Common Name: TRUMPET FLOWER
Stem: hairy or glandular. Leaf: alternate, simple, entire to generally pinnate-lobed, linear to ovate [fan-shaped]; basal short-petioled; cauline sessile. Inflorescence: heads or clusters, terminal, or flowers 1--3 in axils. Flower: calyx lobes connected by narrow membrane forming a pitcher-like projection at sinus, enlarging, not rupturing in fruit; corolla salverform to funnel-shaped. Fruit: ovate to elliptic, explosively dehiscent, valves reflexed on dehiscence. Seed: 1(2--3) per chamber, oblong, generally gelatinous when wet, brown. Chromosomes: 2n=16.

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.
