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.
