Abstract

The genus Thymus is one of the genera in the family Lamiaceae . In Ethiopia, it is represented by two endemic species namely Thymus serrulatus and Thymus schimperi . The aims of this study were to identify the types of species from six geographically distant localities in Ethiopia, assess the ethnobotanical and socioeconomic information of these species in these localities and gather information about the current status and threatening factors of these species in the six localities. The plant specimens from these localities were authenticated by experts in the National Herbarium of Addis Ababa University as Thymus serrulatus and Thymus schimperi . The plants were rated by local informants as treatments for ailments like blood pressure (30.7%), general pain syndrome (10%), influenza (10%), abdominal pain (10%), ascariasis (2.9%), and intestinal parasites (2.9%). The informants rated the economic value of these plants as animal forage (71.5%), bee forage (71.5%), condiments (68%), and washing and fumigation (46%). According to the informants, the status of Thymus species is declining from time to time due to overgrazing (80.7%), agricultural expansion (64.2%), overharvesting (48.57%), uprooting during harvesting (14.2%), and lack of recognition (13.6%) Keywords: Ethiopia, Thymus schimperi , Thymus serrulatus , threatening factors

Highlights

The Lamiaceae/Labiatae (WHO, 1999) is a large plant family represented by about 236 genera and above 7200 species (Hedberg et al, 2006)
In Ethiopia, this genus is represented by two indigenous species namely T. serrulatus and T. schimperi (Jaafari et al, 2007) both of which are locally named as Tosign (Amharic) and Tesni/Thasne (Tigrigna)
Identified Thymes species collected from six localities in Ethiopia Out of the Thymus species collected from six localities, three of them (Ofl-2013, Ala-2013, and Yil-2013) were identified as T. serrulatus and the rest three (Tar2013, But-2013, and Bal-2013) as T. schimperi (Table 1)

Summary

Introduction

The Lamiaceae/Labiatae (WHO, 1999) is a large plant family represented by about 236 genera and above 7200 species (Hedberg et al, 2006). In Ethiopia, this genus is represented by two indigenous species namely T. serrulatus and T. schimperi (Jaafari et al, 2007) both of which are locally named as Tosign (Amharic) and Tesni/Thasne (Tigrigna). These species are endemic to Ethiopian highlands Thymus schimperi is widely distributed in central, eastern, and northern Ethiopia and T. serrulatus is restricted to northern parts of the country (Sebsebe Demissew and Nigist Asfaw, 1994). T.schimperi is widely distributed in Amhara, Oromia, and Southern Nations Nationalities and Peoples Regions
