Mophological, anatomical, palynological and caryological investigations on endemic Lathyrus undulatus Boiss. (Fabaceae)

In this study, morphological, anatomical, palynological and caryological characteristics of endemic Lathyrus undulatus Boiss. which have spread in Turkey's northwestern is analyzed. The materials used in this study from the L. undulatus species are collected in May-June of 2016 and 2018 from İstanbul and Bursa provinces. In addition to this, also herbarium samples are used.
