Stipules shortly adnate to it, vaginate-connate behind stem. Inflorescences usually long, loosely to remotely flowered, elongated in fruit. Petals free, mostly violet when dry; Wings shorter than Standard and longer than Keel. Legumes linear, long, often slightly to more rarely distinctly constricted between seeds, 2-locular, valves leathery, appressed hairy. + + + + +FIGURE 1 +. Holotype of + +Astragalus taledensis +P.

Stems several to numerous, nearly prostrate, the middle-upper part of the stems dichotomous branching.

Species with a very restricted distribution area (e.g. + +Brullo +et al. +2012 + +; + +Musarella +et al. +2020 + +, + +Perrino +et al. +2021 + +) are often considered either as Critically Endangered/ Endangered (CR/EN), according to +IUCN (2019) +criteria B and/or C (e.g. + +Wagensommer +et al. +2017 + +; +Saðiroðlu & Eker 2021 +; +Wagensommer & Venanzoni 2021 +), or as not threatened/near threatened (LC/NT), especially if there is no observed decline (e.g. + +Perrino +et al. +2018 + +). Thus, more exploration in the area is necessary for the definition of the distribution, population size, threats, etc., before being able to recommend a conservation status. + + + + \ No newline at end of file
