Some similarities to : Bird's-foot-Trefoils (Lotus species) but flowers are solitary and pale yellow, reflecting its synonym Lotus tetragonolobus.

Uniquely identifiable characteristics

Distinguishing Feature :

No relation to : Dragon Arum (Dracunculus vulgaris) nor to Dragonmouth (a member of the Borage Family, but Americans seem to have an orchid of the same common name), nor to Snapdragon (Antirrhinum majus) [plants with similar names].

Somewhat contrary to its' scientific names reference to the sea (maritimus) it seems not to prefer locations near the sea, but well inland, and mostly in the south of England, but is well scattered even here. There is none north of Manchester (and none in Manchester).
