Abstract

The protologue, original material and typification of the Linnaean name Thymus pulegioides (Lamiaceae) are discussed. The specimen Herb. Linnaeus No. 38.5 (LINN) has been regarded as the lectotype of T. pulegioides, and perfectly agrees with the protologue of this name, but appears not to have been effectively designated as such. Therefore, the lectotype must be Herb. Linnaeus No. 38.6 (LINN), which was effectively designated by Martonfi in 1997.Citation: Nachychko V. O. & Sosnovsky Y.

Highlights

Thymus L. (Lamiaceae) includes c. 215 species occurring in the Old World north of the equator to southern Greenland and subarctic Eurasia, with the centre of diversity in the Mediterranean region (Morales 1989, 2002; Sostaric & al. 2012)
Linnaeus No 38.5 (LINN) as the lectotype of T. pulegioides designated by Ronniger (1944), and this viewpoint was subsequently adopted by modern monographers of Thymus (Bartolucci & al. 2013; Knyasev 2015; Nachychko & al. 2019a)
This work is based on the analysis of the protologue of Thymus pulegioides (Linnaeus 1753: 592), one preLinnaean publication (Morison 1699) cited there, and the Linnaean herbarium collection at Linnaeus No 38.6 (LINN)
