6.­­­ Phlegmariurus chiricanus ­­­(Maxon) B. Øllgaard (2012b: 13) . Fig. 5 Lycopodium chiricanum Maxon (1913: 176).— Urostachys chiricanus (Maxon) Nessel (1939: 45).— Huperzia chiricana (Maxon) Holub (1985: 71). Type:— PANAMA: Upper belt and summit of Chiriquí Volcano, 3025—3374 m elev., rocky slope, Maxon 5364 (US 675719 holotype; MO, NY, BONN-Nessel 56, fragment isotypes). Erect from an ascending base, tufted, 8–12 cm tall. Shoots homophyllous, equally thick throughout, 6–8 mm in diam. incl. leaves. Leaves uniform throughout, densely crowded, borne in irregular, alternating whorls of 5–6, these 1.5–2 mm apart, closely imbricate, narrowly oblong to lanceolate, 3.5–5 × ca. 1 mm, prominently decurrent, boat-shaped, with incurved tip, abaxially rounded and smooth, without blister-like epidermis cellls abaxially, with denticulateserrate, strongly sclerified, hyaline margins, yellowish green. Sporangia 1.5–1.7 mm wide. ­­­ Notes: Phlegmariurus chiricanus differs from Phlegmariurus crassus by the serrulate leaf margins and smooth epidermis. Indicated by Rojas (2005) from Volcán Turrialba in Costa Rica; we have examined material from this locality (Hauke 427, NY) and believe they likely correspond instead to small plants of Phlegmariurus talamancanus. Additional­­­specimen­­­examined:— Chiriquí: Llanura en la falda del cráter al S.O. de la torre del INTEL, Volcán Barú, 3474 m, Béliz & Correa 363 (PMA).Published as part of Øllgaard, Benjamin & Testo, Weston, 2021, --- The- -- Lycopodiaceae- -- of- -- Panamá, pp. 1-66 in Phytotaxa 526 (1) on page 12, DOI: 10.11646/phytotaxa.526.1.1, http://zenodo.org/record/572318
