Plants erect or ascending to erect from a decumbent base, to ca. 50(–80) cm tall, sparsely branched, at least to 5 times dichotomous. Shoots homophyllous or gradually slightly reduced in terminal divisions, almost equally thick throughout, ca. 13–25 mm in diam. incl. leaves or tapering to 10–15 mm, sporangiate usually from approx. 15–30 cm above the stem base and upward. Stems excl. leaves 2–4 mm thick (dried) at the base, sometimes tapering to ca. 1.5 mm upward. Leaves borne in more or less regular, often oblique, alternating whorls of (5–)6–7, these 1–2 mm apart, forming (10–)12–14 indistinct longitudinal ranks, spreading to ascending, slightly to strongly recurved from an ascending leaf base, linear to linear-lanceolate, widest just above the base, usually terminating in a short, very thin, whip-like, yellowish or brownish, usually strongly curved or twisted tip, (5–)7–14 × (0.8–) 1.2 mm, adaxially flat to somewhat concave (dried), abaxially with slightly tumid vein, usually somewhat lustrous, hypostomatic, with smooth margins.
