Abstract Relationships
of the three species of Microsorum occurring in
New Zealand, M. novae-zealandiae, M.
pustulatum, and M. scandens, were
explored using evidence from four chloroplast genomic markers: rbcL,
rps4, rps4–trnS
intergenic spacer, and trnL–F
intergenic spacer. All three species were nested in a
strongly supported lecanopteroid clade together with the ant-fern genus
Lecanopteris and several species accepted as
belonging to the polyphyletic genus Microsorum. M.
scandens is sister to M. varians from
New Caledonia, and in turn both are sister to M. linguiforme.
M. novae-zealandiae and M. pustulatum
form a clade together with the New Caledonian endemic M.
viellardii. Support from morphological features is discussed,
as is the possibility of a diversification of the lecanopteroids in
Eastern Malesia and/or adjacent areas to the south after the collision
of Australia and south-east Asia.
