Higher Taxonomy
Family: HydrophyllaceaeView DescriptionDichotomous Key
Habit: Annual, perennial herb, generally hairy, generally taprooted. Stem: prostrate to erect. Leaf: simple to pinnately compound, basal or cauline, alternate or opposite; stipules 0. Inflorescence: cyme, generally raceme-like and coiled, or flowers 1. Flower: bisexual, generally radial; calyx lobes generally 5, generally fused at base, generally persistent, enlarging in fruit; corolla rotate to cylindric, generally deciduous, lobes generally 5, appendages in pairs on tube between filaments or 0; stamens generally 5, epipetalous, filament base sometimes appendaged, appendages scale-like; ovary generally superior, chambers 1 or 2, placentas 2, parietal, enlarged into chamber, sometimes meeting so ovary appears 2--5-chambered, style 1, style branches 2, stigmas generally head-like.

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.
