≡Parmelia sinuosa (Sm.) Ach., Syn. Meth. Lich.: 207 (1814).
Descriptions : Flora (1985: 200). See also Elix (1994h: 58).
Chemistry : Cortex K−, KC+ yellow, UV−; medulla K+ yellow-red, C−, Pd−, UV−; containing usnic acid, salazinic acid (major), consalazinic acid (minor) and ±norstictic acid (tr.)
N: Northland to Wellington. S: Nelson to Fiordland. St: C: Widely distributed in lowland and/or coastal habitats of high humidity and moderate shade. A common epiphyte of divaricating shrubs, especially Discaria toumatou. A good indicator of humid habitats. Widespread, on all continents except Antarctica (Purvis et al. 1992; Nimis 1993; Santesson 1993; Esslinger & Egan 1995; Galloway & Quilhot 1999; Louwhoff & Elix 2002a; McCarthy 2003c, 2006; Nimis & Martellos 2003; Santesson et al. 2004).
