Uses: It is used to suppress cough, dries secretions, reduces phlegm, to protects liver, kills viruses, reduces cholesterol, reduces blood pressure, supports gallbladder, as cardioprotective, increases urination, lowers blood sugar level, stimulates menstruation, used to treat respiratory tract diseases, for treatment of hair loss. It is used for the treatment of leprosy, animal bites, thyroid dysfunction and musculoskeletal disorders. Externally it is used for boils, eczema, and wounds. Side effects & Toxicity: Large doses may be emetic. Contraindications: A. capillus-veneris has been documented to lower blood sugar levels in animal studies. People with diabetes and people with hypoglycemia should use this plant with caution and monitor their blood sugar levels accordingly. A. capillus-veneris has a long history of use in herbal medicine systems to stimulate the uterus and promote menstruation; it is contraindicated in pregnancy. The plant has shown to have an anti-implantation effect in animal studies and may prevent conception. Couples seeking fertility treatment or pregnancy should not take A. capillus-veneris . Due to its effect on fertility and menstruation, A. capillus-veneris may have estrogen-like effects and should probably be avoided by women with estrogen-positive cancers. Drug Interactions: A. capillus-veneris may potentiate insulin and antidiabetic drugs. 27 Standard dosage: leaves or rhizomes, Infusion: 1/2 cup twice daily; Tincture: 1-3 ml twice daily; Capsules: 2 g twice daily.One-half cup leaf infusion twice daily or 1-3 ml of a 4:1 root tincture used twice daily. If desired, 1-2g of powdered leaf or root in tablets or capsules twice daily can be substituted. Pre-Clinical Studies: The plant has demonstrated little toxicity. However, in animal studies, it has been shown to have an antifertility effect. In the 1980s, two separate researchers in India found that a pet ether extract of the plant had an anti-implantation effect in rats, preventing conception. In 1989 scientists in Iraq demonstrated A. capillus-veneris 's antimicrobial properties. A methanol extract of the aerial parts was reported to have in vitro antimicrobial actions against Bacillus, E. coli, Staphylococcus, Proteus, Pseudomonas, and Candida. French scientists demonstrated that an ethanol extract of the rhizome evidenced antiviral properties in vitro against Vesicular stomatitis virus. Other early (1967) research showed that a water extract of the entire plant had hypoglycemic activity when given to mice (10 mg/kg) orally. Much later (in 1993), Belgium scientists confirmed that A. capillus-veneris leaves had in vivo hypoglycemic properties in mice. In one study, a water extract of the aerial parts was given to mice (25 mg/kg) orally and found to reduce glucose-induced hyperglycemia. An ethanol extract, however, showed no activity. They reconfirmed these findings in 1995 by demonstrating that a water extract reduced glucose- induced hyperglycemia. Physico-chemical parameters of Adiantum capillus-veneris L.

Roux Pretoria 2009 S T R E L I T Z I A This series has replaced Memoirs of the Botanical Survey of South Africa and Annals of the Kirstenbosch Botanic Gardens which SANBI inherited from its predecessor organisations. The plant genus Strelitzia occurs naturally in the eastern parts of southern Africa. It comprises three arborescent species, known as wild bananas, and two acaulescent species, known as crane flowers or bird-of-paradise flowers. The logo of the South African National Biodiversity Institute is based on the striking inflorescence of Strelitzia reginae, a native of the Eastern Cape and KwaZulu-Natal that has become a garden favourite worldwide. It sym- bolises the commitment of the Institute to champion the exploration, conservation, sustain- able use, appreciation and enjoyment of South Africa’s exceptionally rich biodiversity for all people.

    Morphological and Anatomical Adaptations to Dry, Shady Environments in Adiantum Reniforme Var

    Morphological and anatomical adaptations to dry, shady environments in Adiantum reniforme var. sinense (Pteridaceae) Di Wu1, Linbao Li1, Xiaobo Ma1, Guiyun Huang1 and Chaodong Yang2 1 Rare Plants Research Institute of Yangtze River, Three Gorges Corporation, Yichang, China 2 Engineering Research Center of Ecology and Agriculture Use of Wetland, Ministry of Education, Yangtze University, Jingzhou, China ABSTRACT The natural distribution of the rare perennial fern Adiantum reniforme var. sinense (Pteridaceae), which is endemic to shady cliff environments, is limited to small areas of Wanzhou County, Chongqing, China. In this study, we used brightfield and epifluorescence microscopy to investigate the anatomical structures and histochemical features that may allow this species to thrive in shady, dry cliff environments. The A. reniforme var. sinense sporophyte had a primary structure and a dictyostele. The plants of this species had an endodermis, sclerenchyma layers and hypodermal sterome, reflecting an adaption to dry cliff environments. Blades had a thin cuticle and isolateral mesophyll, suggesting a tolerance of shady environments. These characteristics are similar to many sciophyte ferns such as Lygodium japonicum and Pteris multifida. Thus, the morphological and anatomical characteristics of A. reniforme var. sinense identified in this study are consistent with adaptations to shady, dry cliff environments.

  • Fern Classification

    Fern Classification

    16 Fern classification ALAN R. SMITH, KATHLEEN M. PRYER, ERIC SCHUETTPELZ, PETRA KORALL, HARALD SCHNEIDER, AND PAUL G. WOLF 16.1 Introduction and historical summary / Over the past 70 years, many fern classifications, nearly all based on morphology, most explicitly or implicitly phylogenetic, have been proposed. The most complete and commonly used classifications, some intended primar• ily as herbarium (filing) schemes, are summarized in Table 16.1, and include: Christensen (1938), Copeland (1947), Holttum (1947, 1949), Nayar (1970), Bierhorst (1971), Crabbe et al. (1975), Pichi Sermolli (1977), Ching (1978), Tryon and Tryon (1982), Kramer (in Kubitzki, 1990), Hennipman (1996), and Stevenson and Loconte (1996). Other classifications or trees implying relationships, some with a regional focus, include Bower (1926), Ching (1940), Dickason (1946), Wagner (1969), Tagawa and Iwatsuki (1972), Holttum (1973), and Mickel (1974). Tryon (1952) and Pichi Sermolli (1973) reviewed and reproduced many of these and still earlier classifica• tions, and Pichi Sermolli (1970, 1981, 1982, 1986) also summarized information on family names of ferns. Smith (1996) provided a summary and discussion of recent classifications. With the advent of cladistic methods and molecular sequencing techniques, there has been an increased interest in classifications reflecting evolutionary relationships. Phylogenetic studies robustly support a basal dichotomy within vascular plants, separating the lycophytes (less than 1 % of extant vascular plants) from the euphyllophytes (Figure 16.l; Raubeson and Jansen, 1992, Kenrick and Crane, 1997; Pryer et al., 2001a, 2004a, 2004b; Qiu et al., 2006). Living euphyl• lophytes, in turn, comprise two major clades: spermatophytes (seed plants), which are in excess of 260 000 species (Thorne, 2002; Scotland and Wortley, Biology and Evolution of Ferns and Lycopliytes, ed.

Komarov Botanical Institute of RAS, Saint-Petersburg) and digital images of the herbarium specimens of M. graminea from the Herbaria P (Muséum National d’Histoire Naturelle, Paris) and BM (Natural History Museum, London) were analyzed. The collections contain six specimens collected by Ph. Commerson on Ile-de-France Island and representing the original material of Pteris graminea – the basionym of Monogramma graminea. The lectotype of Pteris graminea is designated here by I.I. Gureyeva, I.V. Sokolova, and A.V. Vaganov: “Ile de France. Herb. Commerson” (P: Р00674761). Four more specimens were identified as syntypes: P01344296; P01344312, left lower plant; P01420498 (all from P); BM000605316 (BM); LE00050576, upper plant (LE). The spores of the M.
