English Wikipedia has an article on:
Conium maculatum, one of the umbellifers called hemlock
Tsuga heterophylla, one of the conifers called hemlock


From Middle English hemlok, hemeluc, from Old English hymlīc, hymlīce (hemlock, bryony, convolvulus, literally hops-like), from hymele (hop-vine), from Proto-Germanic *humalaz, *humalōn, of unknown origin. Perhaps from Scythian, from *háwmah (ephedra; juice), from Proto-Indo-Iranian *sáwmas from Proto-Indo-European *sew- (to press out, extract).
