Abstract

Linum aksehirense (Linaceae) is described as a new species known from the slopes of the Sultan Mountains in the Akşehir district of Konya in Central Anatolia (Turkey). It is most similar to L. pubescens Banks & Sol. and L. anisocalyx P.H.Davis, from which it is easily distinguished by its stem leaf shape, sepal shape and petal colour. Seed and pollen surface ornamentations were photographed under SEM microscopy to explore micromorphological characters distinguishing the new species from close relatives. In addition, photographs of living material, a distribution map, ecological details, and an identification key are provided.

Highlights

The genus Linum Linnaeus (Linaceae) is comprised of about 200 species in the Linaceae family
Linum aksehirense is similar to L. pubescens, L. anisocalyx and L. viscosum in morphology
Linum aksehirense differs from L. pubescens by its spatulate, not evanescent lower stem leaves, lanceolate-elliptic, acute median stem leaves, 16–19 × 3–4 mm, subequal lanceolate sepals, sepal size of 12–14 × 2–3 mm and its petal colour, which is blue-violet with a yellowish limb base (Table 1)

Summary

Introduction

The genus Linum Linnaeus (Linaceae) is comprised of about 200 species in the Linaceae family. Linum is distributed mainly in North America, the Balkan Peninsula, Anatolia, as well as in Eurasia and Africa (Robertson 1971), but it is represented in South America and Australasia. Linum was first described by Linnaeus (1753). The f irst comprehensive study on the genus was made by Planchon (1847, 1848). The most recent worldwide treatment of Linum was done by Winkler (1931). According to Winkler (1931) and Planchon (1847, 1848), Linum is divided into five sections. The genus has been the subject of several taxonomic studies and regional revisions, such as those focusing on American
