Genera In Family: 3 genera, +- 76 species: Americas, Caribbean, Hawaii; some cultivated (Eriodictyon, Wigandia). Toxicity: Dermatitis sometimes caused by contact with glandular hairs (Eriodictyon parryi, Wigandia). Note: Previously treated within Boraginaceae in TJM2 and APG (1998) or as a tribe (Nameae) or subfamily (Namoideae) within Hydrophyllaceae; a distinct lineage from an emended Hydrophyllaceae (Ferguson 1998[1999]; Refulio-Rodríguez & Olmstead 2014).

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.
