Plagiobothrys verrucosus
FORGET-ME-NOT POPCORNFLOWER

Higher Taxonomy
Family: BoraginaceaeView DescriptionDichotomous Key

Common Name: BORAGE or WATERLEAF FAMILY
Habit: Annual to shrub or small tree, or non-green root parasite, often bristly or sharp-hairy. Stem: prostrate to erect. Leaf: basal and/or cauline, generally simple, generally alternate. Inflorescence: generally cymes, or panicle-, raceme-, head-, or spike-like, generally coiled in flower (often described as scorpioid), generally elongating in fruit, or flowers 1--2 per axil. Flower: bisexual, generally radial; sepals (4)5(10), fused at least at base, or free; corolla (4)5(10)-lobed, salverform, funnel-shaped, rotate, or bell-shaped, generally without scales at tube base, with 0 or 5 appendages at tube top, alternate stamens; stamens epipetalous; ovary generally superior, entire to 4-lobed, style 1(2), entire or 2-lobed or -branched. Fruit: valvate or circumscissile capsule or nutlets 1--4, free (fused), smooth to roughened, prickly or bristly or not.
Genera In Family: +- 120 genera, +- 2300 species: tropics, temperate, especially western North America, Mediterranean; some cultivated (Borago, Heliotropium, Echium, Myosotis, Nemophila, Phacelia, Symphytum, Wigandia). Toxicity: Many genera may be TOXIC from pyrrolizidine alkaloids or accumulated nitrates. Note: Recently treated to include Hydrophyllaceae, Lennoaceae. Wigandia urens added, as naturalized.

Genus: PlagiobothrysView DescriptionDichotomous Key

Common Name: POPCORNFLOWER
Habit: Annual (perennial herb), generally strigose to spreading-hairy; fibrous- to taprooted, staining red dye present or not. Stem: branched at base or above, < 5 dm. Leaf: cauline or basal and cauline, 0.5--10 cm, generally smaller tipward, linear to oblanceolate. Inflorescence: raceme- or spike-like cymes, coiled in bud, generally elongate in fruit; bracts 0--many. Flower: calyx lobes fused below middle, 2--10 mm in fruit; corolla rotate to funnel-shaped or cylindric, white or white with yellow area, tube generally +- yellow inside, limb 1--12 mm diam, appendages prominent to minute, white to yellow. Fruit: nutlets generally 4, +- ovate (triangular to +- lanceolate), rarely on narrow stalk or short peg, variously roughened, abaxially generally with central ridge, lateral ridges, cross-ribs, generally tubercled, occasionally prickly or bristly; adaxially keeled above attachment scar, scar on side generally near middle to base, sometimes on bottom or oblique (on angle between side and bottom), generally raised.
Species In Genus: +- 65 species: temperate western North America, western South America, northeastern Asia, Australia. Etymology: (Greek: sideways pit, from position of nutlet attachment scar) Note: Nutlet characters in key generally best for 3 nutlets farthest from stem; yellow on corolla changes to white after pollination.
Unabridged Note: Fully mature nutlets needed for identification; in many species nutlet closest to stem often more firmly attached, larger, differently textured, and with completely different attachment scar than other 3; nutlet characters used in key focus on 3 more loosely attached nutlets. Intergradation common in some species groups; reticulate speciation in genus; sect. Allocarya often treated as separate genus; many species need study. Corolla size can diminish markedly during flower period. Yellow corolla appendages and, if present, contrasting yellow corolla centers, change to white after successful pollination.

Plagiobothrys verrucosus (Phil.) I.M. Johnst.
NATIVE
Habit: Annual, +- red, staining, hairs stiff, spreading. Stem: erect, 0.5--2 dm. Leaf: basal in rosette, 1--3 cm; cauline alternate, ovate. Inflorescence: bracts throughout. Flower: calyx 1.5--2 mm, hairs dense, appressed to ascending, straight; corolla limb 1.5--3 mm diam, stained pink, appendages pale yellow. Fruit: nutlet +- 1.5 mm, ovate, brown, +- flat; abaxial ridge narrow, lateral ridges 0, cross-ribs 0, interspaces 0, surface with irregular papillae, tubercles, occasionally low wrinkles; scar near middle, +- round. Chromosomes: 2n=24.
Ecology: Open chaparral, gravelly soil, +- fire follower; Elevation: 700--850 m. Bioregional Distribution: se SnFrB (Mount Hamilton Range); Distribution Outside California: southern South America. Flowering Time: Mar--May
Synonyms: Plagiobothrys myosotoides (Lehm.) Brand, misappl.; Plagiobothrys myosotoides subsp. verrucosus (Phil.) N. Horn, ined.
Unabridged Note: Assignment of California material to this taxon based on Horn's dissertation, 2000, in which Horn used a name that was never published, Plagiobothrys myosotoides (Lehm.) Brand subsp. verrucosus (Phil.) N. Horn ined. Seldom collected. Perhaps most closely related to, confused with Plagiobothrys uncinatus.
