M. Bigazzi et al., ANCHUSELLA, A NEW GENUS OF BORAGINACEAE FROM THE CENTRAL-EASTERN MEDITERRANEAN, Plant systematics and evolution, 205(3-4), 1997, pp. 241-264
The two closely related species Lycopsis variegata and Anchusa cretica
, formerly placed in Anchusa subg. Rivinia, were compared with the typ
e species of Lycopsis and Anchusa, on the basis of a set of macro and
microcharacters. The presence of only two fertile stamens as well as o
ther peculiar characters in flower structure, androecium, gynoecium, p
ollen and fruit, supports the institution of the new genus Anchusella,
consisting of A. variegata and A. cretica. Karyological and eco-choro
logical aspects are consistent with morphological data in pointing to
the autonomy of this genus, which appears characterized by autapomorph
ic, advanced traits.
