Abstract Puccinellia Parl., saltgrass, of temperate
regions throughout the world, is revised for New Zealand. Four indigenous
species are recognised: P. stricta shared with Australia; and three
endemic species: P. raroflorens, described as new from salt pans in
Central Otago and one locality on Stewart I., P. macquariensis, and
P. walkeri, this last name being taken up for the species latterly known
in New Zealand as P. novae-zealandiae. Subantarctic Puccinellia
antipoda and P. chathamica are treated as subspecies within P.
walkeri.
Three naturalised species are recognised: P. distans from Eurasia,
P. fasciculata from North America and Europe, and P. rupestris
from Europe. Plants originally described as indigenous P.
scott-thomsonii were found to be sterile and are included within P.
fasciculata.
