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.

New Combinations in Struthiopteris Spicant for the European Flora

During the last decade, evidence has been accumulating about the polyphyletism within Blechnum Linnaeus (1753: 1077) (e.g. Shepherd et al. 2007, Rothfels et al. 2012, Gabriel y Galán et al. 2013, Perrie et al. 2014). Recent molecular studies (Gasper et al. 2016a) lead to an updated classification attempting to put morphological characters into a natural, phylogenetic relation (Gasper et al. 2016b). Because of these changes, the species most people associate with the genus Blechnum, B. spicant (Linnaeus 1753: 1066) Roth (1794: 56), is now treated under Struthiopteris Scopoli (1754: 25). Struthiopteris spicant (L.) F.W.Weiss (1770: 287), a widely distributed plant in the Northern Hemisphere, is characterized by having strongly dimorphic fronds (Lawalrée 1964), but it shows certain morphological variability that has led to the recognition of several forms, which have been taxonomically treated in several ways, the varietal rank being the currently accepted.

Ferns of the National Forests in Alaska
Ferns of the National Forests in Alaska United States Forest Service R10-RG-182 Department of Alaska Region June 2010 Agriculture Ferns abound in Alaska’s two national forests, the Chugach and the Tongass, which are situated on the southcentral and southeastern coast respectively. These forests contain myriad habitats where ferns thrive. Most showy are the ferns occupying the forest floor of temperate rainforest habitats. However, ferns grow in nearly all non-forested habitats such as beach meadows, wet meadows, alpine meadows, high alpine, and talus slopes. The cool, wet climate highly influenced by the Pacific Ocean creates ideal growing conditions for ferns. In the past, ferns had been loosely grouped with other spore-bearing vascular plants, often called “fern allies.” Recent genetic studies reveal surprises about the relationships among ferns and fern allies. First, ferns appear to be closely related to horsetails; in fact these plants are now grouped as ferns. Second, plants commonly called fern allies (club-mosses, spike-mosses and quillworts) are not at all related to the ferns. General relationships among members of the plant kingdom are shown in the diagram below. Ferns & Horsetails Flowering Plants Conifers Club-mosses, Spike-mosses & Quillworts Mosses & Liverworts Thirty of the fifty-four ferns and horsetails known to grow in Alaska’s national forests are described and pictured in this brochure.

Rothfels and Michael A. Sundue contributed equally to this work. Author for correspondence: Carl J. Rothfels, [email protected] Abstract We present a family-level classification for the eupolypod II clade of leptosporangiate ferns, one of the two major lineages within the Eupolypods, and one of the few parts of the fern tree of life where family-level relationships were not well understood at the time of publication of the 2006 fern classification by Smith & al. Comprising over 2500 species, the composition and particularly the relationships among the major clades of this group have historically been contentious and defied phylogenetic resolution until very recently.

Compared to seed plants, the diversity patterns of ferns have been poorly studied along disturbance gradients, including aspects of their taxonomic, phylogenetic, and functional diversity. Longnan County, a biodiversity hotspot in the subtropical zone in South China, was selected to obtain a more thorough picture of the fern–disturbance relationship, in particular, the taxonomic, phylogenetic, and functional diversity of ferns at different levels of disturbance. In 90 sample plots of 5 5 m2 along roadsides × at three sites, we recorded a total of 20 families, 50 genera, and 99 species of ferns, as well as 9759 individual ferns. The sample coverage curve indicated that the sampling effort was sufficient for biodiversity analysis. In general, the taxonomic, phylogenetic, and functional diversity measured by Hill numbers of order q = 0–3 indicated that the fern diversity in Longnan County was largely influenced by the level of human disturbance, which supports the ‘increasing disturbance hypothesis’.

Doodia Hindii ( Blechnaceae) a New Species from North Eastern New South Wales, Australia
Telopea 12(2) 257–261 Doodia hindii ( Blechnaceae) a new species from north eastern New South Wales, Australia T. Carrick Chambers National Herbarium of NSW, Mrs Macquaries Road, Sydney, NSW 2000, Australia Email: [email protected] Abstract Doodia hindii Tindale ex T.C.Chambers is described for the first time. This is a rarely collected species from rainforest in mountain regions of north eastern New South Wales, bringing to nine the number of species of Doodia in Australia . Introduction The genus Doodia (Blechnaceae) is estimated to contain more than 30 species distributed through Australasia, Papuasia, Malesia, Sri Lanka and the Pacific region extending north east to Hawaii and as far east as Easter Island (Parris 1972, 1998). Hybrids have been reported among some of the species especially in the D. caudata complex (Andrews 1990). Eight species have been defined by Parris (1998) in the Flora of Australia treatment. By modifying the key provided there, this additional (ninth) Australian taxon can be accommodated as follows (modifications are in italics): 4: Numerous strongly reduced basal pinnae/segments present; abaxial surface of pinnae/segments mid vein either with or without tubercles .............................................................................. 5 5 Rhizome erect, forming caudex up to 30 cm ................................................ 1.

Blechnum Spicant Joe Sime
THE NEWSLETTER OF THE SHADE AND WOODLAND PLANTS GROUP February 2019 Plant of the Month: Blechnum spicant Joe Sime It is at this time of the year when the truly evergreen ferns come into their own, and one of the best of these is Blechnum spicant. This is a widespread species occurring in western North America, N.E. Asia and Europe. It is known as the deer fern or the hard fern. Like other members of the genus it produces two types of fronds: low growing, green sterile fronds about 18 ins long that form a bright mat at this time of the year and are shown in the photo, and taller (up to 3 ft) upright, fertile fronds growing from the centre of the clump. Once the spores are cast in early autumn these die back, and can be trimmed off if you are a tidy gardener. It is a trouble free plant accepting any spot in full or part shade, although it would like some moisture occasionally. The one shown is by a path at the foot of a young oak tree. They are said to divide easily (I have not tried) and to grow quite well from spore. And if you are hungry, the North American Indians used to eat the roots and make tea from the fronds! Epimedium (a love affair!) Colin Moat It’s always quite interesting when putting together a piece like this to hark back to when you first became attracted to the plant you are writing about. It happened probably more than 20 years ago at a plant fair, and I was wowed by seeing a fabulous display offered by Europa Nursery (then based in London but they moved to Devon, and, I believe, closed their nursery).
