Evidence for an allopolyploid complex in New Zealand Polystichum (Dryopteridaceae)
Cytological, morphological, and molecular analyses indicate that the fern previously known as Polystichum richardii constitutes an allopolyploid complex, in which four separate evolutionary lineages are present.
Spore morphology as a taxonomic data source in Cyathea J.E. Smith and Asplenium L.
A morphological assessment of Adiantum hispidulum Swartz and A. pubescens Schkuhr (Adiantaceae: Filicales) in New Zealand
This study shows that only those characters associated with the pinnule hairs can be used to consistently separate the two polymorphic members of the Adiantum hispidulum Swartz complex.
Biogeography of temperate Australasian Polystichum ferns as inferred from chloroplast sequence and AFLP
The extant diversity within New Zealand Polystichum appears to have been derived from a single, trans-oceanic dispersal event (within the last c. 20 Myr), followed by a relatively extensive in situ ecological radiation.
An Assessment of Pollen Morphology in the Genus Vitex L. (Labiatae)
Pollen grains of Vitex (Labiatae) a large pantropical genus with a few temperate species, are examined by light microscopy, SEM and TEM and the possible taxonomic significance of the morphological differences discussed is discussed.
The pollen of Dysoxylum (Meliaceae): the demise of Pseudocarapa
The majority of taxa release grains as tetra-colporate monads, but tetrads have previously only been known in Pseudocarapa and are also recorded here in three species of Dysoxylum.
Algal communities in phytotelmata: A comparison of native Collospermum and exotic bromeliads (Monocotyledonae) in New Zealand.
Forest-sourced bromeliad and Collospermum water held a comparatively less diverse range of biota, with a complete lack of algal presence, and it is proposed that the phytotelmic conditions are being unsuitable for algal growth.
Implications for selected indigenous fauna of Tiritiri Matangi of the establishment of Austropuccinia psidii (G. Winter) Beenken (myrtle rust) in northern New Zealand
Morphological and genetic diversity in the New Zealand fern Polystichum vestitum (Dryopteridaceae), with special reference to the Chatham Islands
Morphological similarities between some plants of P. vestitum from the Chatham Islands and some from the islands in the subantarctic and around Stewart Island are not reflected by a close genetic relationship, and it is suggested that these plants are retained as a single taxonomic species, with no subspecies.
