The genus name
Thymelaea is a combination of the Greek name for the herb
thyme θύμος (thúmos) and that for the
olive ἐλαία (elaía) - in reference to its thyme-like foliage and olive-like fruit; while the English name Sparrow-wort (used by Thomas Green in his
Universal Herbal, published 1820) is a translation of the name of the genus
Passerina (in which
Thymelaea was formerly placed), derived from the word
passer "
sparrow" - given the plants in reference to a perceived similarity of the shape of the fruit to a sparrow's beak. ==Species==
