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].
Genera In Family: +- 15 genera, 230 species: +- worldwide, many habitats; some cultivated as ornamental (e.g., Mimulus, Mazus). Formerly included in Scrophulariaceae. Note: Family description by David J. Keil.

Genus: MimulusView DescriptionDichotomous Key

Habit: 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.
Species In Genus: +- 100 species: North America, Chile, eastern Asia, southern Africa, New Zealand, Australia. Etymology: (Latin: little mime or comic actor, from face-like corolla of some species) Note: Limb width measured between most distant points across corolla face.

Mimulus bolanderi A. Gray
Habit: Annual 2--90 cm, generally densely hairy. Leaf: 5--60 mm, oblanceolate to ovate, lowest leaves glabrous, upper densely hairy. Flower: pedicel 2--5 mm; calyx 7--27 mm, widely ribbed, swollen especially in fruit, densely hairy, lobes generally +- spreading in fruit, unequal, 1--9 mm, acute to acuminate; corolla persistent, magenta, throat floor white, tube-throat 10--30 mm, throat floor with small magenta hairs; placentas parietal. Fruit: 8--20 mm. Chromosomes: 2n=16.
Ecology: Granite outcrops, burns, openings in chaparral, disturbed areas; Elevation: generally 300--1700 m. Bioregional Distribution: KR, NCoR, SN (common c SNF), CW, WTR. Flowering Time: Apr--Jul Note: Very small plants much like Mimulus rattanii.
