Absinthium,-ii (s.n.II), abl.sg. absinthium, also apsinthium,-ii (s.n.II), abl.sg. apsinthio: wormwood (Lewis & Short); “an infusion or tincture of wormwood” (Glare); from the Greek, ‘apsinthium Ponticum,’ wormwood, Artemisia apsinthium or pontica; apsinthium Santonicum, a species of wormwood, Artemisia glacialis or mutellina; apsinthium marinum, a species of wormwood, Artemisia maritima (Glare);

- Muscus palustris absinthii folio insipidus, an [insipid] swamp moss with the leaf of absinthium.

From the protologue of a liverwort [now Trichocolea]. Artemisia absinthium ‘absinthium, or absinthe wormwood, wormwood’ is a species of Artemisia. The liverwort has Artemisia-like leaves, i.e. highly dissected. The ‘insipid’ may have to do with the taste, which is not as strong (bitter) as Artemisia, which is used in flavoring, especially spirits and wine. Both the tiny liverwort and the giant Artemisia absinthium have dissected leaves and both share the greenish-gray color, the silky silvery-white trichomes on the vascular plant are also like the cilia of the hepatic.

NOTE: Artemisia absinthium: the epithet is a noun in apposition.

Absinthium umbelliferum (Ray) “Tenuissimè dissectis” extremely finely dissected.
