Lycopodiella matthewsii (Hook.) Holub (1983: 441) .— Fig. 4A .

Lycopodium matthewsii Hooker (1836 : t. 26). Type:— PERU; Bagasan, Matthews 1778 (K holotype!; isotype, BM!) .

Horizontal shoots appressed to the ground, firmly rooted with short intervals, bearing stiffly erect, dorsally arising, simple, strobiliferous branches. Horizontal shoots at least to 50 cm long, sparsely unequally branched in the horizontal plane, densely covered on all sides by almost uniform, somewhat upwardly secund, or spreading to perpendicular leaves, 10–18 mm wide incl. leaves; the leaves linear-lanceolate to subulate, flat, with smooth margins or with short to long slender diverging teeth, soft, light green, (5–) 7–10 × (0.5–) 0.8–1.2 mm. Erect peduncular branches ca. 8–15 mm in diam. incl. leaves, to 50 cm tall incl. the strobilus, its leaves radially arranged, borne in alternating whorls of (5–) 6–10, these 1.5–4 mm apart, forming (10–) 12–20 indistinct longitudinal ranks, usually concealing the stem like leaves of horizontal shoots, or narrower, appressed to ascending (rarely patent), with entire margins or with few to several long perpedicular to recurved teeth, to near the leaf apex. Mature strobili to 12 cm long, 12–20 mm in diam. incl. sporophylls. Mature sporophylls borne like peduncle leaves, narrowly lanceolate to lanceolate-caudate with a 1–1.5 mm wide subpeltate base and with several long, coarse, hooked teeth on margins (or sometimes smooth), usually gradually narrowed into a long tip, often with teeth to beyond the middle, 6–10 mm long. Sporangia axillary, subglobular, ca. 1–1.2 mm in diam., almost concealed by sporophyll bases.

Distribution: Andes from Venezuela to Peru.

Habitats: Lycopodiella matthewsii occurs at mid to high altitudes (1700–3750 m) most often in deeper, peaty, moist and less rapidly drained soils in low paramos and marshy places in the shrub forest zone.
