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

YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).
