Anemia hirsuta

Smith, Alan R. & Kessler, Michael, 2017, Prodromus of a fern flora for Bolivia. XIII. Anemiaceae, Phytotaxa 329 (1), pp. 80-86 : 83

Anemia hirsuta (L.) Sw., Syn. Fil. 156. 1806.

Range:— Greater Antilles, Trinidad-Tobago; Mexico to Bolivia (LP, SC) and Brazil.

Ecology:— Uncommon; terrestrial in dry, grassy areas, on open slopes, and on road banks and roadsides; 500– 1750 m.

Notes:— A variable, widespread, tetraploid species, of variable size, pinnae nearly undivided to deeply lobed or lacerate, and blade shape oblong to deltate. Differs from Anemia hispida by the broader, mostly deeply incised (even lacerate) sterile pinnae (vs. crenulate or denticulate, rarely with a few deep lobes), and more narrowly cuneate pinna segments. Hybridizes with A. hispida , A. phyllitidis , and other species, especially in Mexico and Brazil ( Mickel 2016). Sundue & Nee 691 (UC), without fertile pinnae, was identified by Mickel (2013) as A. hirsuta × hispida , but this appears to us to be typical A. hirsuta .

Bolivian collections previously determined as Anemia wettsteinii Christ are now considered other species, e.g., A. hirsuta .
