Leonurus quinquelobatus Gilib.

Leonurus quinquelobatus Gilib. in Usteri, Delect. Opusc. Bot. 2: 321 (1793).

Leonurus quinquelobatus Leonurus villosus Leonurus cardiaca subsp. villosus

Leonurus quinquelobatus Leonurus cardiaca

Diagnosis

The species differs from Leonurus cardiaca L. s. str. by its calyces and stems with abundant long hairs throughout (vs. glabrous or sparsely pubescent along ribs) and lower cauline leaves deeply divided into narrow lobes (vs. dissected into broad lobes) ( Gladkova and Menitsky 1978).

Distribution

Native distribution

Crimea, Caucasus, Iran.

Secondary distribution

Europe, Asia.

Distribution in neighbouring territories

Locally established neophyte in southern Finland ( Kurtto 1998a) and southern Karelia ( Kravchenko 2007).

New record

Russia. Murmansk Region. Terskii District. Kuzreka Village, near Botaminskaya fishing station, 66.598067°N, 34.834799°E, on a seashore meadow in a holiday village, 05.07.2018, M. Kozhin M-4036 (H, MW 1058418, KAND 10122).

Pathways of introduction

Escape from confinement: Ornamental purpose other than horticulture.

The species has been traditionally cultivated as folk medicine, although nowadays it practically fell into disuse and can seldom be found in cultivation.

Period of introduction

Russia (after 1991).

The record originated from a well-explored area, from which the species has not been known in the previous times. Its introduction is therefore considered recent.

Invasion status

Locally established neophyte, persisting but not spreading far from the original place of introduction.

Ecology

Mountain forests and shrublands.

Biology

Perennial polycarpic. Hemicryptophyte with short rhizome.

Notes

Kozhin (2014) reported the first occurrence of Leonurus quinquelobatus in Murmansk Region, which was based on a specimen collected from Umba Village. That plant was a misnamed specimen of L. cardiaca L. s.str.
