Mesa Spikemoss

Selaginella cinerascens A. A. Eat.

Comments

provided by eFloras
The light brown and grayish mats, short lateral branches, narrow stem, and short strobili distinguish Selaginella cinerascens from all other species in the flora, in which it has no close relatives. R. M. Tryon (1955) related S . cinerascens to S . arsenei Weatherby from Mexico. Selaginella cinerascens also closely resembles S . nivea Alston from Madagascar. In California S . cinerascens is known only from San Diego County.

Plants terrestrial, forming loose to compact mats. Stems creeping, not readily fragmenting, upperside and underside structurally slightly different, irregularly forked, without budlike arrested branches, tips straight; main stem indeterminate, lateral branches determinate, ascending, 1--2-forked. Rhizophores borne on upperside of stems, throughout stem length, (0.17--)0.2--0.3 mm diam. Leaves monomorphic, not in defined pseudowhorls, loosely appressed, ascending, green, linear-lanceolate, (1--)2.5--3 X (0.25--)0.4--0.6 mm (leaves in secondary and tertiary branches smaller); abaxial ridges inconspicuous; base rounded and adnate or cuneate and slightly decurrent, glabrous, seldom pubescent; margins short-ciliate, cilia transparent, scattered, ascending, 0.02--0.75 mm; apex plane, blunt, acute to slightly acuminate (not distinctly bristled).

Selaginella cinerascens

provided by wikipedia EN

Selaginella cinerascens is a species of spikemoss known by the common names mesa spikemoss,[4] gray spikemoss, and ashy spikemoss. It is native to Baja California as well as some locations just north of the border in San Diego County, California. It grows in dry habitat, often on clay soil, both in open areas and in the shade of larger plants. This lycophyte forms mats of spreading, forking stems up to 18 centimeters long. The plant is often gray or brown in color, forming a dull-colored carpet on the substrate. The linear or lance-shaped leaves are 1 to 3 millimeters long and lack bristles at the tips. The leaves are green when new or moist. They are flattened to the stem or stick out just a little. The strobili borne at the leaf bases are yellow in color and no more than 4 to 5 millimeters long.
