Loss of habitat due to residential and agricultural development (particularly Geographic Coverage: Rangewide for citrus groves), as well as fire suppression in tracts of remaining habitat, are the principle threats to this plant. This account represents a revision of the existing Figure 1. County distribution of scrub mint. recovery plan for the scrub mint (FWS 1987). Description The scrub mint is a dense or straggly, low-growing shrub (Kral, 1983). It reaches 50 cm in height and grows from a deep, stout, spreading-branching taproot. Its branches are mostly spreading, and sometimes are prostrate. Its shoots have two forms, one which is strictly leafy and overwintering, and another which is flowering and dies back after fruiting. The leaves vary in shape. They can be narrowly oblong- elliptic, linear-elliptic, or linear-oblanceolate (Kral 1983). The upper surface of the leaves is dark green, with the midrib slightly impressed. The lower surface is slightly paler, with the midrib slightly raised. They are 1.5 to 2.5 cm long, 2 to 3 mm wide, subsessile, flattish but somewhat fleshy, narrowly or broadly rounded at the apical end, have entire margins, and are not revolute.

  • 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.

  • Invasive Alien Plants an Ecological Appraisal for the Indian Subcontinent
    Invasive Alien Plants An Ecological Appraisal for the Indian Subcontinent EDITED BY I.R. BHATT, J.S. SINGH, S.P. SINGH, R.S. TRIPATHI AND R.K. KOHL! 019eas Invasive Alien Plants An Ecological Appraisal for the Indian Subcontinent FSC ...wesc.org MIX Paper from responsible sources `FSC C013604 CABI INVASIVE SPECIES SERIES Invasive species are plants, animals or microorganisms not native to an ecosystem, whose introduction has threatened biodiversity, food security, health or economic development. Many ecosystems are affected by invasive species and they pose one of the biggest threats to biodiversity worldwide. Globalization through increased trade, transport, travel and tour- ism will inevitably increase the intentional or accidental introduction of organisms to new environments, and it is widely predicted that climate change will further increase the threat posed by invasive species. To help control and mitigate the effects of invasive species, scien- tists need access to information that not only provides an overview of and background to the field, but also keeps them up to date with the latest research findings. This series addresses all topics relating to invasive species, including biosecurity surveil- lance, mapping and modelling, economics of invasive species and species interactions in plant invasions. Aimed at researchers, upper-level students and policy makers, titles in the series provide international coverage of topics related to invasive species, including both a synthesis of facts and discussions of future research perspectives and possible solutions.

  • Staminal Evolution in the Genus Salvia (Lamiaceae): Molecular Phylogenetic Evidence for Multiple Origins of the Staminal Lever
    Staminal Evolution In The Genus Salvia (Lamiaceae): Molecular Phylogenetic Evidence For Multiple Origins Of The Staminal Lever Jay B. Walker & Kenneth J. Sytsma (Dept. of Botany, University of Wisconsin, Madison) Annals of Botany (in press) Abstract • Background and Aims - The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective. The recent demonstration of the non-monophyly of the genus presents interesting implications for staminal evolution in the tribe Mentheae. In the context of a molecular phylogeny, we characterize the staminal morphology of the various lineages of Salvia and related genera and present an evolutionary interpretation of staminal variation within the tribe Mentheae. • Methods. Two molecular analyses are presented in order to investigate phylogenetic relationships in the tribe Mentheae and the genus Salvia. The first presents a tribal survey of the Mentheae and the second concentrates on Salvia and related genera. Schematic sketches are presented for the staminal morphology of each major lineage of Salvia and related genera. • Key Results. These analyses suggest an independent origin of the staminal elongate connective on at least three different occasions within the tribe Mentheae, each time with a distinct morphology. Each independent origin of the lever mechanism shows a similar progression of staminal change from slight elongation of the connective tissue separating two fertile thecae to abortion of the posterior thecae and fusion of adjacent posterior thecae. We characterize a monophyletic lineage within the Mentheae consisting of the genera Lepechinia, Melissa, Salvia, Dorystaechas, Meriandra, Zhumeria, Perovskia, and Rosmarinus. • Conclusions.

Unlike dill, herbs through horseradish, or rosemary, savory is not one distinct species. It is a general term that covers mainly the educational genus Satureja, but as time and botanists have fractured the many plants that have been called programs, savories, the title now refers to multiple genera.

(LAMIACEAE) FROM KASHMIR HIMALAYA REYAZ AHMAD MALIK*, RAGHBIR CHAND GUPTA, AND SANTOSH KUMARI Department of Botany, Punjabi University, Patiala, Punjab, India 147002 Received October 13, 2011; revision accepted February 17, 2012 Our cytomorphological study of various populations of Elsholtzia ciliata (Lamiaceae) collected from high-alti- tude sites of Kashmir Himalaya revealed two euploid cytomorphotypes, diploid (n=8) and tetraploid (n=16), growing sympatrically but inhabiting two different habitats. This is the first report of tetraploid (4×) E. ciliata from the Indian subcontinent. We found the course of meiois to be normal in diploids, but tetraploid individu- als showed chromosome and meiotic irregularities: cytomixis at early prophase I, stickiness at metaphase I, and chromosome bridges at anaphase I. In tetraploids, 23 of the 26 pollen mother cells observed at metaphase I showed 0–6 quadrivalents, suggesting that the tetraploid is a segmental allopolyploid. Microsporogenesis was also abnormal in tetraploids, showing the formation of triads. All these anomalies are conducive to lower repro- ductive potential (40.70%) in tetraploids than in diploids (90.50%). Significant morphological differences between the two cytotypes are presented.
