Inflorescence: raceme, panicle, +- umbel-like or not. Flower: perianth parts 6 in 2 generally petal-like whorls, often showy; stamens 3 or 6, filaments free or +- fused to perianth, anthers attached at base or near middle; ovary superior or +- so, style 1, entire or 3-lobed.

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.
