Generic delimitation between Alstroemeria and Bomarea (Alstroemeriaceae)

The taxonomic relationships between Alstroemeria and Bomarea, two closely related genera in Alstroemeriaceae, are controversial. With the aim of clarifying their systematic position and generic circumscription, morphological and anatomical studies were carried out on 18 species of Alstroemeria and 1...
