- Abstract
Background and aims: The taxonomy of the 1700 scientific names of Lupinus is very complex, due to the high number of species described by C. P. Smith. For Argentina, 36 valid taxa, 55 synonyms and 1 dubious taxon are cited. The objective was to re-evaluate three cespitose species of less than 25 cm in height, with inflorescences covered by the leaves, treated as a complex in 1980 and to analyze two others that share the same structural characteristics. M&M: Nomenclatural types, herbarium specimens, JSTOR images, virtual herbariums and plants studied in the field were evaluated. Vegetative and floral organs, leaflet epidermis and seed integuments were analyzed with stereomicroscopes and scanning electron microscopy. Conservation status was assessed taking into account environmental factors. Results: The following nomenclatural changes are presented: Lupinus andicola var. andicola; L. andicola var. alivillosus: L. andicola var. grisebachianus; L. andicola var. subacaulis and L. andicola var. subinflatus. The key vegetative characters are: indumentum of the stems, petioles and adaxial face of leaflets and relationship of the lengths of petioles versus leaflets. The discriminant floral characters are: shape and size of the banner and the lobes of the upper lip of the calyx. It provides: identification key to the varieties, observations, common names, etymologies of epithets, state of conservation, list of material studied, illustrations and distribution maps. Conclusions: The work provides an updated and complete evaluation for a group of taxa of the Argentine flora with correction on types citation and new conservational status assigned.
