Lycopodium verticillatum L. f. , Suppl. Pl.: 448. 1782.

≡ Phlegmariurus verticillatus (L. f.) A.R. Field & Testo in Molec. Phylogenet. Evol. 94: 645 (2015). ( Lycopodiaceae )

Lectotypus (designated here): RÉUNION: “nº 12. Lycos des Bois de l’Isle de Bourbon ”, s.d., Commerson s.n. ( LINN-HS nº 1649.12.1 image seen ; isolecto-: MPU [ MPU1054548 ]!, SBT nº 1.2.2.94 image seen) .

Notes. – TARDIEU-BLOT (1971) mentioned the type as “ Maurice. Sonnerat in Herb. Thouin”. This cannot be accepted as an effective lectotypification as both the locality and collector are wrongly cited. BADRÉ (2002b), VERDCOURT (2005), ROUX (2009) and ROUX & COOPER-DRIVER (2016) cited this specimen at SBT as holotype but failed to indicate the term “ lectotype ”. Thus , none can be accepted as an effective lectotypification ( TURLAND et al., 2018: Art. 9.23). The original material carrying the epithet in Linnaeus f.’s hand “verticillatum” is in LINN-HS [LINN-HS nº 1649.12.1] and designated here as lectotype. Its identity agrees with the current usage of the name.

Two duplicates of this original material are extant in MPU [MPU1054548] and SBT [SBT nº 1.2.2.94].

Phlegmariurus verticillatus is known in continental Africa from South Africa to Zambia and in Cameroun and São Tomé and Príncipe, the Comoro islands, Réunion, and Madagascar ( BADRÉ, 2002b).
