Seed morphology of Linaria species from Eastern Spain: Identification of species and taxonomic implications
Seed morphology of 15 taxa of Linaria from eastern Spain has been studied using stereoscopic and scanning electron
microscopy. Four different morphological types are described according to features of the seed-coat surface. The
type that includes winged seeded taxa is divided into three subtypes. Seed morphology of each type and subtype is
described, compared, illustrated and discussed according to its taxonomic and biological implications. A key to
identify the different species or groups of species is also supplied.
