Lechea (pinweed) is a genus in the family Cistaceae of the order Malvales.2 The genus contains about 18 species referred to as "pinweeds" primarily in eastern North America. Most are low-growing herbs with narrow leaves and many small flowers that resemble pinheads.3

Linnaeus named the genus Lechea for Swedish botanist Johan Leche (1704–1764), who taught in Finland and is regarded as the father of Finnish meteorology and space research, based on his documentation of the northern lights and early measurements of air temperature in collaboration with Anders Celsius.4
