Equivalent width of the Li I λ6707.8 line (WLi) plotted as a function of Teff (open circles for giants, purple dots for MS stars). The lines show the upper boundaries for Hyades (dash-dotted blue), Pleiades (solid red for both the lower and upper boundary), and IC 2602 (dashed orange) clusters. Most of the stars with a strong lithium absorption are lithium-rich giants.
