches high, smelbng I presume of lemons, from Cunningham’s name, but I never perceived this
when fresh. Leaves few, opposite, 2-3 lines long, orbicular, remotely and deeply toothed. Racemes leafless, of few
scattered, bracteolate, smab, drooping, almost sessile flowers. Fruit very smab, shining, turgid, eight-ribbed.—This
curious little plant is common in Tasmania and South Austraba; I have also found it in the Khassya Mountains of
India, aud at 5-8000 feet in the Himalaya Mountains. It does not agree with De Candobe’s description of Goniocarpus
tenellus, but entirely with M. Brougniai't’s plate, which is unaccompanied by any description.

Water herbs, with long submerged flaccid stems and leaves, the latter capillaceo-multifid, and ab whorled
or entire, alternate, or opposite towards the ends of the branches. Flowers unisexual, rarely bisexual, axibaiy. Calyx-
tube of the female united to the ovaria; bmb minute, four-lobed or absent, of the male four-partite or absent. Petals
of the fern, absent; in the male four, concave, caducous. /S¿aMm« four to eight; anthers long. four, more or
less adherent, with four thick, usually plumose stigmas ; each carpel forms a minute nut, with a fleshy covering, one-
celled, with one pendulous seed; albumen scanty, 0 ?; embryo terete, with blunt cotyledons, and a long radicle,
turned towards the hilum.—The genus is found in ab latitudes, and the species have very wide ranges. (Name
from fivpios, a myriad, and <^uXXoi>, a leaf.)
