IPOMOPSIS

SCARLET GILIA

Dieter H. Wilken

Annual, perennial herb
Stem generally branched at base
Leaves alternate, simple, gradually smaller upward, entire to pinnately or palmately lobed; lobes generally small-pointed at tip
Inflorescence: clusters, lateral and 1-sided or terminal and open to head-like, rarely solitary and pedicelled in lower axils
Flower: calyx generally bell-shaped, tube and sinuses membranous, lobes generally small-pointed at tip; corolla bell-shaped or salverform, radial or bilateral, white to red or lavender
Seeds slender, angled, slightly winged, white to light brown
Species in genus: 30 species: w North America, se US, s South America
Etymology: (Greek, striking appearance)
Reference: [Grant & Wilken 1988 Bot Gaz 149:443–449]
Perennial species cross-pollinated, annual species generally self-pollinated. Distinguished from Gilia by inflorescence, leaf morphology, chromosome number, flavonoid chemistry.
