Hosackia

Hosackia is a genus of flowering plants in the family Fabaceae (legumes). It is native to western North America, from British Columbia in Canada to Mexico.^[1]

Taxonomy

Hosackia belongs to a group of species traditionally placed in the tribe Loteae of the subfamily Faboideae. The taxonomy of this group is complex, and its division into genera has varied considerably. Many species of Hosackia were formerly placed in a broadly defined genus Lotus. A molecular phylogenetic study in 2000 based on nuclear ribosomal ITS sequences confirmed the view that the "New World" (American) and "Old World" (African and Eurasian) species of Lotus did not belong in the same genus. When narrowly circumscribed, Hosackia was monophyletic.^[2][3] New World species at one time placed in Hosackia have been transferred to Acmispon, Ottleya and Syrmatium.^[3]

Species

References

Hosackia est un genre de plantes dicotylédones de la famille des Fabaceae, sous-famille des Faboideae, originaire d'Amérique du Nord, qui comprend une quinzaine d'espèces acceptées.

Considéré précédemment comme un sous-genre du genre Lotus (taxon principalement terrestre), Hosackia a été maintenu comme un genre distinct à la suite d'analyses phylogénétiques. Ce taxon présente un bien plus grande affinité pour les zones humides^[2].

Étymologie

Le nom générique, « Hosackia », est un hommage à David Hosack (1769–1835), médecin et botaniste américain^[2].
