Talk:Dryopteris carthusiana

Untitled

The common name of Dryopteris carthusiana is the Spinulose Wood Fern. It is bipinnate-pinnatifid and very fern-like; usually found in rich, moist woods. The pinnules are spiny-toothed (hence the name), turning inward, with the longest pinna about the center of the blade. The Spinulose Wood Fern and its varieties are so closely alike and cross breed so readily, that it is difficult to separate the varieties and forms one from another. The best field marking, however, is that the first pinnule of the bottom pinna is the longest. There are light brown scales on a stipe which is about 1/4 of the frond length, and the lower pinnules of the basal pinnae will get longer as they approach the rachis, while the upper pinnules remain evenly small.— Preceding unsigned comment added by 205.188.116.9 (talk • contribs) 5 January 2006‎ (UTC)
