Phytoestrogen emerged as a potential alternative of estrogen with minimum side effects. Green clover (Marsilea crenata Presl.) is a typical plant in East Java which suspected contains estrogen-like substances. The aim of this research was to report the phytochemical properties of M. crenata using GC-MS as a preliminary study. M. crenata leaves were dried and extracted with n-hexane, then separated using vacuum column chromatography to get four fractions, after that the n-hexane extract and four fractions were identified with GC-MS. The results of GC-MS analysis showed some compounds contained in M. crenata leaves like monoterpenoid, diterpenoid, fatty acid compounds, and other unknown compounds. The results obtained in this research indicated a promising potential of M. crenata as medicinal plants, especially as antiosteoporotic agent.

Marsilea Aegyptiaca (Marsileaceae) on the Mediterranean Island of Elafonisos (Laconia, Peloponnese, Greece)
FERN GAZ. 20(7): 293-300. 2018 293 MARSILEA AEGYPTIACA (MARSILEACEAE) ON THE MEDITERRANEAN ISLAND OF ELAFONISOS (LACONIA, PELOPONNESE, GREECE) Armin Jagel1 & Marcus Lubienski2 1 Danziger Str. 2, 44789 Bochum, Germany; [email protected] 2 Am Quambusch 25, 58135 Hagen, Germany; [email protected] Key Words: Marsilea aegyptiaca, Elafonisos, Greece, European species ABSTRACT The water-clover species Marsilea aegyptiaca was first detected on the Mediterranean island of Elafonisos (Peloponnese, Greece) nearly 25 years ago. This was the first record for the species as part of the European flora. Recent work has shown that M. aegyptiaca still occurs at the site, and data are presented concerning its identification, habitat and distribution. Morphological characters of all known European species within the genus are compared. INTRODUCTION Water-clovers (Marsilea L.) are heterosporous ferns and the most species rich group within the Marsileaceae. The family additionally comprises the pillworts (Pilularia L.) and the monotypic genus Regnellidium Lindm. All three genera are aquatic to semi- aquatic rhizomatous plants with roots and leaves born at nodes and sori arranged in sporocarps (Kramer, 1990; Nagalingum et al., 2006). Recent phylogenetic studies have revealed that the Clover ferns (Marsileaceae) together with the Floating ferns (Salviniaceae; Salvinia Seg. and Azolla Lam.) represent a monophyletic group of heterosporous ferns within the fern clade, which evolved in the Mesozoic (Pryer, 1999; Smith et al., 2006; Nagalingum et al., 2006). Twentieth century treatments of the genus mainly focussing on morphology have been published for Africa (Launert, 1968, 1970, 1971, 1984), Australia (Jones, 1998), India (Gupta, 1962), and the Americas (Johnson, 1986).

There doesn't appear to be much recorded about the sporing times of our ferns. At a recent Fern Seminar in Armidale, John Williams of New England University deplored the lack of this basic information for anyone interested in propagating ferns. Our Leader raised the subject at the February meeting at Stony Range and suggested ways in which we could approach the project. Important considerations mentioned by Peter included the need to gather many individual recordings, the location and effect of climate, and whether the ferns are growing in the wild or in cultivation, and if in ,;; cultivation, whether g ow? in pots or in the ground. We don't know what effect these varigag Rage on sporing times, or even if ferns of the one species of the same age and grown in similar conditions, always spore at a particular time of the year. Peter said he suspected that rainfall could be a factor which caused certain ferns to set spores — but we do not know.

The Vegetation of the Western Australian Deserts
©Reinhold-Tüxen-Gesellschaft (http://www.reinhold-tuexen-gesellschaft.de/) Ber. d. Reinh.-Tüxen-Ges. 18, 219-228. Hannover 2006 The Vegetation of the Western Australian Deserts - Erika and Sandro Pignatti, Rom - Abstract The internal area of W. Australia has arid climate and conditions for plant growth are particularly difficult. The surface of this huge, almost uninhabited territory consists of four landscape systems: the Great Sandy Desert, the Little Sandy Desert, the Great Victoria Desert, the Gibson Desert. The four deserts extend between 21-26° of south- ern latitude, linking to the central Australian deserts and the Nullarbor Plain in the South. Meteorological stations are only in settlements of the surrounding semi-desert areas (Wiluna, Meekatharra, Cue, Warburton), and all show around 200-250 mm year- ly rainfall; in the centre of the deserts rainfall is still much lower, and indicated as “erratic and unreliable”; some areas may lack rain for several years. Despite of the par- ticularly severe ecological conditions, most of the surface is covered by vegetation (at least a discontinuous one) and during expeditions in 2001 and 2002 over 700 species were collected and more than 350 phytosociological relevés were carried out.Two main habitat types can be recognized: Mulga – scattered growth of treelets (Acacia aneura, generally about 3-4 m height), with open understorey (Senna, Eremophila, Solanum) and herbs usually covering less than 20 % of the surface; in the Gibson Desert mulga occurs mainly on hard rock sub- strate (granite, laterite). Because of the discontinuous plant cover, fire can spread only over limited areas. Spinifex – Quite a compact cover of perennial grasses (several species of Triodia, with sharply pointed leaves in dense tussocks 3-5 dm high, panicles up to 1 m and high- er) in monospecific populations covering 60-80 % of the surface; in the sandy deserts, on siliceous sand.

Marsilea: Habit and Habitat of Marsilea: Marsilea is commonly known as “pepper wort” or “water fern” (although it is a fern but hardly resembles a true fern). It is represented by about 53 species which are cosmopolitan in distribution but abundantly found in tropical countries like Africa and Australia. About 9 species have been reported from India. Either the species are hydrophytic or amphibious i.e., they grow rooted in mud or marshes and shallow pools or are completely submerged or partially or entirely out of water in wet habitats. M. hirsuta is an Australian xerophytic species. M. hirsuta and M. quadrifolia are two most common Indian species usually found growing in marshy places, wet soil or near muddy margins of ponds and are commonly found in U.P., Punjab, Bihar, Delhi etc. External Features of Marsilea: The mature sporophyte is an herbaceous plant. Its underground rhizome spreads in a diameter of 25 meter or more. The plant body is distinctly differentiated into rhizome, leaves and roots (Fig. 1 A). 1. Rhizome: All the species possess a rhizome which creeps on or just beneath the soil surface. It is slender, dichotomously branched with distinct nodes and internodes and is capable of indefinite growth in all directions as a result of which it occupies an area of 25 metre or more in diameter. In aquatic species the internodes are long while in sub-terrestrial species they are short. Usually from the upper side at nodes, the leaves are given out while from their lower side, the roots. 2. Leaves: They are borne alternately on upper side of rhizome at nodes, in two rows.

Structure and Function of Spores in the Aquatic Heterosporous Fern Family Marsileaceae
Int. J. Plant Sci. 163(4):485–505. 2002. ᭧ 2002 by The University of Chicago. All rights reserved. 1058-5893/2002/16304-0001$15.00 STRUCTURE AND FUNCTION OF SPORES IN THE AQUATIC HETEROSPOROUS FERN FAMILY MARSILEACEAE Harald Schneider1 and Kathleen M. Pryer2 Department of Botany, Field Museum of Natural History, 1400 South Lake Shore Drive, Chicago, Illinois 60605-2496, U.S.A. Spores of the aquatic heterosporous fern family Marsileaceae differ markedly from spores of Salviniaceae, the only other family of heterosporous ferns and sister group to Marsileaceae, and from spores of all ho- mosporous ferns. The marsileaceous outer spore wall (perine) is modified above the aperture into a structure, the acrolamella, and the perine and acrolamella are further modified into a remarkable gelatinous layer that envelops the spore. Observations with light and scanning electron microscopy indicate that the three living marsileaceous fern genera (Marsilea, Pilularia, and Regnellidium) each have distinctive spores, particularly with regard to the perine and acrolamella. Several spore characters support a division of Marsilea into two groups. Spore character evolution is discussed in the context of developmental and possible functional aspects. The gelatinous perine layer acts as a flexible, floating organ that envelops the spores only for a short time and appears to be an adaptation of marsileaceous ferns to amphibious habitats. The gelatinous nature of the perine layer is likely the result of acidic polysaccharide components in the spore wall that have hydrogel (swelling and shrinking) properties. Megaspores floating at the water/air interface form a concave meniscus, at the center of which is the gelatinous acrolamella that encloses a “sperm lake.” This meniscus creates a vortex-like effect that serves as a trap for free-swimming sperm cells, propelling them into the sperm lake.
