Arenaria montana

Arenaria montana



Arenaria montana, the mountain sandwort,[1] is a species of flowering plant in the family Caryophyllaceae, native to mountainous regions of southwestern Europe, from the Pyrenees to Portugal.[2]

Description[edit]

Arenaria montana is an evergreen perennial growing 14–22 cm (6–9 in) tall, with lanceolate or ovate green to grayish-green opposite leaves 0.5 to 1 inches (1 to 3cm) in length.
From mid to late Spring it produces dense clumps of white to near-white flowers approximately 2.5 cm (1 in) in diameter borne on cymes of 2 to 10 flowers each.[3][4][2]
Arenaria montana prefers well drained, sandy to sandy loam soils, of moderate (pH 5.5 to 7.5) acidity. It also prefers moist soils, as its shallow root system leaves it vulnerable to drought.[2][4]

Arctotis

Arctotis



Arctotis is a genus of annual and perennial plants in the family Asteraceae.[4][2]
Arctotis is native to dry stony slopes in southern Africa. Some of the plants are alternatively placed in the genus Venidium. The common name is "African daisy", or "Gousblom" in Afrikaans. These plants have daisy-likecomposite flowers which tend to close in the late afternoon or in dull weather,[5] but numerous cultivars have been developed for garden use which stay open for longer, and are available in a wide range of colours. Tenderperennials are often grown in temperate regions as half-hardy annuals.
The garden hybrid A. × hybrida hort. 'Flame' has gained the Royal Horticultural Society's Award of Garden Merit.[6]

Aponogeton

Aponogeton


The Aponogetonaceae (Cape-pondweed family or Aponogeton family) are a family of flowering plants in the order Alismatales. The Aponogetonaceae is considered to be allied to the Potamogetonaceae - Najadaceaecomplex of families.
In recent decades the family has had universal recognition by taxonomists.[2] The APG system (1998) and APG II system (2003) treat it in the order Alismatales in the clade monocots. The family consists of only one genus,Aponogeton, with 40–50 species of aquatic plants, most of which have been included in a molecular phylogeny by Chen et al. (2015). The name was published in Supplementum Plantarum 32: 214 (1782) and is derived from a geographic location. Some species are used as ornamental plants in aquariums.

Anthemis cotula

Anthemis cotula



Anthemis cotula, also known as stinking chamomile,[6] is a flowering annual plant with a noticeable and strong odor. The odor is often considered unpleasant, and it is from this that it gains the common epithet "stinking". It is initially native to Europe and North Africa. It has successfully migrated to North America, Southern Africa, Australia and New Zealand[7] where it can be found growing on waste ground, alongside roads, and in fields.[8] Anthemis cotula is considered a weed due to its propensity for invading cultivated areas.[7]
The name "cotula" is from a Greek word for "small cup", describing the shape of the flowers; it was assigned by Carl Linnaeus in his work Species Plantarum in 1753.[9]
Anthemis cotula is also known by a wide variety of other names, including mather, dog- or hog's-fennel, dog-finkle, dog-daisy, pig-sty-daisy, chigger-weed,[8] mayweed, maroute, Maruta cotula, Cotula Maruta foetida, Manzanilla loca, wild chamomile, Camomille puante. Foetid Chamomile or Mayweed, maithes, maithen, mathor [10] mayweed chamomile, camomille des chiens, camomille puante, stinkende Hundskamille, camomila-de-cachorro, macéla-fétida, and manzanilla hedionda.
