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

Perennial; rhizomes compact
Stems single or tufted, generally ± flat and winged or rounded, sometimes with leaf-bearing nodes well above basal leaves, each with 1 or more flower-branches
Leaf narrow, grass-like
Inflorescence: flowers in umbel-like clusters; bracts 2, equal in length or not, margins translucent
Flower ephemeral; perianth reddish purple, bluish, violet, yellow, rarely white, parts ± alike, but outer generally wider; filaments ± completely free to ± completely fused

|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).|
