“…Desquamation of the perine was observed in Austroblechnum penna-marina, which gave it a foliose appearance, as also observed by Tryon & Lugardon (1990) and Coelho & Esteves (2008).…”

“…Passarelli et al (2010) cited microgranules for two species of Austroblechnum, but with a psilate perine. Coelho & Esteves (2008) also mentioned the Principal components analysis revealed the grouping of these species at the negative side of axis 1, demonstrating their similarity with regard to the quantitative data, with the exception of Austroblechnum divergens, which was located on the negative side of axis 2 and grouped with other genera because it had the highest value for LD (larger diameter).…”

“…The positions of these species along the multivariate axes were distinct, resulting from the higher equatorial diameter (DE) for L. plumieri, although they had the same values for larger diameter (LD). Coelho & Esteves (2008) analyzed Parablechnum proliferum, and classified the perine as micro-rugulate with projections, while Moran et al (2018) considered it as folded with filaments. The species of Parablechnum of the present study had a perine with crests and the presence of filaments with different degrees of intensity for each species, which differs from the ornamentation described in the studies cited above, agreeing only in the presence of filaments.…”

“…of the Itatiaia Plateau in the state of Rio de Janeiro, including five species of Blechnum. Coelho & Esteves (2008) analyzed seven species of Blechnaceae from the State Park of the Fontes do Ipiranga in the state of São Paulo, and highlighted the existence of a laminar surface on the spores, which they felt would be possessed by the entire family and thus differentiate it from all other ferns.…”

Spore diversity among species of Blechnaceae in the Atlantic Forest

et al. 2019

The palynological diversity of Blechnaceae in the Atlantic Forest was investigated. While the monophyletic family belongs to the group of leptosporangiate ferns, a new classification proposed by recent phylogenetic study reorganizes the family and adds new genera. To expand palynological knowledge of the group, the spore morphology of 23 species and a hybrid, distributed among 10 genera, was described. Material from herbarium collections were submitted to acetolysis and mounted on slides, with subsequent statistical analysis of spore measurements. Photomicrographs of the material were taken under both light and scanning electron microscopy. Perine ornamentation varied among psilate, rugulate and scabrate; granules and gemmae were present along with thin, smooth cristae. Species of Blechnum and Austroblechnum exhibited the greatest diversity. The attributes of the spores obtained here were able to differentiate the analyzed species, although the spore morphology of some taxa was found to be very similar. Multivariate analysis assessed the relevance of quantitative data for differentiating the taxa.
