nbotrychiumA genus of cryptogamous plants, natural order Ophioglossaceæ, allied to the ferns. They bear clustered, veinless sporangia in contracted panicled spikes above the variously divided frond. There are several widely distributed species, known by the popular name of moonwort, from the crescent shape of the divisions of the frond in some common kinds. The name grape-fern is also given to them, and one species, B. Virginianum, is called rattlesnake-fern.
Close to Premsong's I gathered a Clematis, Valerian and a fine Botrychium, a Carex and a Cuscuta.
