---|---|
Palomar monkeyflower |
|
Habit | Annuals, taprooted. |
Stems | erect, simple or branched from basal nodes, 4–20 cm, minutely puberulent. |
Leaves | cauline, basal not persistent; petiole 0 mm; blade 1-veined or palmately 3-veined (in broader ones), lanceolate to ovate, 3–20 × 1–6 mm, base attenuate, margins entire, sometimes toothed, apex acute, surfaces minutely puberulent. |
Flowers | herkogamous, 1–36, from distal or medial to distal nodes. |
Styles | distally pubescent. |
Corollas | pink to purple, abaxial limb with 2 yellow palate ridges, bilaterally symmetric, weakly bilabiate; tube-throat funnelform, (3–)6–10 mm, exserted beyond calyx margin; limb expanded 3–14 mm, lobes notched, adaxial limb glabrous, sometimes sparsely bearded. |
Fruiting pedicels | ascending to spreading horizontally, (2–)12–60(–68) mm. |
Fruiting calyces | sometimes red-dotted, campanulate, 3–6 mm, margins distinctly toothed or lobed, minutely puberulent, ribs weak, lobes pronounced, erect, margins glabrous. |
Capsules | included, 5–8 mm. |
Stigmas | distinctly shorter than corolla tube. |

Erythranthe diffusa |

Phenology | Flowering Apr–Jun. |

Discussion | Erythranthe diffusa has been included previously in E. palmeri but can be distinguished morphologically by glabrous margins on the calyx and pubescence on the distal end of the style. It occurs in Orange, Riverside, and San Diego counties as well as close to the California border in Baja California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
