Staghorn Fern - Platycerium Bifurcatum Platycerium Bifurcatum Is an Amazing Fern That Is Native to Eastern Australia
Staghorn Fern - Platycerium bifurcatum Platycerium bifurcatum is an amazing fern that is native to eastern Australia. It is one of eighteen species in the Platycerium genus, all of whom share a very dramatic, sculptural style. At first glance, most observers would not recognize these plants as ferns at all, since they are anything but ferny! Instead, the fronds of these beautiful, silvery green stunners resemble the antlers of elk or deer, which is why they have earned the common name of Staghorn or Elkhorn Fern. The resemblance is only heightened by the fact that they are epiphytes and grow outwards as if a large buck had left his rack hanging there. Platycerium bifurctum can easily be grown outdoors in subtropical gardens, but here in St. Louis we can imitate their native environment by mounting them on wooden plaques that can be brought indoors once the temperatures begin to cool. These plaques make striking decorations for a porch or patio. Learn how to craft your own on the next page. a few words on the anatomy of a staghorn • Staghorn ferns are epiphytes, clinging and growing vertically on tall trees or rock surfaces. They derive moisture and nutrients from the air and rain, supplemented by the plant debris that accumulates around their anchoring structures. • While the anchors for most epiphytes (such as orchids and bromeliads) are aerial roots or rhizomes, staghorn ferns add a covering layer of thick, spongy fronds that make a basket or inverted plate-like structure over the short, creeping rhizomes, providing a rooting media for the arching foliage fronds. -
Monilophyte Mitochondrial Rps1 Genes Carry a Unique Group II Intron That Likely Originated from an Ancient Paralog in Rpl2
Downloaded from rnajournal.cshlp.org on September 26, 2021 - Published by Cold Spring Harbor Laboratory Press Monilophyte mitochondrial rps1 genes carry a unique group II intron that likely originated from an ancient paralog in rpl2 NILS KNIE, FELIX GREWE,1 and VOLKER KNOOP Abteilung Molekulare Evolution, IZMB–Institut für Zelluläre und Molekulare Botanik, Universität Bonn, D-53115 Bonn, Germany ABSTRACT Intron patterns in plant mitochondrial genomes differ significantly between the major land plant clades. We here report on a new, clade-specific group II intron in the rps1 gene of monilophytes (ferns). This intron, rps1i25g2, is strikingly similar to rpl2i846g2 previously identified in the mitochondrial rpl2 gene of seed plants, ferns, and the lycophyte Phlegmariurus squarrosus. Although mitochondrial ribosomal protein genes are frequently subject to endosymbiotic gene transfer among plants, we could retrieve the mitochondrial rps1 gene in a taxonomically wide sampling of 44 monilophyte taxa including basal lineages such as the Ophioglossales, Psilotales, and Marattiales with the only exception being the Equisetales (horsetails). Introns rps1i25g2 and rpl2i846g2 were likewise consistently present with only two exceptions: Intron rps1i25g2 is lost in the genus Ophioglossum and intron rpl2i846g2 is lost in Equisetum bogotense. Both intron sequences are moderately affected by RNA editing. The unprecedented primary and secondary structure similarity of rps1i25g2 and rpl2i846g2 suggests an ancient retrotransposition event copying rpl2i846g2 into rps1, for which we suggest a model. Our phylogenetic analysis adding the new rps1 locus to a previous data set is fully congruent with recent insights on monilophyte phylogeny and further supports a sister relationship of Gleicheniales and Hymenophyllales. Keywords: group II intron; RNA editing; intron transfer; reverse splicing; intron loss; monilophyte phylogeny INTRODUCTION and accordingly the genome sizes of most free-living bacteria, are an example for the latter (Ward et al. -

In ferns, phytochrome mechanism responsible for the response to changes in the value of R/FR differs from the mechanism observed in spermatophytes. This study analyzed the course of ontogenesis of nest leaves in P. bifurcatum at two values of the R/FR ratio, corresponding to shadow conditions (low R/FR) and intense insolation (high R/FR). The work used only non-destructive research analysis, such as measurements of reflectance of radiation from the leaves, their blue-green and red fluorescence, and the chlorophyll a fluorescence kinetics. This allowed tracing the development and aging processes in the same leaves. Nest leaves are characterized by short, intense growth and rapid senescence. The study identified four stages of development of the studied leaves related to morphological and anatomical structure and changing photochemical efficiency of PSII. Under the high R/FR ratio, the rate of ontogenesis of the leaf lamina was much slower than under the low R/FR value. As shown, the rapid aging of the leaves was correlated with faster decline of the chlorophyll content. -

Harvest of Various Native Plant Species from Tasmania
Wildlife Trade Operation - Harvest of various native plant species from Tasmania ------------------------------------------------------------------------------------------------------- 1. Introduction This application is for the harvest of cut foliage for export of flora from state forest areas and private land in Tasmania and Flinders Island. The harvest operation is being monitored by Forestry Tasmania, and management of native species in Tasmania is carried out by the department of Primary Industries and Water. Legislative power to declare protected plants species is found under the Nature Conservation Act 2002. Other relevant legislation includes the Threatened Species Protection Act 1995, and the Forest Practices Act 1985. Scientific name Common name Harvest portion Banksia marginata Honeysuckle Banksia Flowering stems (Proteaceae) Blechnum nudum Fish-bone fern Unblemished foliage (Blechnanaceae) Gahnia grandis Cutting grass Flowering stems (after (Cyperaceae) seed drop) Gleichenia dicarpa, G. Coral fern Unblemished foliage microphylla (Gleicheniaceae) Lomatia tinctoria Guitar plant Unblemished foliage (Proteaceae) Nothofagus cunninghamii Myrtle Beach Unblemished foliage (Fagaceae) Polystichum proliferum Mother shield fern Unblemished foliage (Aspidiaceae) Xanthorrhoea australis Grass tree Unblemished foliage (Xanthorroeaceae) Dicksonia antarctica Soft Tree-fern Unblemished foliage (Dicksoniaceae) Tasmannia lanceolata Pepper bush Unblemished foliage; (Winteraceae) Ripe fruit Location of Harvest All products are to be harvested from “Unrestricted Multiple Use” state forest areas in Tasmania (as defined by Forestry Tasmania), and privately owned land in Tasmania and Flinders Island, under property owner’s consent as and when required. The present location of harvesting is defined as per contract of Sale Agreement with Forestry Tasmania No. .1120 Prids 18707, 18767,18769,187770. Flinders Island has not been necessary, however if demand increases, Flinders Island may be required to be harvested. -
Ecology of Hard Beech (Nothofagus Truncata) in Southern Outlier Stands
A. F. MARK and W. G. LEE 97 Botany Department, University of Otago, P.O. Box 56, Dunedin, New Zealand. Botany Division, D.S.I.R., Private Bag, Dunedin, New Zealand. ECOLOGY OF HARD BEECH (NOTHOFAGUS TRUNCATA) IN SOUTHERN OUTLIER STANDS IN THE HAAST ECOLOGICAL DISTRICT, SOUTH WESTLAND, NEW ZEALAND Summary: Vegetation and habitat descriptions are given for sites that span the very limited environmental range of southern outlier stands of hard beech (Nothofagus truncata). These are on well-drained, north to northwest aspect slopes at 44 oS in South Westland, 260km south of the species' previously assumed southern limit. Size class distributions and diameter growth rates of hard beech stems indicate that it is competing effectively with podocarp and broadleaved species, including the two other beeches present. Of the three local species (mountain beech - N. solandri var. cliffortioides and silver beech - N. menziesii), only hard beech showed a significant relationship between stem diameter and age, though diameter growth rates were generally similar among the three species. The erratic distribution of the three local beech species in the Haast and adjacent Paringa Ecological Districts is discussed in relation to possible glacial refugia. The scientific and conservation values of the outlier stands are emphasised. Keywords: Nothofagus truncata; Nothofagus biogeography; hard beech forest; tree age-size relations; glacial refugia; South Westland, New Zealand.
