Common Name: FLOATING-FERN or WATER-SPANGLE FAMILY Habit: Free-floating aquatic; roots 0. Stem: horizontal. Leaf: in groups of 3 along stem, each group of 2 floating leaves, 1 submersed; floating leaves simple, +- sessile or short-petioled, generally ovate to cordate, entire, notched at tip or not, green, hairy, hairs water-repellent on upper face; submersed leaf dissected, root-like, generally petioled, +- white, hairy. Sporangia: in +- spheric, indehiscent cases of 2 kinds, submersed, on axes in chain-like arrangements or on leaves. Sporangium Case: few to many; sporangia many per case; spores 32 or 64 per sporangium, spheric, in hard mass. Male Sporangium Case: few to many; sporangia many per case; spores 32 or 64 per sporangium, spheric, in hard mass. Female Sporangium Case: 1--few, basal; sporangia few per case; spore 1 per sporangium, spheric. Genera In Family: 1 genus, +- 10 species: +- worldwide, generally tropics. Note: Closest relatives of Azollaceae. In California, probably all are escapes from cultivation, aquaria, reproducing vegetatively (fertile material documented in California only for Salvinia minima). eFlora Treatment Author: Bruce G.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
