Trichomanes (Greek, soft hair). Hymenophyllaceae. A group of filmy ferns distinguished by its tubular cup-like indusium and filiform elongate receptacle. (Fig. 3837.) Very delicate in texture and capable of being grown successfully only under shaded glass. Over 100 species are known. Various species may be found in the collections of fanciers, but the following appear to be the only ones regularly in the American trade. For culture, see Ferns. | Trichomanes (Greek, soft hair).
