G«n. Ch. Male, Cal. none. Cor. none. Stam. Fila- 

 ment one, fimple, elongated, ereft ; anther ovate-oblong, 

 ereft. 



Female, clofe to the male. Cal. Perianth of one leaf, 

 inferior, hollow, fwelling, oblique, with two or three teeth. 

 Cor. none. Pijl. Germens from four to eight, ftalked, 

 oblong, converging ; ftyles as many, fimple, rather fpread- 

 *ng ; ftigmas ovate, peltate, flat, fpreading outwards. 

 Perk. none. Seeds as many as the germens, naked, 

 ftalked, oblong, comprefled, a little incurved, beaked with 

 the permanent ftyles, tuberculated at the back, with a 

 fimple coriaceous coat. 



Obf. Schreber fpeaks of fome folitary, difperfed, male 

 flowers, furniihed with a fingle-leaved calyx, whofe orifice 

 is oblique, acute at the pofterior part, and entire. He fol- 

 lows Gaertner in confidering the coat of each feed as a cap- 

 fule ; but the latter allows there is fcarcely any internal 

 coat, or integument, to the kernel, and the outer one is 

 deftitute of valves ; fo that although the ftyle be perma- 

 nent, we rather follow Linn^us than other authors ; and we 

 conceive that if the exiftence of a naked feed be admitted 

 in any inftance, it muft be in the prefent ; there being only 

 a fimple covering to the embr^'o, which is indifpenfable. 



Eff. Ch. Male, Calyx none. Corolla none. Filament 

 elongated, eredl. Anther oblong. 



Female, Calyx of one leaf. Corolla none. Germens 

 four, or more. Stigmas peltate. Seeds ftalked, naked.

— Anther of four cells. Stigmas entire Native of ponds, 



ditches, and rivulets, in Italy, as well as other parts of 

 Europe, from Sweden to Conftantinople, flowering in fum- 

 mer. It is found alfo in Virginia, near the fweet fprings, 

 according to Clayton and Purfli. The root is annual. 

 Stem flender, floating, branched, round, leafy, and fmooth, 

 with the habit of a Potamogeton. Leaves hnear, gran"y, 

 feflile, narrow, acute, and entire, two or three inches long. 

 BroRea membranous, tubular, axillary, including a pair of 

 green Jloivers, one male, the other female. Anther tawny. 

 Seeds blackifli when ripe, rugged or toothed at the back.

 of two cells. Stigmas toothed. — Found in the neighbour- 

 hood of Florence, with the foregoing, as well as in mountain 

 pools in the adjacent country. Rather fmaller than the firft 

 fpecies, with flnorter leaves ; but moit eflentially different in 

 havmg only two cells to the anther, and remarkably toothed 

 Jligmas. The feeds alfo are tuberculated all over, not 

 merely toothed at the back, or keel. 



Loureiro has a Z. tuberoja, Fl. Cochinch. 543, to which 

 he attributes " ovate-oblong fingle-feeded berries." It 

 grows in the waters of Cochinchina, and has tuberous 

 perennial roots, radical, fword-fliaped leaves, fpiked^o'Zffrx, 

 the calyx of the female in fix deep fegments. We agree 

 with M. Poiret that it would be too hazardous to admit this 

 fpecies without examination. Loureiro had probably never 

 feen a real ZanntcheUia.

ZANONIA, in Botany, bears that name in memory of

 Zanom, fuperintendant of the public garden at Bologna. 

 Hepubhftied in 1675 a folio volume, in Italian, entitled 

 IJiona Botamca, with 80 plates, of new or rare plants, ac- 

 companied by defcriptions. Monti gave an enlarged edition 

 of this work, in Latin, in 1742. Zanoni died in 1682, 

 aged 67. Plumier, who fpeaks of him as a learned and cri- 

 tical inveftigator of the plants of the ancients, pubhflied a 

 Zanonta, in his Nov. Gen. 38. t. 38, which Linnxus has re-

Gen. Ch. Male, Cal. Perianth of three ovate fpreading 

 leaves, fliorter than the coroUa. Cor. of one petal, in five 

 deep, fpreading, pointed, inflexed, equal fegments. Stam. 

 Filaments five, fpreading, the length of the calyx ; anthers 

 fimple. 



Female, on a feparate plant, Cal. Perianth as in the male ; 

 feated on the germen, deciduous. Cor. as in the male. 

 Pift. Germen oblong-clubftiaped, inferior ; ftyles three, 

 fpreading, conical, reflexed, permanent ; ftigmas divided, 

 crifped. Peric. Berry large, elongated, abrupt ; tapering 

 at the bafe ; encompailed near the top with a crifped future, 

 of three cells. Seeds two in each cell, rounded-oblong, flat, 

 in the centre of a lanceolate fcale, or wing.

 PI. 1457. Willd. n. I. Poiret n. i. (« Penar-valli ; Rheede 

 Hort. Mai. V. 8. t. 49, male; t. 47, 48, female.") — 

 Native of Malabar and Ceylon. A ftranger in the gardens 

 of Europe, nor do we recolleft having ever feen a fpecimen, 

 Linnaeus having, in this inftance, confided entirely in the 

 Hortus Malabaricus, which was very rarely his cuft:om. 

 The herbaceous branching_y?fm appears to chmb by means 

 of fimple, fpiral, axiUar)' tendrils. Leaves alternate, ftalked, 

 ovate-oblong, acute, entire, fmooth. Flo'wers in lax droop- 

 ing clujlers, which in the male appear to be fomewhat com- 

 pound. Fruit oblong, abrupt, obfcurely triangular, with 

 the flavour of a cucumber according to Rheede. There 

 oan be little doubt of this genus belonging to the gourd 

 tribe, whether it anfwers to all the charafters which authors 

 have been pleafed to apply to that tribe or not. The open- 

 ing of the fruit betrays fome analogy to Momordica 

 operculata.
