California's Native Ferns
CALIFORNIA’S NATIVE FERNS A survey of our most common ferns and fern relatives Native ferns come in many sizes and live in many habitats • Besides living in shady woodlands and forests, ferns occur in ponds, by streams, in vernal pools, in rock outcrops, and even in desert mountains • Ferns are identified by producing fiddleheads, the new coiled up fronds, in spring, and • Spring from underground stems called rhizomes, and • Produce spores on the backside of fronds in spore sacs, arranged in clusters called sori (singular sorus) Although ferns belong to families just like other plants, the families are often difficult to identify • Families include the brake-fern family (Pteridaceae), the polypody family (Polypodiaceae), the wood fern family (Dryopteridaceae), the blechnum fern family (Blechnaceae), and several others • We’ll study ferns according to their habitat, starting with species that live in shaded places, then moving on to rock ferns, and finally water ferns Ferns from moist shade such as redwood forests are sometimes evergreen, but also often winter dormant. Here you see the evergreen sword fern Polystichum munitum Note that sword fern has once-divided fronds. Other features include swordlike pinnae and round sori Sword fern forms a handsome coarse ground cover under redwoods and other coastal conifers A sword fern relative, Dudley’s shield fern (Polystichum dudleyi) differs by having twice-divided pinnae. Details of the sori are similar to sword fern Deer fern, Blechnum spicant, is a smaller fern than sword fern, living in constantly moist habitats Deer fern is identified by having separate and different looking sterile fronds and fertile fronds as seen in the previous image. -

This work uses metagenomic sequencing, for assessing the rhizosphere of the only reported terrestrial mangrove fern Acrostichum aureum Linn. from the Indian Sunderbans. Targeted sequencing of the V3 - V4 region using Illumina Hiseq was performed and the analyses of the sequenced files revealed the presence of a wide variety of microbial members with the highest belonging to Proteobacteria superphyla. We believe that this is the first phylogenetic assessment of the Fern rhizosphere and should provide us with valuable insights into the quality of microbial assemblage available in this particular niche.

A Diploids-First Approach to Species Delimitation and Interpreting Polyploid Evolution in the Fern Genus Astrolepis (Pteridaceae)

Box 299, St. Louis, Missouri 63166 U. S. A. 3 Author for correspondence ( [email protected] ) Communicating Editor: Javier Francisco-Ortega Abstract— Polyploidy presents a challenge to those wishing to delimit the species within a group and reconstruct the phylogenetic relation- ships among these taxa. A clear understanding of the tree-like relationships among the diploid species can provide a framework upon which to reconstruct the reticulate events that gave rise to the polyploid lineages. In this study we apply this “diploids-first” strategy to the fern genus Astrolepis (Pteridaceae). Diploids are identified using the number of spores per sporangium and spore size. Analyses of plastid and low-copy nuclear sequence data provide well-supported estimates of phylogenetic relationships, including strong evidence for two morphologically distinctive diploid lineages not recognized in recent treatments. One of these corresponds to the type of Notholaena deltoidea , a species that has not been recognized in any modern treatment of Astrolepis . This species is resurrected here as the new combination Astrolepis deltoidea . The second novel lineage is that of a diploid initially hypothesized to exist by molecular and morphological characteristics of several established Astrolepis allopolyploids. -

Genetic Differentiation and Polyploid Formation Within the Cryptogramma Crispa Complex (Polypodiales: Pteridaceae)

R.Br. ex Hook. is distributed across alpine and high latitude regions of Europe and western Asia and is sympatric with the recently described octoploid C. bithynica S.Jess., L.Lehm. & Bujnoch in north-central Turkey. Our analysis of a 6-region plastid DNA sequence dataset comprising 39 accessions of Cryptogramma R.Br., including 14 accessions of C. crispa and one accession of C. bithynica, revealed a deep genetic division between the accessions of C. crispa from western, northern, and central Europe and the accessions of C. crispa and C. bithynica from Turkey and the Caucasus Mountains. This legacy likely results from Pleistocene climate fluctuations and appears to represent incipient speciation between the eastern and western clades. These plastid DNA sequence data also demonstrate that the western clade of C. crispa, specifically the western Asian clade, is the maternal progenitor of C. bithynica. Our analysis of DNA sequence data from the biparentally inherited nuclear locus gapCp supports an autopolyploid origin of C. bithynica, with C. crispa as the sole progenitor.

O. Chidambaram College, Tuticorin – 628008, Tamil Nadu, India. Abstract The physicochemical parameters are mainly used in judging the purity of the drug. Hence, in the present investigation, moisture content, total ash, water-soluble ash, acid-soluble ash, sulphated ash and different solvent extractive values are determined. Preliminary screening of phytochemicals is a valuable step, in the detection of the bioactive principles present in medicinal plants and subsequently, may lead to drug discovery and development. In the present study, chief phytoconstituents of the Acrostichum aureum L (Fern) medicinal plant of the Pteridaceae family were identified to relate their presence with bioactivities of the plants. These research findings highlight that methanolic extracts of A. aureum leaves had the highest number of phytochemicals compared to other solvent extracts. Hence, methanolic extracts of A. aureum leaves holds the great potential to treat various human diseases and has profound medical applicability. Fluorescence analysis of powder under visible light and UV light helps establish the purity of the drug. Hence, fluorescence analysis of leaf powder is undertaken.

Species Relationships and Farina Evolution in the Cheilanthoid Fern

A. 2 Missouri Botanical Garden, P.O. Box 299, St. Louis, Missouri 63166 U. S. A. 3 Author for correspondence ( [email protected] ) Communicating Editor: Lynn Bohs Abstract— Convergent evolution driven by adaptation to arid habitats has made it difficult to identify monophyletic taxa in the cheilanthoid ferns. Dependence on distinctive, but potentially homoplastic characters, to define major clades has resulted in a taxonomic conundrum: all of the largest cheilanthoid genera have been shown to be polyphyletic. Here we reconstruct the first comprehensive phylogeny of the strictly New World cheilanthoid genus Argyrochosma . We use our reconstruction to examine the evolution of farina (powdery leaf deposits), which has played a prominent role in the circumscription of cheilanthoid genera. Our data indicate that Argyrochosma comprises two major monophyletic groups: one exclusively non-farinose and the other primarily farinose. Within the latter group, there has been at least one evolutionary reversal (loss) of farina and the development of major chemical variants that characterize specific clades. Our phylogenetic hypothesis, in combination with spore data and chromosome counts, also provides a critical context for addressing the prevalence of polyploidy and apomixis within the genus. Evidence from these datasets provides testable hypotheses regarding reticulate evolution and suggests the presence of several previ- ously undetected taxa of Argyrochosma. -

We have been fortunate in securing for this meeting the leader of the Grevillea Study Group Mr. Peter Olde. We will meet at 10.30am at the Eurobodalla Regional Botanic Gardens Princes Highway, about 5km south of Batemans Bay After Peter’s presentation, and lunch at the Gardens, we will travel to Moruya for a look at some Grevilleas growing at Mark and Carolyn Noake’s garden, and then participate in a practical propagation session. Please bring morning tea and lunch. Those wishing to do so may purchase lunch from the Chefs Cap Café at the gardens. As we will walk around the Noake garden, comfortable walking shoes and a hat are advisable. There is plenty of seating at the ERBG, but you will need to put in a chair for use at Mark and Carolyn’s. See page 2 for details of these activities Future activities Due to Easter falling in the first week of April, the committee is discussing whether the April walk will be deferred till the 11th,. More on this next newsletter Our next meeting on May 2nd, is another treat for members. We will have to travel a bit, but Fern expert Kylie Stocks will let us in on the secrets of growing ferns successfully.
