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 ).

CHASMANTHE

Perennial; corms ± round, with thin, fibrous covering
Stem generally unbranched
Inflorescence: generally spike, terminal; flowers each subtended by 2 ± equal, entire bracts
Flower asymmetric; perianth funnel-shaped, tube curved, basal part ± cylindric, generally > bracts, lobes unequal, upper longest, ± curved, parallel to lateral 2, lowest 3 < upper, reflexed; stamens arched under upper perianth lobe, exserted; style parallel to stamens, exserted, branches each entire
Seeds many, colored
Species in genus: ± 9 species: s Africa, several ornamental
Etymology: (Greek: gaping flower)

Introduced

C. floribunda (Salisb.) N.E. Br.


Stem generally < 1 m
Leaf 20–65 cm, 2.5–5 cm wide, sometimes wider on 1 side of midrib
Inflorescence: flowers 20–30, 2-ranked
Flower: perianth < 4 cm, scarlet and yellow
Ecology: Uncommon. Disturbed urban areas
Elevation: < 50 m.
Bioregional distribution: Central Coast, San Francisco Bay Area
Distribution outside California: native to s Africa
Long mistaken as C. aethiopica (L.) N.E. Br.; plants sometime persist from garden waste.

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).
