Wigandia is a genus of flowering plants within the waterleaf subfamily, Hydrophylloideae. They are found mainly in Central America and South America, though one or two species are found as far north as the United States. Some are grown as ornamental plants and will flourish in most Mediterranean or temperate regions. The genus is named for Johann Wigand (c. 1523–1587), German Lutheran cleric and theologian, and Bishop of Pomesania.[1]
Within the Hydrophylloideae, Wigandia species are unusual in having minute seeds and a high base chromosome number (19); it is also the only neotropical genus in the subfamily.[2]
Some species originally classified in Wigandia are now treated in other genera, e.g. Eriodictyon. There is a group of closely related genera within the Hydrophylloideae subfamily, and it is likely that further taxonomic work will result in additional reclassifications. A recent molecular phylogenetic analysis of the Hydrophylloideae[3] included two Wigandia species (W. caracasana and W. urens), and confirmed that they lay within a clade that includes Eriodictyon, and also the genera Nama and Turricula.
The genus as currently recognized comprises over 20 species, including the following:

Eriodictyon californicum (formerly W. californica)Wigandia es un género de plantas con flores perteneciente a la familia Boraginaceae. Comprende 32 especies descritas, con sólo dos de ellas aceptadas, 12 taxones sin resolver y los demás clasificados como sinónimos.[1]
Son plantas grandes, perennes, sufruticosas a arborescentes, diversamente pelosas (incluyendo pelos urticantes) y frecuentemente glandulosas en toda la planta. Hojas frecuentemente bastante grandes pero variables en tamaño desde 5-60 × 3-42 cm, simples, alternas, cartáceas a coriáceas, ovadas; base cordata a truncada; márgenes irregularmente 2-dentados; ápice obtuso a subagudo. Inflorescencias con pocas a numerosas flores, frecuentemente con apariencia densamente espigada, en panículas o cimas escorpioides, terminales; flores sésiles a subsésiles. Flores con el cáliz persistente, partido casi hasta la base, los lobos subiguales, linear-lanceolados a lanceolados, agudos, acrescentes, híspido-hirsutos a tomentosos y ciliados; corola generalmente más larga que el cáliz, blanco-verdosa, amarilla, o de color lavanda a púrpura, frecuentemente parcialmente pilosa a tomentosa externamente, los lobos redondeados; estambres exertos, en parte adnatos a la base del tubo de la corola, los filamentos pelosos al menos en parte, las anteras linear-oblongas, dorsifijas; ovario súpero, oblongo, peloso, 1-locular, los óvulos numerosos; estilos 2, alargados; estigmas capitado-claviformes, deprimidos. Cápsulas ovado-oblongas, pelosas, loculicidas o septicidas; semillas numerosas, diminutas, reticulado-rugosas, pardas.[2]
El género fue descrito en 1818 por Carl Sigismund Kunth en Nova Genera et Species Plantarum (quarto ed.) 3: 126–127.[2] La especie tipo es: Wigandia caracasana Kunth.
