Abstract

Sisyrinchium angustifolium Mill. (Iridoideae, Sisyrinchieae) has been reported as a new record for the flora of Turkey from NE Anatolia, and taxonomic and conservation status of this species are evaluated. Detailed morphological description, leaf and stem anatomical properties, and chromosome numbers are provided. The present chromosome count is the first tetraploid level for this species reported from Eastern Anatolia, Turkey.DOI: http://dx.doi.org/10.3329/bjpt.v21i2.21357Bangladesh J. Plant Taxon. 21(2): 175-180, 2014 (December)

Highlights

Sisyrinchium L. (Iridoideae, Sisyrinchieae) includes approximately 200 species (Rudall et al., 1986) and occurs in wet to dry grasslands, rocky or sandy soils, and in highly transformed areas, such as roadsides or grazed and burned fields at elevations of up to 800 m (Bicknell, 1899)
During fieldwork in Artvin Province (Turkey) some interesting specimens belonging to Iridaceae were collected
After critical study and consultation with relevant literature (Fedchenko, 1968; Davis, 1984, 1988; Güner et al, 2000; Özhatay et al, 2011), the specimens have been identified as Sisyrinchium angustifolium Mill

Summary

Introduction

Sisyrinchium L. (Iridoideae, Sisyrinchieae) includes approximately 200 species (Rudall et al., 1986) and occurs in wet to dry grasslands, rocky or sandy soils, and in highly transformed areas, such as roadsides or grazed and burned fields at elevations of up to 800 m (Bicknell, 1899). During fieldwork in Artvin Province (Turkey) some interesting specimens belonging to Iridaceae were collected. After critical study and consultation with relevant literature (Fedchenko, 1968; Davis, 1984, 1988; Güner et al, 2000; Özhatay et al, 2011), the specimens have been identified as Sisyrinchium angustifolium Mill. S. angustifolium is the first species of the genus Sisyrinchium to have been reported for Turkey. The number of genera of Iridaceae in the flora of Turkey is increased to 6 with addition of Sisyrinchium. We aim to describe detailed morphological characters of Sisyrinchium angustifolium, to determine its conservation status, and distribution along with exploring the anatomical and cytological properties of the newly recorded species
