Catapodium rigidum, ferngrass, is a species of annual grass in the family Poaceae (true grasses), distributed around the Mediterranean and the Middle East. It has been widely introduced throughout drier parts of the world, including parts of North America, South America, South Africa, Korea, Australia, and New Zealand.^[1] Individuals can reach 20 cm (8 in).^[2]

Identification

Fern-grass can be difficult to distinguish from sea fern-grass in places where they occur together, but it has a more open panicle and the stalk to the inflorescence is ridged, whereas it is rounded on one side in sea fern-grass.^[3]^[4]

Subtaxa

The following subtaxa are accepted:^[1]

Catapodium rigidum subsp. hemipoa (Delile ex Spreng.) Kerguélen - more narrowly distributed from Macaronesia and the Mediterranean to Iran
Catapodium rigidum var. majus (C.Presl) M.Laínz - Middle East
Catapodium rigidum subsp. rigidum – entire range, including introductions
