A376C721FFAFD707F0DBD8C4A5C8F7EA.taxon	diagnosis	Diagnosis: Schistidium splendens is distinguished from other species of Schistidium by a number of gametophytic characters including the variable but consistent presence of 2 - stratose striae in the distal and sometimes medial portions of the leaf, smooth, thick leaf margins that are recurved to near the apex (the margins are readily visible as dark lines along the leaf borders), relatively short, weakly spinulose awns that are usually non-decurrent, the strongly bulging abaxial costal surface, the relatively small laminal cells, and the often clear basal marginal cells. Distinctive sporophytic characters include the more or less isodiametric or short-elongate exothecial cells that are often irregular in shape, thin-walled, and usually with corner thickenings.	en	Blom, Terry T.

A376C721FFAFD707F0DBD8C4A5C8F7EA.taxon	etymology	Etymology: — The epithet splendens refers to beautiful appearance. Habitat and distribution: — Schistidium splendens is viewed primarily as a semi-rheophytic species, especially in the southern portion of its range where it is often seasonally submerged or inundated during snowmelt and peak rain events along perennial and intermittent streams, often in habitats with diffuse light. However, during most of the year the plants are dry. This ecological partition of habitat along the high water zone of stream and river banks is also similar to that displayed by other western Schistidium species, primarily S. cinclidodonteum (C. Müller Hal.) B. Bremer (1980: 108), S. occidentale (Lawton) S. P. Churchill (1981: 143), and S. rivulare (Bridel) Podpěra (1911: 207). Other occurrences form flat mat-like colonies over rock slabs with seasonal water flow in either intermittent watercourses or rivulets. Less commonly, small colonies are encountered on shaded boulders above the high water mark. The elevation range is from near sea level, especially in the northern portion of its range, to 7400 ft in the Sierra Nevada of California. More important than the surrounding plant community is the availability of microhabitats with periodic inundation which many Schistidium species including S. splendens prefer. To date, S. splendens is restricted to western North America, reported from California, Oregon, Washington, and British Columbia. Comparison: — Schistidium splendens appears closely related to S. pulchrum H. H. Blom (Blom 1996: 119). Both species have margins that are recurved to near the apex, strongly sinuose distal and medial leaf laminal cells, and similar exothecial cell areolation. However, a number of characters differentiate them. The leaf margins of S. splendens are much thicker and more evident than with S. pulchrum which have 1 - or 2 - stratose margins. The awns of S. splendens are usually non-decurrent and have relatively short spinulae, whereas awns of S. pulchrum are often decurrent and have longer, sharper spinulae, and the laminal cells are generally narrower and less thick-walled in S. splendens. The laminal cells of S. pulchrum, especially at mid-leaf, are often guttulate or sometimes stellate in appearance. The capsules of S. splendens are longer, 1.3 – 1.5 mm versus 0.8 – 1.3 mm in S. pulchrum. In addition, the known range of S. splendens does not overlap with S. pulchrum except possibly in British Columbia. Additional specimens examined: — CANADA.

A376C721FFAAD702F0DBDD10A7BDFC32.taxon	etymology	Etymology: — The epithet squarrosum refers to spreading position of the leaves from the stem when wetted. Habitat and distribution: — Schistidium squarrosum is also viewed as a semi-rheophytic species occurring in habitats much like those described for S. splendens. However, some occurrences are in more exposed sites with less water flow such as sheet rock drainages or road banks. Elevation range is primarily between 1000 – 4000 ft. To date, S. squarrosum is restricted to western North America, reported from California, Nevada, Oregon, and Washington. Comparison: — Schistidium cinclidodonteum appears closely related to S. squarrosum and is the species most likely to be confused with it. However, S. cinclidodonteum is usually a larger plant having longer leaves (up to 5.0 mm) whereas leaves of S. squarrosum usually range from 2.2 – 2.8 mm, rarely longer (to 3.0 mm). An efficient way to separate the two species is by examining leaf apices. The leaf apex of S. squarrosum is channeled apically, in contrast to that of S. cinclidodonteum which ends in a terete apiculus. Additional specimens examined: — U. S. A. California.
