Description
Species Description - Plants terrestrial, with horizontal-arching or assurgent main stems bearing at intervals several erect, feathery aerial branches, or sometimes the main stem itself erect, the lowermost branches decurved-spreading, elongate, and stoloniferous. Erect stems 30- 100 cm long, giving rise to numerous spreading, freely branched, densely leafy lateral divisions, the ultimate branchlets (when fertile) ending in sessile cylindric-conic strobili. Leaves of main stem spirally arranged in 16-24 ranks, often appearing nearly whorled, subulate-attenuate, mostly entire, spreading or reflexed, keeled and decurrent adaxially at base. Lateral branches to 15 cm long, bearing leaves similar to those of the main stem but slightly smaller and strongly upcurved. Strobili often numerous, downwardly directed; sporophylls appressed-imbricate, in about 10 ranks, triangular- acuminate. Sporangia subglobose with unequal valves, concealed.
