Zusammenfassung: | Summary
The Winteraceae comprise 100 – 130 species in five to nine genera. The genus
Zygogynum
is currently thought to have a Papuasian-Pacific distribution and is only known from the western Pacific islands (New Caledonia, Vanuatu and the Solomon Islands), Australia and New Guinea, including the far western Bird’s Head Peninsula, but is not yet recorded from islands to the west of the Sahul Plate and the biogeographic boundary of Lydekker’s Line. Here, two new species of
Zygogynum
are described from west of both Wallace’s and Lydekker’s Lines.
Zygogynum moluccanum
is described from the Moluccan islands of Indonesia, and
Z. sundaicum
, a new species and generic record for the Sunda shelf, is described from the northern part of the Malaysian State of Sarawak in Borneo. In addition to descriptions and illustrations of the new species, the generic delimitation, fossil record and potential dispersal agents of
Zygogynum
are discussed. |
