Simpsonanthus jonesii
SIMPSON'S POPCORNFLOWER, MOJAVE POPCORNFLOWER


Higher Taxonomy
Family: BoraginaceaeView DescriptionDichotomous Key
Common Name: BORAGE FAMILY
Habit: Annual, perennial herb, or shrub, often bristly or sharp-hairy. Stem: prostrate-decumbent to erect. Leaf: basal and/or cauline, simple, generally alternate, sometimes opposite, especially at base. Inflorescence: cymes, arranged singly or in groups of 2--5, generally coiled in flower, generally elongating in fruit. Flower: bisexual, generally radial; sepals 5, free or fused at least at base; corolla 5-lobed, salverform, funnel-shaped, rotate, or bell-shaped, appendages (often called "fornices") 0 or 5 at top of tube, when present often differentially pigmented, alternate stamens; stamens epipetalous; ovary superior, 4-lobed, style 1, entire or minutely 2-lobed (2-branched). Fruit: nutlets 1--4, when > 1, all similar (often called "homomorphic") or 1 or 2 dissimilar in size and/or shape from the others (often called "heteromorphic"), free (fused), smooth to roughened, prickly or bristly or not.
Genera In Family: +- 90 genera, +- 1600--1700 species: mostly temperate, especially western North America, Mediterranean; some cultivated (Borago, Echium, Myosotis, Symphytum). Toxicity: Many genera may be TOXIC from pyrrolizidine alkaloids or accumulated nitrates. Note: Sometimes still treated in broader sense of TJM2 (e.g., APG IV 2016 Bot J Linn Soc 181:1--20), but recent evidence (Luebert et al. 2016) supports segregation, for our flora, of the families Ehretiaceae, Heliotropiaceae, Hydrophyllaceae, Lennoaceae, and Namaceae.

Genus: SimpsonanthusView Description 



Etymology: (Greek: Simpson's flower, for Michael G. Simpson, CA botanist, 1953) Note: More closely related to Amsinckia and Amsinckiopsis than to Plagiobothrys (where previously included) based on molecular phylogenetic studies (Guilliams et al. 2020).

Simpsonanthus jonesii (A. Gray) Guilliams, Hasenstab & B.G. Baldwin
NATIVE
Habit: Annual, few- to several-branched throughout, taprooted. Stem: ascending to erect, to 5 dm, sharp-spreading-bristly. Leaf: cauline, alternate, sessile, oblong to elliptic, sometimes lanceolate on distal stem, 2--10 cm, generally rough-bristly with bulbous-based hairs, sometimes soft-bristly and/or short-fine-hairy. Inflorescence: raceme- or spike-like cymes, coiled in bud, generally elongate in fruit; bracts proximal; pedicel 0--1 mm. Flower: calyx lobes free to base, narrowly lanceolate to +- linear, soft-bristly, margins often ciliate, 4--9 mm in fruit; corolla +- funnel-shaped, white, limb 1--3 mm diam, appendages minute, light yellow, fading to white. Fruit: nutlets 3--4, 2--3 mm, triangular-ovate, abaxially cobblestone-like, coarse tubercles 0, abaxial and lateral ridges +- ill-defined or 0, transverse ridges and grooves 0, adaxially keeled; attachment scar at middle of adaxial keel crest, narrowly lanceolate to narrowly triangular, irregular, length +- 1/2 of nutlet.
Ecology: Sandy, gravelly, rocky washes and slopes, creosote-bush scrub, pinyon/juniper woodland; Elevation: 90--1900 m. Bioregional Distribution: s SNH, SNE, D; Distribution Outside California: to southern Utah, western Arizona, Mexico. Flowering Time: (Jan)Mar--May(Jun) Note: Resembles Amsinckia tessellata var. tessellata (in which corolla is yellow).
Synonyms: Plagiobothrys jonesii A. Gray

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.
