become leafy racemes. Fruit, a small ovoid, shining nut, with eight ribs, smooth or rugose on the surface. — 
Cunningham's Cercodia incana appears to me identical with this plant.

This appears to be the same with a Tasmanian plant called by me G. serpyllifolia, and which, judging from 
the variable form of its leaves, may prove to be GŒ. tenellus, DO. Stems 2-8 inches long, branching from the base, 
often long, slender, filiform, scabrous. Leaves small, 2-3 lines long, sessile, ovate, broadly oblong or rounded, co- 
riaceous, with deeply toothed cartilaginous margins. Flowers sessile, solitary, in the axils of the upper leaves. 
Nuts very small, bright brown, shining, four- to eight-ribbed. E

A very small species, guite smooth everywhere, slender, sparingly leafy, erect or prostrate, simple or 
branched, 8-6 inches high, smelling 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, small, drooping, almost sessile flowers. Fruit very small, shining, turgid, eight-ribbed.— This 
curious little plant is common in Tasmania and South Australia; I have also found it in the Khassya Mountains of 
India, and at 5—8000 feet in the Himalaya Mountains. It does not agree with De Candolle’s description of Gonio- 
carpus tenellus, but entirely with M. Brongniart’s plate, which is unaccompanied by any description. 
Gen. II. MYRIOPHYLLUM, ail. 
Flores uni- v. bi-sexuales. Calycis tubus ovario adnatus, inconspicuus; limbo brevissimo, 4-lobo, v. 0. 
Petala (fl. fcem. 0) 4, concava, membranacea, decidua. Stamina 4—8; filamentis brevibus ; antheris lineari- 
elongatis. Carpella 4, plus minusve arcte coherentia, apice stigmatibus plumosis abrupte terminata. 
Fructus nucumentaceus, 4-coccus; coccis l-locularibus. Semina solitaria, pendula, albumine parco; em- 
bryone axili, tereti; cotyledonibus brevibus; radicula elongata, hilo proxima. 
Water herbs, with long submerged flaccid stems and leaves, the latter capillaceo-multifid, and all whorled 
or entire, alternate, or opposite towards the ends of the branches. Flowers unisexual, rarely bisexual, axillary. Calye- 
tube of the female united to the ovaria; limb minute, four-lobed or absent, of the male four-partite or absent. Petals 
of the fem. absent; in the male four, concave, caducous. Stamens four to eight; anthers long. Carpels 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, 02; embryo terete, with blunt cotyledons, and a long radicle, 
turned towards the hilum.— The genus is found in all latitudes, and the species have very wide ranges. (Name 
from puptos, a myriad, and pudov, a leaf.)
