Lepidium chalepense.
(Lens Pod Pepperwort, Whitetop). Synonyms: Cardaria chalepensis, Cardaria draba variety repens. Brassicaceae (Mustard Family) Foothills. Fields, lawns, roadsides, disturbed areas.
Spring, summer. Lepidium chalepense is an invasive, alien species that grows to two feet tall, often with a robust set of lower leaves and progressively smaller upper leaves. Flowers are quite tiny and seed pods grow rapidly. Linnaeus named the Lepidium genus in 1753 and he also named this species, Lepidium chalepense. "Lepidion" is Greek for "little scale" and refers to a scale on the seed pod. The Cardaria genus was named by Desvaux. Handel-Mazzetti renamed the plant Cardaria chalepensis in 1913. The Greek "card' means "heart" which refers to the heart-shaped seed pods of Cardaria draba. Michael Charter points out on his "CalFlora Names" website, that the "-ense" ending is a Latin adjectival suffix usually used to indicate the country of origin. In this case there are two possible places: (1) Aleppo, Alep, or Haleb, a city in northwestern Syria. Allepo is also referred to in the form aleppica, aleppicum, aleppicus, and halepensis (2) Halepa, in Greek: Khalepa, a city in Greece on the island of Crete near Canea. |
