Abstract Field observations of the little known, New
Zealand endemic red alga Gelidium longipes (Gelidiales, Rhodophyta)
indicate that this species has a highly restricted distribution in northern
New Zealand. Prior to this work G. longipes had not been collected
for 50 years. This study located two closely situated and very small populations
in the Bay of Islands; extensive fieldwork in comparable sites to the north
and south of this region has not located any further sightings of this species.
Material housed in the Agardh herbarium, Lund, is designated as the lectotype
of this species and duplicate material is identified in New Zealand herbaria.
This is the second species of New Zealand endemic Gelidium that has
been found to have a very restricted distribution; G. allanii has
been reported previously from isolated and restricted populations in northern
Northland.
