Lithium abundances (in the scale of log N(H) = 12) versus Teff for Hyades solar-type stars (black dots; Cummings et al. 2017), K5–M4 stars (upper limits; Zboril et al. 1997), the mean value for L3.5 members (blue dot; Martín et al. 2018), and the BD 2M0418 (red dot). The range of initial lithium meteoritic content is shown with red dotted lines as an upper limit of the possible content in BD atmospheres.
