“…While, Blechnum orientale L. had least genetic similarity index of 1.00 per cent. This could have happened due to highly heterozygous nature of this crop similar results were observed by and Perrie et al, (2003) in New Zealand fern and Kumar et al, 2016…”

In view of the high level of morphological diversity in fern species, assessment of genetic variation among 19 fern species was evaluated using ten inter simple sequence repeat (ISSR) markers. The results suggested that the ISSR markers produced much better reproducible bands and were more efficient in grouping fern species. ISSR fragments generated 29 to 87 bands per primer. A total of 281 polymorphic bands generated 34.48 to 66.66 per cent polymorphism per primer. All germplasm were clearly differentiated by their ISSR fingerprints. The similarity coefficient on ISSR profiles were subjected to UPGMA cluster analysis between the species was within the range from 1.00 to 25 per cent. The dendrogram generated by ISSR markers revealed two major clusters, indicating that fern species have distributed based on frond shape, frond type, type of rhizome, habitat, stipe colour, texture, sori position. This is the first report in ferns genetic diversity estimation and clustering by using ISSRs.

“…On the other hand, recurrent LDD, as demonstrated here in A. hookerianum , may result in sufficient gene flow to overcome the genetic differentiation of populations from the Chatham Islands and the mainland in at least some species. For instance, Perrie et al. (2003) could not differentiate mainland and morphologically‐divergent Chatham Islands’ populations of the fern Polystichum vestitum with amplified fragment length polymorphism (AFLP) DNA‐fingerprinting; they suggested that the high genetic diversity of the population of the Chatham Islands might be the product of recurrent gene flow from genetically heterogeneous mainland populations, but the evidence was not definitive.…”

Aim It is well established that many groups of plants and animals have undergone long‐distance dispersal, but the extent to which this continues beyond initial colonization is largely unknown. To provide further insight into the frequency of gene flow mediated by long‐distance dispersal, we investigated the origins of the fern Asplenium hookerianum on the Chatham Islands, and present a review of the contribution of molecular data to elucidating the origins of this archipelago’s biota. Location Chatham Islands and New Zealand. A. hookerianum is scarce on the Chatham Islands but common in New Zealand, some 800 km to the west. Methods We compared chloroplast trnL–trnF DNA sequence data from Chatham Islands’A. hookerianum with extensive phylogeographic data for this genetically variable species in mainland New Zealand. Results Our sequencing revealed the presence of two haplotypes in Chatham Islands’A. hookerianum. These haplotypes differed by four mutational events and were each more closely related to haplotypes found in New Zealand than to each other. Main conclusions Despite the rarity of A. hookerianum on the Chatham Islands, its populations there appear to derive from at least two long‐distance dispersal events from New Zealand, these possibly originating from different areas. We suggest that long‐distance transoceanic dispersal, and the gene flow it can mediate, may be more common than is generally appreciated.

“…Polystichum vestitum is endemic and widespread throughout the New Zealand botanical region. It is morphologically highly variable, but molecular data does not support classifi cation at the varietal level (Perrie et al 2003 17.5-27(-34) × (13-)15.5- 21.5 µm, obovoideae, ellipsoideae vel subglobosae, saepe angulatae, interne hyalinae, membrana ca. 0.5 µm crassa hyalina verrucosa, poris germinationis ignotis.…”
