Description
Tripleurospermum maritimum is a herbaceous plant that grows as a biennial or short-lived perennial.[3] They are usually procumbent, grow along the ground before turning upwards towards the end, but may grow straight upwards. Most often they reach 10 to 80 centimeters (4 to 31 in) in length.[4] The leaves are divided with the ending segments narrow with a fleshy, succulent texture.[5]
The daisy-like flowering heads measure from 3 to 5.5 cm (1.2 to 2.2 in) across.[5] The seeds are achenes that measure 1.8 to 3.5 mm long and can be pale to blackish-brown.[4]

Taxonomy
Tripleurospermum maritimum was given the scientific name Matricaria maritima by Carl Linnaeus in 1753. The botanist Wilhelm Daniel Joseph Koch moved it to the genus Tripleurospermum in 1845 giving the species its accepted name. With the rest of its genus it is part of the family Asteraceae.[2]
Names
The species name, maritimum, is Botanical Latin derived from mare meaning sea referring to its usual habitat.[6] It is known by the common names false mayweed,[7] sea mayweed,[6] seaside chamomile,[8] or false chamomile.[1]
In Iceland, sea mayweed is known as "Baldr's eyelashes" (baldursbrá),[6] though a similar name, baldersbrår, is used for all mayweed flowers in Sweden.[9]
