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.

Identification

The flowerhead is branched and has a ridged stem Catapodium rigidum rhachis.jpg
The flowerhead is branched and has a ridged stem

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]
