Carex scabrifolia; a species of sedge
A specific plant species; used in botanical or ecological contexts. The name is usually written in katakana.
Carex scabrifolia is a plant that grows in wetlands near the coast.
Kanji form is rare and mainly encountered in botanical contexts; the source does not list it as a priority form.
The name likely derives from 潮 (shio, 'tide') and 莎草 (kugu, 'sedge'), referring to its coastal habitat. The exact historical derivation is uncertain.
