Seed morphology of Linaria species from eastern Spain: identification of species and taxonomic implications
Abstract 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.
Taxonomic Study of Linaria depauperata and L. supina Complexes in Eastern Spain
Abstract Morphological characteristics were studied in two groups of closely related taxa of section Supinae , Linaria depauperata and L. supina , from eastern Spain. Vegetative, floral and seed characteristics were of little use in distinguishing between these taxa as the ranges for all the taxa studied overlapped. Flower colour could be used as a diagnostic character for some but not all of these taxa. Seed coat characters were of high taxonomic value, both when trying to distinguish among these two groups, and the taxa included within them, and also when establishing relationships among the taxa studied. Some differences were found in the indumentum distribution and density. Three types …
