Morphometric study of genus Convolvulus L. in Iran

The genus Convolvulus is considered to be part of the Sahara-sindian elements mainly distributed from the central part to the southern part of Iran. The morphological traits of this genus were studied for systematic purposes. For this purpose, after collecting different populations of this species from different natural habitats, the aerial parts of the plant were subjected to optical microscopic morphometry .The results showed that among 60 selective attributes based on the available resources in this genus, some of the morphological traits such as shape, size, and shape of the calyx, the establishment of flowers on the shoot, shape of indumentum in the ovaries, could be considered as systematic traits in this genus. So, after quantitative and qualitative morphometric study, the calyx (calyx shape, calyx apex, calyx size), is possible to group the species within this genus, for example, a calyx shape (ovate, lanceolate, rectangular, rounded) is created four major groups in this genus leading to subgenus classifications in this genus
