Stem anatomy and ontogeny of vascular variants in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae)

open access: yesNordic Journal of Botany, Volume 2026, Issue 2, February 2026.
An increase in stem thickness and ontogeny of successive cambia, intraxylary cambium, and inter‐and intraxylary phloem is elaborated for the first time in Ipomoea asarifolia (Desr.) Roem. & Schult.
