  • Crassula Connata (Ruiz & Pav.) A
    Crassula connata (Ruiz & Pav.) A. Berger et al. in Engl. & Prantl erect pygmy-weed Crassulaceae - stonecrop family status: State Threatened, BLM strategic rank: G5 / S1S2 General Description: A dapted from Douglas et al. (1998-2002): A reddish annual herb that roots nodally. Stems hairless, ascending or erect, freely branching, 2-6 cm tall. Leaves opposite, pairs fused around the stem, entire, succulent, oblong to egg-shaped, 1.5-6 mm long. Floral Characteristics: Flowers axillary, generally 2 per leaf pair, usually 4-parted, greenish, and sessile or short-stalked, but stalk lengthening in fruit. Sepals 4, fused at the base, lanceolate with an acute to acuminate tip. Petals whitish, less than 2 mm, not longer than the sepals. Stamens 4 . Fruits: Follicles less than 2 mm long, purplish, ovoid, ascending, and 1-2 seeded. Identifiable A pril to May. Identif ication Tips: This species is not in Hitchcock & Cronquist (1 9 7 3 ). Cras s ula tillaea is a nonnative weedy species that can also be found on coastal bluffs in WA , but it generally has 3 sepals, while C. connata generally has 4 sepals. C. aquatica is a native species that occurs in wetter habitats (mud flats, salt marshes); it has 1 flower per leaf pair, 6-17 seeds per follicle, and 4 rounded to obtuse sepals that are shorter than the petals. In contrast, C. connata usually has 2 flowers per leaf pair, 1-2 seeded fruits, and acute sepals that are longer than or equal to the petals. Sedum species are related, but are perennials, usually with 5-parted flowers and 10 stamens.

  • H3.3 Macaronesian Inland Cliff
    European Red List of Habitats - Screes Habitat Group H3.3 Macaronesian inland cliff Summary The perennial vegetation of crevices and ledges of cliff faces in Macaronesia away from coastal salt-spray is of very diverse character - some, for example, dominated by succulents, others rich in ferns and bryophytes characteristic of shaded situations - and it includes several hundreds of taxa endemic to the archipelagoes. The main threats are mountaineering and rock climbing, outdoor sports and leisure activities, and construction of infrastructures such as roads and motorways. Synthesis There is no evidence of significant past reductions, either in the last 50 years or historically, and also future prospects are good, as no serious threats are envisaged, besides touristic/leisure activities and putative faulty environmental impact assessments that may overlook this habitat as valuable. Reduction in quantity, reduction in quality and criteria of geographic distribution yield the Least Concern (LC) category. In spite of the LC category, conservation policy and management should restrict to the maximum any threat to or reduction of the habitat, as it has a very high conservation value, because of high endemism of species and communities with many local and regional variaties. Overall Category & Criteria EU 28 EU 28+ Red List Category Red List Criteria Red List Category Red List Criteria Least Concern - Least Concern - Sub-habitat types that may require further examination Four general subtypes can be distinguished based on species composition and different ecological conditions. However, at present, no data are available to carry out an individual assessment of each of them. In the future, if detailed plot sampling has been carried out, such an evaluation may be possible.

  • A Numerical Taxonomy of the Genus Rosularia (Dc.) Stapf from Pakistan and Kashmir
    Pak. J. Bot., 44(1): 349-354, 2012. A NUMERICAL TAXONOMY OF THE GENUS ROSULARIA (DC.) STAPF FROM PAKISTAN AND KASHMIR GHULAM RASOOL SARWAR* AND MUHAMMAD QAISER Centre for Plant Conservation, University of Karachi, Karachi-75270, Pakistan Federal Urdu University of Arts, Science and Technology, Gulshan-e-Iqbal, Karachi, Pakistan Abstract Numerical analysis of the taxa belonging to the genus Rosularia (DC.) Stapf was carried out to find out their phenetic relationship. Data from different disciplines viz. general, pollen and seed morphology, chemistry and distribution pattern were used. As a result of cluster analysis two distinct groups are formed. Out of which one group consists of R. sedoides (Decne.) H. Ohba and R. alpestris A. Boriss. while other group comprises R. adenotricha (Wall. ex Edgew.) Jansson ssp. adenotricha , R. adenotricha ssp. chitralica, G.R. Sarwar, R. rosulata (Edgew.) H. Ohba and R. viguieri (Raym.-Hamet ex Frod.) G.R. Sarwar. Distribution maps of all the taxa, along with key to the taxa are also presented. Introduction studied the genus Rosularia and indicated that the genus is polyphyletic. Mayuzumi & Ohba (2004) analyzed the Rosularia is a small genus composed of 28 species, relationships within the genus Rosularia. According to distributed in arid or semiarid regions ranging from N. different workers Rosularia is polyphyletic. Africa to C. Asia through E. Mediterranean (Mabberley, There are no reports on numerical studies of 2008). Some of the taxa of Rosularia are in general Crassulaceae except the genus Sedum from Pakistan cultivation and several have great appeal due to their (Sarwar & Qaiser, 2011). The primary aim of this study is extraordinarily regular rosettes on the leaf colouring in to analyze diagnostic value of morphological characters in various seasons.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese
