nanthe species, Spreng. 
Lin. syst. Pentdndria, Diginia. Margin of calyx bluntly 
5-toothed. Petals oval, flat, entire. Styles short. Fruit orbi- 
cular, biscutate; mericarps compressed from the back, joined with 
the narrow commissure, and therefore constituting 2 parallel 
disks; dorsal rib filiform, 2 lateral ones hidden, and the middle 
ones girding the disk ; vittee wanting ; furrows between the ribs 
broad and flat.—Stemless glabrous herbs, natives of Chili and 
Brazil. Leaves all radical, petiolate, ternate: leaflets wedge- 
shaped, toothed or cut at the apex; the lateral segments some- 
times 2-parted. Scapes longer than the leaves. Umbels com- 
pound, 6-8-rayed; peduncles much longer than the involucrum, 
which is 4-5-leaved. Umbellules 3-flowered, middle flower fer- 
tile, lateral 2 male; hence the generic name. Flowers white. 
The fruit is like that of Mulinum, and the inflorescence that of 
Petagnia.

that of Carum denudatum or C. Bulbocdstanum. Umbels com-

Lin. syst. Pentandria, Diginia. Limb of calyx _5-toothed, 
Petals elliptic, entire, acutish, with a straight apex. Fruit ovate, 
much compressed at the raphe, flat, and compressed from the back 
on both sides; meticarps flat, without any vittæ ; ribs 5, very 
slender, equal, 3 intermediate ones on the back, and the 2 lateral 
ones seated in the commissure, which is flat. Seed flat.—A 
South American branched erect herb, glabrous in every part, 
except on the petioles, which are ciliated along the sheaths, and 
ornamented with a collar of hairs under the origin of the limb. 
Leaves cordate, toothed, acute. Umbels rather compound, pro- 
liferous. Involucra composed of many leaves. Flowers white 
on long pedicels.

Native of South America, in Trinidad, and the Spanish Main, as 
well as of Peru. Hydrocétyle spananthe, Willd. spec. 1. p. 
1363. Phelldndrium ciliatum, Willd. herb. Perhaps the Peru- 
vian plant is the same as that from the Spanish Main, but it 18 
much smaller and hardly panicled. 
Panicled Spananthe. Fl. July, Aug. Clt. 1795. Pl. 1 to 2 ft. 
Cult. The seeds of this plant should be raised on a hot-bed, 
and when the plants are of sufficient size plant them ito 
separate pots, and then place them in the stove, where they will 
flower and seed; and some may be planted out in the open 
ground. Not worth cultivating except in botanic gardens.

and xaproc, karpos, a fruit). Hook. and Arn. in bot. misc. 3.

k Lin. syst. Pentándria, Digýnia. Margin of calyx 5-toothed : 
teeth subulate, minute, hardly permanent. Petals ovate, pies 
cave, entire. Styles 2, divaricate, short. Fruit roundish-ovate ; 
mericarps compressed on the back, flat, wingless, constituting 
2 parallel disks; commissure very narrow; ribs 5, filiform, 
very slender, hidden in the substance of the pericarp, ‘os 
dorsal, 2 lateral ones near the raphe, 2 middle ones bei e 
angles, without any vittæ; carpophore entire. Seed less t 
the cavity of the fruit.—Herb annual, erectish, hoary from a X 
late hairs, dichotomously branched. Root slender, aes 
Leaves petiolate, reniform-roundish, somewhat 5-lobed ; l0 
equal, ovate, obtuse, quite entire or deeply lobed ; lower age 
alternate: superior ones opposite. Peduncles axillary and er 
minal, about equal in length to the petioles. Umbels simp “ 
8-6-flowered. Teeth of calyx pilose, almost emulating rei a 
of hairs. Fruit nearly twice the length of their pedicels, whic 
area line long. This genus comes near to Spandnthe. of

the Cordillera of Chili. The ridges or ribs of the fruit are 0 y 
to be seen on a transverse section of the fruit, because ip ee 
sunk in a thin substance of the pericarp. The middle p 3 
do not expand into wings as in Mulinum, and some other 
genera.
