The Venus-hair fern {Adiantum Capillus-Veiieris) encir- cles the world in the Tropics and in both Hemispheres spreads toward the Poles as far as it finds suitable dwell- ing places. In the Old World it extends to Great Britain and in North America to Virginia, Kentucky, Mis- souri, Utah and California. It de- lights in moist and sheltered situa- tions and in the northern parts of its range should be looked for in ra- vines. It may be distinguished from the common maidenha
. Our ferns in their haunts; a guide to all the native species. Ferns. 246 CHEILANTHES AND MAIDENHAIR. The Venus-hair Fern. The Venus-hair fern {Adiantum Capillus-Veiieris) encir- cles the world in the Tropics and in both Hemispheres spreads toward the Poles as far as it finds suitable dwell- ing places. In the Old World it extends to Great Britain and in North America to Virginia, Kentucky, Mis- souri, Utah and California. It de- lights in moist and sheltered situa- tions and in the northern parts of its range should be looked for in ra- vines. It may be distinguished from the common maidenhair by its dark, wiry undivided rachis and fan- shaped, drooping pinnules on ex- ceedingly slender black stalks. The rachis gives off alternate branches and the pinnules are also arranged alternately. The blade is usually twice pinnate below and simply pin- nate above and the pinnules are not one sided as in many species of Adi- antum. Their outer edges are rounded, rather deeply notched and serrate. There is great variation in the form of both pinnules and fronds. When the pinnules die, they drop from the rachis which remains erect for some time longer. Nearly every frond is fertile. The sori scarcely differ from \\\q'!,& oi A. pcdatttni. Specimens have been reported in which the spores gave rise to young plants while still on the VEMUS-HAIR p-ERN. Adiantuvi Capillus-Veneris,.
