  • Origin and Age of Australian Chenopodiaceae

Using a previously published rbcL phylogeny of the Amaranthaceae–Chenopodiaceae alliance (Kadereit et al. 2003) and new ITS phylogenies of the Camphorosmeae and Salicornieae, we conclude that Australia has been reached in at least nine independent colonization events: four in the Chenopodioideae, two in the Salicornieae, and one each in the Camphorosmeae, Suaedeae, and Salsoleae. Where feasible, we used molecular clock estimates to date the ages of the respective lineages. The two oldest lineages both belong to the Chenopodioideae (Scleroblitum and Chenopodium sect. Orthosporum/Dysphania) and date to 42.2–26.0 and 16.1–9.9 Mya, respectively. Most lineages (Australian Camphorosmeae, the Halosarcia lineage in the Salicornieae, Sarcocornia, Chenopodium subg. Chenopodium/Rhagodia, and Atriplex) arrived in Australia during the late Miocene to Pliocene when aridification and increasing salinity changed the landscape of many parts of the continent. The Australian Camphorosmeae and Salicornieae diversified rapidly after their arrival. The molecular-clock results clearly reject the hypothesis of an autochthonous stock of Chenopodiaceae dating back to Gondwanan times.

  • Sarcocornia Obclavata (Amaranthaceae) a New Species from Turkey
    Phytotaxa 49: 55–60 (2012) ISSN 1179-3155 (print edition) www.mapress.com/phytotaxa/ PHYTOTAXA Copyright © 2012 Magnolia Press Article ISSN 1179-3163 (online edition) Sarcocornia obclavata (Amaranthaceae) a new species from Turkey AHMET EMRE YAPRAK Ankara University, Faculty of Science, Department of Biology, 06100 Ankara, Turkey. E-mail: [email protected] Abstract Sarcocornia obclavata is described as a new species from Mediterranean Turkey. The main morphological characters that separate S. obclavata from other Sarcocornia species are the obclavate shape of its fertile segments, which is more obvious at lower fertile segments. Sarcocornia obclavata differs from S. perennis in having cymes on fertile segments that clearly do not reach the upper edge. It differs from S. fruticosa in having curved hairs on the seed testa. Key words: Mediterranean, Chenopodiaceae Introduction Sarcocornia Scott (1977: 366) is a genus of halophytic perennials with a nearly worldwide distribution, compromising ca 20–25 species (Steffen et al. 2010). Sarcocornia is distinguished from the annual Salicornia Linnaeus (1753: 3) in being shrubby perennials and by having flowers of equal height in the cymes (Scott 1977). Sarcocornia and Salicornia differ from Arthrocnemum Moquin-Tandon (1840: 111) in having membranous seeds that lack endosperm, and in their florets not being hidden behind bracts (Scott 1977). Molecular phylogenetic studies support the morphological distinctions between the three genera (Kadereit et al. 2006, Kadereit et al. 2007). The generic status of Sarcocornia is accepted in many recent taxonomical studies (Alonso & Crespo 2008, Steffen et al. 2009, Steffen et al. 2010). There are two Sarcocornia species known from the Mediterranean region (Piirainen 2009): S.

Sarcocornia neei, a halophytic plant growing in Chilean coastal areas, is highly tolerant to contaminated soils associ- ated with mine tailings. The potential for bioabsorption of heavy metals and arsenic and the substrate stabilization by this species was evaluated in soil experimentally contaminated with mine tailings from the Copiapó Valley. Sarcocornia neei grew well, although more slowly, in experimental soils containing mainly Fe, Cu and Mn. In an advanced vegetative development stage, S. neei roots were able to stabilize the contaminated experimental soils, agglomerating them in more than 80 % and extract- ing chemical elements from them. These characteristics are potentially useful for phytoremediation and reduction of contamination by fine-size particles from mine tailings and contaminated soils.

  • Avicennia Germinans (Acanthaceae) Gaining New Ground in Southeast Texas?
    Rosen, D.J. and S. Zamirpour. 2014. Avicennia germinans (Acanthaceae) gaining ground in southeast Texas? Phytoneuron 2014-74: 1–4. Published 22 July 2014. ISSN 2153 733X AVICENNIA GERMINANS (ACANTHACEAE) GAINING NEW GROUND IN SOUTHEAST TEXAS? DAVID J. ROSEN and SIAVASH ZAMIRPOUR Lee College Department of Biology P.O. Box 818 Baytown, Texas 77522 [email protected] ABSTRACT Avicennia germinans is documented for the first time from Brazoria County in southeast Texas. It perhaps indicates an expanding range for the species in Texas. Avicennia germinans (L.) L. (black mangrove) is a tropical and subtropical maritime shrub to small tree distributed along tidal shores from Texas to Florida, Bermuda, the Bahama Islands, both coasts of Mexico and Central America, the West Indies, and the coasts of Brazil, Peru, and West Africa (Correll & Johnston 1970; Godfrey & Wooten 1981). The northern distributional limit of Avicennia germinans has been suggested to be determined by the frequency and duration of freezing temperatures (Sherrod & McMillan 1981). In the Gulf of Mexico, A. germinans sees its northernmost limit in Texas. Herbarium records occur from the South Texas coastal counties of Aransas, Calhoun, Cameron, Kleberg, Nueces, and San Patricio (Fig. 1) with well established stands at three sites (Sherrod & McMillan 1981). The species does not occur northward again until Galveston and Jefferson (the northernmost limit) counties in southeast Texas (Fig. 1). Although probably a waif in Jefferson County, as reported by Sherrod and McMillan (1981), Guo et al. (2009), and suggested by few herbarium collections, a well established population occurs in tidal marsh adjacent to "The Lagoon" on northeast Galveston Island (Rosen, personal observation).
