In internal structure of lamina two distinct groups are recognized within Onosma; sections Protonosma M. Pop. and Podonosma (Boiss.) Gruck with dorsiventral mesophyll and sect. Onosma mainly isobilateral. Several anatomical characters are associated with xeromorphy. Leaf anatomy supports the division of the genus Onosma L. into 3 sections.   UR - https://ijb.areeo.ac.ir/article_103392.html L1 - https://ijb.areeo.ac.ir/article_103392_bf0d2d6df23f1beb7b2d89cb625c9417.pdf ER -
