Abstract

BENCI ARQUED, José et al. Taxonomic circumscription of Schinus pilifera (Anacardiaceae) and reproductive characteristics of a population from La Calderilla, Salta, Argentina. Lilloa [online]. 2019, vol.56, n.2, pp.18-36. ISSN 0075-9481.  http://dx.doi.org/https://doi.org/10.30550/j.lil/2019.56.2/2.

Schinus pilifera is a native shrub from northern and central Argentina with a wide distribution in seven provinces also found in southern Bolivia. It a very polymorphic species that has been split into three intra-specific varieties: var. piliferus, var. boliviensis and var. cabrerae based on leaves pubescence and glabrescence characteristics. No information was found about the morphological variation, or sexual and reproductive systems of this species. The objectives were to obtain general morphological information on the reproductive system and analyze the validity of the intraspecific taxa. LIL and MCNS herbaria collections were studied, as well as the virtual ones from BM, GH, MO and NY herbaria. New collections were made in different environments of Salta and Tucumán to recognize and analyze the variation among populations. Several morphological and reproductive aspects were studied of a population from La Calderilla, Department La Caldera (Salta), located in an old bed of La Caldera River at 1300 m asl. It was concluded that the characteristics defining the varieties were confusing, reasonwhy they were invalidated and passed to the synonymy. The species is dioecious. The pollination is ambophilc
