BARTONIA ORNATA.
BARTONIA.
Icosandria Monogyma, Linn. Loaseas, Juss.
GENERIC CHARACTER.
Calioc superior, 5-cleft, persistent. Corolla of 10 petals. Capsule cylindric-oblong,
1-celled, summit flat, valvular: valvulse 3 to 7. Receptacular placentae 3 to 7,
parietal. Seeds numerous, compressed, arranged horizontally in a double
series.
Herbaceous ; leaves alternate, pinnatifid, asperate j flowers large, terminal and solitary,
vespertine, (or expanding towards sun-set,) not deciduous or marces-
cent after closing, but re-opening at the usual time for several days in succession,
when closed involute in a cone; small valves of the capsule variable
in number, but corresponding with the placentae, and the spiral stria-
tures of the stigma; in the germ there exists the rudiments of a columnar
receptacle. The whole plant turns blackish in drying—on the slightest
wound it also exsudes a resinous sap which instantly blackens in the air.
Pubescence compoundly barbed and tenacious, as appears to be more or
less the case in the whole order of the L oasejE. Nutt.
SPECIFIC CHARACTER.
Leaves lanceolate, interruptedly pinnatifid; segments sub-acute; base of the capsule
foliose ; valves 5 to 7 ; seeds nearly without margin. Nutt.
