Lamiaceae is an important plant family that inhabits various ecosystems and has great diversity, is considered a cosmopolitan plant and has an important role in pharmaceutical and cosmetic sciences ...because of its essential oil content in almost every species. This research was focused on identify plant species from the Lamiacecae family that potential as essential oil producer in West Sumatra with their distribution based on ANDA Herbarium specimens. Data was collected use the herbarium method and literature study to determine the potential of each species. The results showed in the ANDA Herbarium were 45 species from 20 genera, which dominated by species that have the potential to produce essential oils as many as 23 species, followed by species that had not explore for their essential oil content as 11 species and commercial species, 9 species. Species from most Lamiaceae family were potentially as essential oil producer found in Padang city administrative area. Keywords: Cosmopolitan, genera, commercial, distribution, potential
Morphology and DNA sequences are used to describe a new species of New Guinea Worm-Eating Snake (Elapidae: Toxicocalamus Boulenger, 1896) from Papua New Guinea: Toxicocalamus goodenoughensis n. sp., ...endemic to Goodenough Island of the D’Entrecasteaux Archipelago. Toxicocalamus goodenoughensis morphologically most closely resembles T. pachysomus Kraus, 2009, but it differs by having undivided nasal scales completely surrounding nares (vs. divided), pale yellow markings on supralabials (vs. purple), a yellow nape band (vs. unbanded uniform nape), a dark gray-brown dorsum (vs. medium brown), dark brown mottling on yellow ventral scales, darkening toward cloaca (vs. uniform light brown), and >175 ventral scales. Phylogenetically, T. goodenoughensis is sister to another D’Entrecasteaux endemic, T. nigrescens Kraus, 2017. Coalescent-based species delimitation found the new species to be uniquely delimited from all other taxa (n = 13) in all combinations of parameters settings. Micro-computed tomography (μCT) scanning revealed the presence of distinctive variation in postfrontal bone morphologies, with three morphotypes exhibited within the genus: directed forward, directed lateral/perpendicular to cranium, and absent. Toxicocalamus goodenoughensis was found to have a sickle-shaped and directed forward postfrontal bone. The directed forward morphotype was shared by T. loriae clade 3 (sensu Strickland et al., 2016), T. mintoni, T. nigrescens, and T. pachysomus. Our work is the most comprehensive phylogenetic analysis of the genus and the first study using μCT scanning for comparative morphology of Toxicocalamus. We also provide an updated dichotomous key for the genus.
Summary
An account of the discovery, taxonomy and cultivation of Gymnospermium darwasicum is provided. Along with a supplement of Gymnospermium illustrations and studies published since Stearn's ...Monograph (2002).
Summary
A history of over 400 years of cultivation and taxonomy of Leontice leontopetalum is provided. Statements that it is native to Italy still require confirmation.
ABSTRACT This paper presents the results obtained from the analysis of the zooarchaeological bird assemblages of the Pizzulic 2, Pizzulic 3 and Pizzulic 4 sites, located in the Englefield island, ...whose radiocarbon dates show occupations from the Middle Holocene to the first millennium of our era. The analysis of the avifauna made it possible to determine the existence of continuity in the exploitation and selection of birds for these three sites, exploiting a reduced taxonomic range and a selection focused mainly on the Phalacrocoracidae Family. Zooarchaeology, bird exploitation, middle and late Holocene, marine hunter-gatherers, taxonomic diversity. INTRODUCCIÓN Las estrategias de subsistencia en contextos de cazadores-recolectores marinos en los sitios del estrecho de Magallanes y seno Otway se observan, en general, dominadas por una especialización en la caza marina, principalmente de presas de mayor tamaño como pinnipedos (Emperaire & Laming, 1961; Legoupil, 1997; Legoupil et al. 2011; San Román, 2013; San Román et al. 2016), que presentan una mayor biomasa consumible y un elevado aporte de proteínas y grasas.
Taxonomy is as old as the human language; it arose from the need to differentiate and name edible as well as poisonous plants and to be able to pass on this knowledge to the next generation ...
