1 The uncertainty in the derived Li abundances is estimated to be around $\pm$0.4-0.6 dex.
2 Possible double lined spectroscopic binary.
3 The lithium line has a P cygni-type profile.
4 Possible non-AGB star.
5 Observed Li abundances in two different runs.
* The abundance value must be treated with some caution because the line is resolved in two components (circumstellar and stellar) and the abundance estimate corresponds to the photospheric abundance needed to fit the stellar component.
** The S/N ratio at 6708 Å is very low to derive any reliable $T_{\rm eff}$ and/or Li abundance estimate.
