Abstract

Geranium biuncinatum Kokwaro was collected during a fieldwork around (Khuzestan province, Shoshtar to Masjed Soleyman) in South West of Iran. It is added as a new record for the flora of Iran. Micromorphological features of mericarps and seeds are investigated by Scanning Electron Microscopy. Differences between Geranium biuncinatum and its relatives are discussed. Its diagnostic characters, geographical distribution map and detailed pictures are given.

Highlights

The genus Geranium L. is a member of Geraniaceae family with about 325 species which are distributed through most parts of the world except lowland tropical regions (Aedo, 2017)
Trilopha Yeo, which consists of seven species: Geranium biuncinatum Kokwaro, G. favosum Hochst., G. mascatense Boiss., G. ocellatum Cambess., G. trilophum Boiss., G. yemense Deflers. and G. brevipes Hutch. & Dalziel
This study provides the macro and micro-morphological characters used for the species delimitation in Geranium sect

Summary

Introduction

The genus Geranium L. is a member of Geraniaceae family with about 325 species which are distributed through most parts of the world except lowland tropical regions (Aedo, 2017). Different number of species from 23 to 25 is recorded for the flora of Iran (Schönbeck-Temesy, 1970; Janighorban, 2005; Esfandani-Bozchaloyi et al, 2017 a, b, c, d). The subgenus Robertium is recognized by the carpel projection method for fruit discharge. It has been divided into eight sections. Trilopha Yeo, which consists of seven species: Geranium biuncinatum Kokwaro, G. favosum Hochst., G. mascatense Boiss., G. ocellatum Cambess., G. trilophum Boiss., G. yemense Deflers. Two species of this section were previously recorded for Iran: G. mascatense and G. trilophum (Schönbeck-Temesy, 1970). In the present paper we are adding G. biuncinatum for the Flora of Iran With this new record the total number of Geranium species known from Iran rises to 23.
