PHRYMACEAE LOPSEED FAMILY

David M. Thompson

Annual to shrub. Stem: ×-section generally round. Leaf: opposite, simple, entire or toothed; stipules 0. Inflorescence: spike, raceme, or panicle, bracted, or flowers 1–2 in axils. Flower: bisexual; calyx radial or ± bilateral, tube long, generally ribbed, lobes 5; corolla generally bilateral, generally 2-lipped, upper [1]2-lobed, lower 3-lobed; stamens 4 in 2 pairs, epipetalous, included or exserted; pistil 1, ovary superior, chambers 1–2, placentas parietal or axile, style 1, stigma lobes 2, flat, folding together when touched. Fruit: generally capsule, generally ellipsoid, loculicidal [indehiscent, 1-seeded].
± 15 genera, 230 species: ± worldwide, many habitats; some cultivated as ornamental (e.g., Mimulus, Mazus). Formerly included in Scrophulariaceae. [Beardsley & Olmstead 2002 Amer J Bot 89:1093–1102] Family description by David J. Keil. —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.

MIMULUS MONKEYFLOWER
Glabrous to hairy. Stem: generally erect. Leaf: opposite, generally ± sessile, generally toothed or entire, generally green or ± red. Inflorescence: raceme, bracted, or flowers generally 2 per axil. Flower: occasionally cleistogamous; calyx generally green, lobes 5, generally << tube, generally unequal; corolla generally deciduous, white to red, maroon, purple, gold, or yellow, lower lip base occasionally swollen, ± closing mouth, tube-throat floor generally with 2 longitudinal folds; anther sacs spreading; placentas 2, axile or parietal; stigma lobes generally flat, generally included. Fruit: generally ovoid to fusiform, generally upcurved if elongate, generally ± fragile, loculicidal near tip (hard, indehiscent), chambers 1–2. Seed: many, generally < 1 mm, ovoid, ± yellow to dark brown.
± 100 species: North America, Chile, eastern Asia, southern Africa, New Zealand, Australia. (Latin: little mime or comic actor, from face-like corolla of some species) [Thompson 2005 Syst Bot Monogr 75:1–213] Limb width measured between most distant points across corolla face.
