woodsia, with oo.
two letters, one vowel
English has at least four ways of writing this vowel, and ou is one of the good ones: could, should, would. That last one is the problem, because would and wood are said identically and only one of them has anything to do with this fern. The genus is built on the surname Woods, and Woods is spelled with a double o.
