Horizontal stems flat on ground, 4–17 × 0.3–0.8 cm, stems (excluding leaves) thick, 1–1.5 mm diam.; leaves monomorphic, vertically ascending, further ascending when dry, 4–6 × 0.8–1 mm, marginal teeth absent. Upright shoots 1, 9–13 × 0.4–0.5 cm; strobilus 1/5–1/3(–1/2) total length; leaves strongly appressed, 3.5–6 × 0.3–0.8 mm, marginal teeth absent. Strobili 20–40 × 4–8 mm. Sporophylls appressed, 3–4 × 0.2–0.5 mm, marginal teeth absent. 2n = 312.


Habitat: Wet, acidic ditches and borrow pits
Elevation: 0–200 m

Discussion

The distinctive Lycopodiella subappressa and L. margueriteae are sexual polyploids. The full geographic distribution of L. subappressa is still unknown.

Of conservation concern.
