Tc. Chambers et Pa. Farrant, THE BLECHNUM-PROCERUM (CAPENSE) (BLECHNACEAE) COMPLEX IN NEW-ZEALAND, New Zealand Journal of Botany, 36(1), 1998, pp. 1-19
There are four species of Blechnum in the B. procerum complex in New Z
ealand: B. procerum and three new species, B. novae-zelandiae, B. mont
anum, and B. triangularifolium. All three are distinct from the Austra
lian B. minus. The new species are endemic to New Zealand and have bee
n known as ''Kiokio'', ''Mountain kiokio'', and ''Green Bay kiokio'',
respectively, and variously but inconsistently referred to as B. capen
se, B. procerum, B. minor, B. minus, and Lomaria latifolia.
