Common Name: MUSTARD FAMILY Habit: Annual to shrub; sap pungent, watery. Leaf: generally simple, alternate; generally both basal, cauline; stipules 0. Inflorescence: generally raceme, generally not bracted. Flower: bisexual, generally radial; sepals 4, generally free; petals (0)4, forming a cross, generally white or yellow to purple; stamens generally 6 (2 or 4), 4 long, 2 short (3 pairs of unequal length); ovary 1, superior, generally 2-chambered with septum connecting 2 parietal placentas; style 1, stigma entire or 2-lobed. Fruit: capsule, generally 2-valved, "silique" (length >= 3 × width) or "silicle" (length < 3 × width), dehiscent by 2 valves or indehiscent, cylindric or flat parallel or perpendicular to septum, segmented or not. Seed: 1--many, in 1 or 2 rows per chamber, winged or wingless; embryo strongly curved. Genera In Family: +- 330 genera, 3780 species: worldwide, especially temperate. Note: Highest diversity in Mediterranean area, mountains of southwestern Asia, adjacent central Asia, western North America; some Brassica species are oil or vegetable crops; Arabidopsis thaliana used in experimental molecular biology; many species are ornamentals, weeds.

Common Name: LACEPOD, FRINGEPOD Habit: Annual; hairs 0 or simple. Leaf: simple, sessile, entire, dentate, or pinnately lobed; middle, distal cauline clasping, lobed or not. Inflorescence: open (dense). Flower: sepals ascending, base not sac-like; petals +- >= sepals, white or +- purple-tinged, not clawed; fertile anthers yellow or generally purple (flowers occasionally with whitish or yellowish infertile anthers). Fruit: indehiscent, pendent, elliptic to ovate or round, unsegmented, over-seed (i.e., excluding wing) generally plano-convex; septum 0; wing generally not incurved toward over-seed flat side, entire, wavy-margined, crenate, perforated, or divided into spoon-shaped lobes, rays (radiating veins) present or not, generally +- indistinct; stigma entire. Seed: 1, elliptic to round, wingless. Etymology: (Greek: fringe fruit) eFlora Treatment Author: Ihsan A. Al-Shehbaz & Thomas J. Rosatti Reference: Revised taxonomy based on Alexander et al.

Thysanocarpus laciniatus Nutt.
NATIVE Habit: Plant generally not branched from base, generally glaucous, glabrous (with sparse, rough, stiff hairs near base). Stem: 1--6 dm. Leaf: generally greenish or basal occasionally purplish; basal 2--6(9) cm, oblanceolate to elliptic, subentire, wavy-dentate, or pinnately lobed; cauline linear to narrowly elliptic, bases wedge-shaped, +- lobed or not, +- not clasping. Inflorescence: raceme open. Flower: fertile anthers purple, rarely some flowers with whitish or yellowish infertile anthers. Fruit: 3--5 mm wide, obovate to +- round, greenish, hairs 0.05--0.4 mm, club-shaped, or generally 0; wing flat or +- incurved toward over-seed convex side, entire to deeply crenate, rays 0 or 0.2--0.5 mm wide, +- indistinct; proximal pedicels recurved in a continuous arc, 2.5--6(8) mm. Ecology: Oak woodland, rocky ridges, slopes, chaparral, washes; Elevation: 100--1800 m. Bioregional Distribution: NCoRI, s SNF, Teh, ScV (Sutter Buttes), SnFrB, SCoR, SW, SNE, D; Distribution Outside California: western Arizona, Baja California. Flowering Time: Mar--May Note: Highly variable, probably hybridizes with Thysanocarpus curvipes, resembles the latter when cauline leaf bases lobed.

(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
