calyx, being each furnished with 
an awn-like spine at the apex). D. C. prod. 3. p. 372. Lobes o

at the apex, 2 inner ones small, and nearly unarmed. Stigmas 2, 
sessile.

lobes of calyx unequal, 3 outer ones the largest, and furnished 
with a long mucrone each : 2 inner ones smaller, and nearly awn- 
less. Flowers crowded in the axils of the leaves. Y.G. Na- 
tive of Brazil, in the province of St. Catharine, in sand by the 
sea side, where it is called by the inhabitants Rosetta. Probably 
a species of Pentac@ na.

1 P. lanugindsa (Poir. suppl. 4. p. 302.) is probably a 
species of Gomphréna. 
2 P. Bengalénsis (Roem. et Schultes, syst. 5. p. 521. but not

6 P. linearifdlia is now Polycarpæ'a linearifélia. 
Cult. All the species of this genus are well adapted for orna- 
menting rock-work, from their dwarf stature, and generally 
trailing habit. Most of them, however, grow best in small pots 
in sand and loam, filling the pots half way with sherds ; and 
they are easily increased by dividing the plants at the root, or 
by cuttings under a hand-glass, or by seeds. The seeds of the 
annual species only require to be sown in the open border or on 
rock-work. Some of the species are marked green-house and 
frame ; these require to be protected from frost in winter.

wanting. Stamens 5, opposite the lobes of the calyx, and inserted 
in their base ; 2 of which are sterile, obcordate, and flat: and 3
