Wikipedia 설명
Anemia mexicana, the Mexican flowering fern, is a fern species in the genus Anemia, sometimes called flowering ferns. It is native to much of Mexico and the Edwards Plateau and Trans-Pecos regions of Texas. The "flowers" are upright fertile fronds that can be mistaken for true flowers.[1][2]
Description
The fronds of Anemia mexicana arise at intervals (rather than in a tight clump) from a horizontal rhizome about 2 millimeters (0.08 in) in diameter, covered with stiff, dark brown hairs. The fronds are upright and are, in total, 30 to 60 centimeters (10 to 20 in) long, occasionally as short as 15 centimeters (5.9 in). About half of that length is the stipe (the leaf stalk, below the blade), which is about 1 millimeter (0.04 in), hairless, and straw-colored.[3]
