11. Celmisia brevifolia Cockayne ex Cheeseman (1925: 938) .

Type:—NEW ZEALAND. South Island, Plateau of the Old Man Range in herb-moor, 1500 m. alt., 27 March 1919, L. Cockayne 1970 (lectotype K 77065 [image!] designated here; isolectotype WELT SP45774!).

Notes:— Cheeseman (1925) described C. brevifolia and cited several syntypes that include plants with quite different leaf appearances regarding shape and indumentum. Plants from the Old Man Range (L. Cockayne 1970, see typification) and some from Mt Pisa (L. Cockayne 1978, K 77064 [image!], WELT SP45775!, SP45776!), both in Central Otago, have leaves obovate and pseudopetiolate, upon which Allan (1961: 618) wrote: “Neither type locality nor type is indicated, but Central Otago plants included by Cheeseman are fairly uniform […]”. Another syntype from Mt. Pisa (SP46497!) and one collected at Mt Ernest in northwest Otago (AK 34925!) have leaves that vary from obovate, obovate-oblong, oblanceolate-oblong, to almost linear-oblong, approaching C. angustifolia . Additional syntypes (AK 9707!, 9708!, AK 9709!, 9710!, AK 9706!, WELT SP46498!) coming from the Two Thumb Range in South Canterbury, have a conspicuous white arachnoid indumentum covering most of the adaxial surface (note that the syntypes mentioned above and the typical C. angustifolia are glabrous on the adaxial surface) and leaves oblanceolate-oblong to linearoblong, almost identical to C. angustifolia from its typical area (Torlesse Range, see typification of C. angustifolia ).

Plants from the Old Man Range are quite uniform in leaf shape and are representative of the taxon commonly recognized as Celmisia brevifolia that occurs mainly in Central Otago ( Allan 1961, Mark & Adams 1973) as indicated above.Therefore, I have chosen the material from this locality (L. Cockayne 1970) as a lectotype. Besides, this specimen corresponds to a branch with leaves and one scape with a complete involucre, morphological features that allow its appropriate identification.

Cheeseman ascribed the name C. brevifolia to Cockayne, however, according to the ICN Art. 46.5 and 46.6 ( Turland et al. 2018), the author can be cited either as C. brevifolia Cheeseman or as C. brevifolia Cockayne ex Cheeseman.
