Revisión del género Valeriana (Valerianaceae) en Sudamérica austral

Abstract

RESUMENEl género Valeriana es el más diverso de la familia Valerianaceae y se encuentra ampliamente distribuido en las zonas templadas del hemisferio norte, África y Sudamérica, presentando en la región andina un importante centro de diversificación secundaria. Este trabajo comprende la revisión de las especies de Sudamérica austral sobre la base de material de Argentina y Chile desde los 33ºS hasta los 55ºS. Se describen 40 especies de Valeriana de esta región, se citan ilustraciones ya publicadas y se incluye una clave para identificarlas. Se incluyen sinonimias nuevas basadas en el estudio de los tipos nomenclaturales y se lectotipifican varios taxones. Se hace referencia a las características distintivas de cada especie, su fenología, distribución geográfica y hábitat, material adicional examinado y afinidades taxonómicas. Se amplía la distribución geográfica de algunas especies y se citan nuevos registros para Argentina y Chile. PALABRAS CLAVE:Argentina, Chile, taxonomía, Valeriana, sinónimos, lectotipificación. ABSTRACTThe genus Valeriana is the most diverse of the Valerianaceae family and is widely distributed in temperate northern hemisphere, Africa and South America, presenting in the Andean region an important center of secondary diversification. This work includes the review of species of southern South America based on material from Argentina and Chile south of latitude 33° S. Forty species of Valeriana are described for this region, references of published illustrations are given and a key is provided for their identification. New synonymies and lectotypes based on the study of type material are included. Notes on phenology, geographic distribution and habitat, additional material examined, distinguishing characters and taxonomic affinities are also given. Some species had not been reported previously for Argentina or Chile.

A New Species of <I>Valeriana</I> from the Andean Region of Northwestern Argentina Based on Morphological and Molecular Data

“…To create the key to the Argentinian species of Valeriana with epappose fruits we borrowed from the key of Valeriana of Borsini (1944) and Kutschker (2008aKutschker ( , 2011. Additionally, we consulted original descriptions and regional floras of Argentina (Borsini 1942(Borsini , 1946Cabrera 1993;Borsini 1999;Novara 2008;Méndez 2010), and reviewed herbarium specimens, some of wich are cited in Appendix 1.…”

“…Most Valeriana species grow in temperate regions of the Northern Hemisphere, and particularly in the South American Andes. The high Andes species range from paramo habitats in the north to the Patagonia region in the south, which is an important center of secondary diversification (Kutschker 2008a(Kutschker , 2011. The Argentinian flora includes 48 species of Valeriana, mainly distributed along the Andes and central mountains (Borsini 1944(Borsini , 1960(Borsini , 1962bXifreda 1999;Kutschker 2008b;Méndez 2010;Kutschker 2011;Zanotti et al 2014).…”

Modeling the potential distribution of Valeriana carnosa Sm. in Argentinean Patagonia: A proposal for conservation and in situ cultivation considering climate change projections

“…Argentinean Patagonia holds 20 species of the genus Valeriana (Borsini, 1999;Kutschker, 2011). Among these, Valeriana carnosa Sm.…”

“…(Valerianoideae, Caprifoliaceae) is one of the medicinal plants most frequently used by Patagonian regional ethnic and rural creole groups (Molares et al, 2018). This species grows in xeric, open, sunny environments on rocky or sandy soils of the forest, low sunny slopes of the Patagonian-Andean forest-steppe ecotone and in the highest mountains of the steppe region (Kutschker, 2011). It is an evergreen shrubby herb of up to 60 cm in height, ramified, with woody rhizomatous stems and thickened main roots (Fig.…”

Confirmation of Valeriana nivalis (Valerianaceae) to the Argentinian flora

“…250 species distributed all over the world except australia and New Zealand. Most Valeriana species grow in temperate regions of the northern hemisphere, and particularly along the South american andes, which is an important center of secondary diversification (Kutschker 2008a(Kutschker , 2011. the argentinean flora includes 48 species of Valeriana, mainly distributed along the andes and central mountains (Xifreda 1999, Kutschker 2008b, 2011.…”
