IRIDACEAE

IRIS FAMILY

Elizabeth McClintock, except as specified

Perennial, bulbed, cormed, or rhizomed
Stem generally erect
Leaves generally basal (a few cauline), 2-ranked, ± linear, generally grass-like, generally sharply folded along midrib; bases overlapping, sheathing
Inflorescence: spike, raceme, panicle, ± terminal, or flowers solitary; bracts ± like leaf bases, sheathing
Flower generally bisexual, generally radial; hypanthium fused to ovary; perianth parts generally fused into tube above ovary, generally petal-like, in 2 series of 3, outer (sepals) generally ± like inner (petals); stamens 3, generally attached to sepals, filaments fused below into a tube or not; ovary inferior, 3-chambered, placentas generally axile, style 1, each of 3 branches entire or 2-branched or -lobed, petal-like or not, with stigma on under surface instead of at tip
Fruit: capsule, loculicidal
Seeds few–many
Genera in family: 80 genera, ± 1500 species: worldwide, especially Africa; many cultivated (e.g., Iris, Gladiolus, Crocus, Freesia ).

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).
