Basionym: Lycopodium pseudovarium Brownlie (1969: 23 , t.1, f.13-15). Synonym: Huperzia pseudovaria (Brownlie) Holub (1991: 93) . Type :— New Caledonia . Prov. Sud: Mont Humboldt , 1200 m , February 1872 , B . Balansa 3558 ( holotype P [ P00523013 !]) . Notes:—Following the classification proposed by Field et al. (2016) and later retained by PPG I (2016), this species formerly placed in Huperzia Bernhardi (1801: 126) belongs in Phlegmariurus Holub (1964: 21) . It is endemic to New Caledonia , but may possibly also occur in French Polynesia according to recent observations ( J . Nitta, pers. com.). The type at P was determined in 2015 by A . Field as Phlegmariurus varius ( Brown 1810: 165 ) A.R. Field & Bostock (2013: 49) due to the lack of the combination P. pseudovarius , and because he thought it may be a synonym of Phlegmariurus varius . More recent work provides evidence supporting P. pseudovarius as distinct, along with at least two other species in this complex (Field, unpublished data).
