Friends of the Arboretum Native Plant Sale Osmunda cinnamomea – Cimmamon Fern COMMON NAME: Cinnamon Fern SCIENTIFIC NAME: Osmunda cinnamomea - The origin is uncertain, but might refer to the Saxon god Osmunder the Waterman, who hid his family in a clump of these ferns. And cinnamomea comes from the Latin for cinnamon, the color of the spores born on the fertile frond. REPRODUCTION: Bears its spores in late May. The spores are short lived. These spores are borne on a separate frond from the sterile “leaves.” SIZE: Large plant up to 5 feet tall. BEHAVIOR: Forms dense brush-like masses with a dozen or more groups of fronds growing from the crown. The fertile fronds are in the center. SITE REQUIREMENTS: Wet areas, marshes, thickets, wet fields, ditches. Likes muddy soil with pH 4 to slightly acid, pH 6.5. Prefers light shade. SPECIAL FEATURES: A very beautiful, tall, graceful fern. Fronds are bright green turning yellow and then bronze in the fall. In dense shade the fronds have pinkish stems. The fiddleheads are covered with dense white fuzz that later turns brown and falls off. Birds use this fuzz as nesting material. NATURAL RANGE: Throughout Wisconsin. From Newfoundland to Minnesota and south to the Gulf States. Varieties occur in tropical America and in eastern Asia. SUGGESTED CARE: Provide ample moisture, fine loamy soil, and light to moderate shade. COMPANION PLANTS: In boggy sites found with Goldthread, Spinulose Shield Fern, Winterberry, Royal Fern, Black Chokeberry, and Dewberry. At springs it is found with Marsh Marigold, Marsh Shield Fern, Boneset, Swamp Goldenrod and Skunk Cabbage. .

Growth of Fern Gametophytes After 20 Years of Storage in Liquid Nitrogen
FERN GAZ. 20(8): 337-346. 2018 337 GROWTH OF FERN GAMETOPHYTES AFTER 20 YEARS OF STORAGE IN LIQUID NITROGEN V. C. Pence Center for Conservation and Research of Endangered Wildlife (CREW) Cincinnati Zoo & Botanical Garden, 3400 Vine Street, Cincinnati, OH 45220, USA email: [email protected] Key words: cryopreservation, ex situ conservation, gametophyte; in vitro; long-term storage ABSTRACT In vitro grown gametophytes of six species of ferns, which had been cryopreserved using the encapsulation dehydration procedure, were evaluated for survival after 20 yrs of storage in liquid nitrogen. Tissues were rewarmed and transferred to a recovery medium with the same methods originally used to test pre-storage viability. All six species resumed growth. Post-storage viability was not consistently higher or lower than pre-storage viability of LN exposed tissues, likely reflecting the small sample sizes. However, these results demonstrate that long-term storage in liquid nitrogen is a viable option for preserving gametophytes of at least some fern species and could be utilized as an additional tool for preserving valuable gametophyte collections and for the ex situ conservation of fern biodiversity. INTRODUCTION For many species of ferns, gametophyte tissues have proven to be highly adaptable to growth in vitro (Table 1) . Most of these have been initiated through the aseptic germination of spores, although the aseptic germination of gemmae has also been demonstrated (Raine & Sheffield, 1997). As in vitro cultures, gametophytes can provide tissues for research and for propagation, both for ornamental ferns as well as for ferns of conservation concern. The ex situ conservation of ferns has traditionally relied on living collections and spore banks (Ballesteros, 2011).

(Received June 17, 1974; accepted for publication November 11, 1974) ABSTRACT Krassilov, V. A., 1975. Climatic changes in Eastern Asia as indicated by fossil floras. II. Late Cretaceous and Danian. Palaeogeogr., Palaeoclimatol., Palaeoecol., 17:157--172. Four Late Cretaceous phytoclimatic zones -- subtropical, warm--temperate, temperate and boreal -- are recognized in the Northern Hemisphere. Warm--temperate vegetation terminates at North Sakhalin and Vancouver Island. Floras of various phytoclimatic zones display parallel evolution in response to climatic changes, i.e., a temperature rise up to the Campanian interrupted by minor Coniacian cooling, and subsequent deterioration of cli- mate culminating in the Late Danian. Cooling episodes were accompanied by expansions of dicotyledons with platanoid leaves, whereas the entire-margined leaf proportion increased during climatic optima. The floristic succession was also influenced by tectonic events, such as orogenic and volcanic activity which commenced in Late Cenomanian--Turonian times. Major replacements of ecological dominants occurred at the Maastrichtian/Danian and Early/Late Danian boundaries. INTRODUCTION The principal approaches to the climatic interpretation of fossil floras have been outlined in my preceding paper (Krassilov, 1973a). So far as Late Creta- ceous floras are concerned, extrapolation (i.e. inferences from tolerance ranges of allied modern taxa) is gaining in importance and the entire/non-entire leaf type ratio is no less expressive than it is in Tertiary floras.

Plant Anatomy Lab 5
Plant Anatomy Lab 7 - Stems II This exercise continues the previous lab in studying primary growth in the stem. We will be looking at stems from a number of different plant species, and emphasize (1) the variety of stem tissue patterns, (2) stele types and the location of vascular tissues, (3) the development of the stem from meristem activity, and (4) the production of xylem and phloem by the procambium. All of the species studied are pictured either in your text or the atlases at the front of the lab. 1) Early vascular plants (cryptogams) A) Obtain a piece of the rachis of the fern (collected in the White Hall atrium). This structure is superficially analogous to a stem, although it has a different origin. Prepare a transverse section of the rachis and stain it in toluidine blue. Note the large amount of cortical tissue and the presence of sclerenchyma cells near the outer cortex. Also note that the stele vascular tissue appears to be amphiphloic. Lastly, you should be able to see readily the endodermal-style thickenings on the cells just outside each vascular bundle. B) Find prepared slides of the Osmunda and Polypodium (fern) rhizomes. Note the amphiphloic bundles (a protostele?), the presence of sclerenchyma in the cortex, and the thickened walls of the endodermis that you will find is not uncommon among many non-seed plants. Remember that rhizomes are modified stems that often occur underground. Osmunda fern vascular bundle. C) Obtain a prepared slide of Psilotum. This stele does not have a pith, so it is a protostele (or an actinostele because it has a star-like shape).

Kasey Hartz Natural Area Reference Sheet Osmunda Cinnamomea Cinnamon Fern
Kasey Hartz Natural Area Reference Sheet Osmunda cinnamomea Cinnamon Fern Osmundaceae (Royal fern family) Blooming season: No flower but plant emerges in spring. Plant: A perennial plant that actively grows from spring to fall. Stipes are 10-20 cm long. They are pink to reddish brown with wooly hairs covering the stipe. The average mature height can reach 1.5 m. The rhizomes are ascending to creeping and form a large, vase like base. The minimum root depth is 30 cm. Leaves: Fronds appear as brownish-green fiddleheads covered with rusty wool in early spring. The fronds are dimorphic. The fertile fronds appear before the sterile fronds and look like a cinnamon stick, but are shorter than the sterile fronds. Oblong in shape; 15-45 cm long and 2-3 cm wide. 8-25 pairs of tripinnate, opposite oblong pinnae with groupings of brown sporangia. Sterile fronds are green, bipinnate, and form around the fertile ones. Elliptic in shape, 3-12 dm long, 13-30 cm wide, and acute at the tip. 15-25 opposite pinnae that have a tuft of red brown hair at the base of the pinna. Flower: No flower. Fruit: No fruit, but sporangia form spores on the fertile fronds. They are a brown cinnamon color. The spores mature May to June. Can be confused with: Royal fern because fronds have similar shapes, come from the same family, and both are typically found in the same area. Geographic range: Type specimen location: Creek Bed Habitat. State: Common throughout the whole of Michigan, but less common in the north.

Our results confirm those from earlier anatomical and single-gene (rbcL) studies that suggested Osmunda s.l. is paraphyletic. Osmunda cinnamomea is sister to the remainder of Osmundaceae (Leptopteris, Todea, and Osmunda s.s.). We support the recognition of a monotypic fourth genus, Osmundastrum, to reflect these results. We also resolve subgeneric relationships within Osmunda s.s. and find that subg. Claytosmunda is strongly supported as sister to the rest of Osmunda. A stable, well-supported classification for extant Osmundaceae is proposed, along with a key to all genera and subgenera. Keywords—ferns, Osmunda, Osmundaceae, Osmundastrum, paraphyly, plastid DNA.

Appendix: Orchid Potting Mixtures - an Abridged Historical Review 1
Appendix: Orchid potting mixtures - An abridged historical review 1 T. J. SHEEHAN Introduction There is little doubt that potting media development over time has been the salvation of orchid growers (Bomba, 1975). When epiphytic orchids were first introduced into England and other European countries in the 18th century growers could not envision plants growing in anything but soil. '"Peat and loam' were good for everything and frequently became the mass murderers of the first generation of epiphytic orchids," Hooker is believed to have said around the end of the 19th century; England had become the graveyard of tropical orchids. Undoubtedly this was in reference to the concern individuals were having over the potting media problems. This problem also drew the attention of such noted individuals as John Lindley and Sir Joseph Paxton, as well as the Gardener's Chronicle, who noted that "The Rule of Thumb" had nothing to say about orchid growing; it was only effective in orchid killing (Bomba 1975). Fortunately, the ingenuity of growers solved the problem as innovative potting mixes evolved over the years. After visiting a number of orchid growing establishments it immediately becomes obvious to any orchid grower, professional or hobbyist, that orchids, both epiphytic and terrestrial, will grow in a wide variety of media. It has often been stated that epiphytic orchids can be grown in any medium except soil as long as watering and fertilization are adjusted to fit the mix being used. Ter restrial orchids seem to thrive in any medium that contains 40% or more organic matter. Reading cultural recommendations from the early days of orchid growing is most interesting and highly recommended.

Osmunda Pulchella Sp. Nov. from the Jurassic of Sweden
Bomfleur et al. BMC Evolutionary Biology (2015) 15:126 DOI 10.1186/s12862-015-0400-7 RESEARCH ARTICLE Open Access Osmunda pulchella sp. nov. from the Jurassic of Sweden—reconciling molecular and fossil evidence in the phylogeny of modern royal ferns (Osmundaceae) Benjamin Bomfleur1*, Guido W. Grimm1,2 and Stephen McLoughlin1 Abstract Background: The classification of royal ferns (Osmundaceae) has long remained controversial. Recent molecular phylogenies indicate that Osmunda is paraphyletic and needs to be separated into Osmundastrum and Osmunda s.str. Here, however, we describe an exquisitely preserved Jurassic Osmunda rhizome (O. pulchella sp. nov.) that combines diagnostic features of both Osmundastrum and Osmunda, calling molecular evidence for paraphyly into question. We assembled a new morphological matrix based on rhizome anatomy, and used network analyses to establish phylogenetic relationships between fossil and extant members of modern Osmundaceae. We re-analysed the original molecular data to evaluate root-placement support. Finally, we integrated morphological and molecular data-sets using the evolutionary placement algorithm. Results: Osmunda pulchella and five additional Jurassic rhizome species show anatomical character suites intermediate between Osmundastrum and Osmunda. Molecular evidence for paraphyly is ambiguous: a previously unrecognized signal from spacer sequences favours an alternative root placement that would resolve Osmunda s.l. as monophyletic. Our evolutionary placement analysis identifies fossil species as probable ancestral members of modern genera and subgenera, which accords with recent evidence from Bayesian dating. Conclusions: Osmunda pulchella is likely a precursor of the Osmundastrum lineage. The recently proposed root placement in Osmundaceae—based solely on molecular data—stems from possibly misinformative outgroup signals in rbcL and atpA genes.

Phytochrome Diversity in Green Plants and the Origin of Canonical Plant Phytochromes
ARTICLE Received 25 Feb 2015 | Accepted 19 Jun 2015 | Published 28 Jul 2015 DOI: 10.1038/ncomms8852 OPEN Phytochrome diversity in green plants and the origin of canonical plant phytochromes Fay-Wei Li1, Michael Melkonian2, Carl J. Rothfels3, Juan Carlos Villarreal4, Dennis W. Stevenson5, Sean W. Graham6, Gane Ka-Shu Wong7,8,9, Kathleen M. Pryer1 & Sarah Mathews10,w Phytochromes are red/far-red photoreceptors that play essential roles in diverse plant morphogenetic and physiological responses to light. Despite their functional signiﬁcance, phytochrome diversity and evolution across photosynthetic eukaryotes remain poorly understood. Using newly available transcriptomic and genomic data we show that canonical plant phytochromes originated in a common ancestor of streptophytes (charophyte algae and land plants). Phytochromes in charophyte algae are structurally diverse, including canonical and non-canonical forms, whereas in land plants, phytochrome structure is highly conserved. Liverworts, hornworts and Selaginella apparently possess a single phytochrome, whereas independent gene duplications occurred within mosses, lycopods, ferns and seed plants, leading to diverse phytochrome families in these clades. Surprisingly, the phytochrome portions of algal and land plant neochromes, a chimera of phytochrome and phototropin, appear to share a common origin. Our results reveal novel phytochrome clades and establish the basis for understanding phytochrome functional evolution in land plants and their algal relatives. 1 Department of Biology, Duke University, Durham, North Carolina 27708, USA. 2 Botany Department, Cologne Biocenter, University of Cologne, 50674 Cologne, Germany. 3 University Herbarium and Department of Integrative Biology, University of California, Berkeley, California 94720, USA. 4 Royal Botanic Gardens Edinburgh, Edinburgh EH3 5LR, UK. 5 New York Botanical Garden, Bronx, New York 10458, USA.
