Plants of Senecio triangularis with narrow, subentire leaves that taper to the petioles are occasionally encountered in acid bogs in Oregon and Washington and less frequently elsewhere. They are regarded as edaphic variants; they have been recognized as var. angustifolius.

Senecio triangularis ( 英語 )

由wikipedia EN提供

Senecio triangularis, known as arrowleaf ragwort,[3] arrowleaf groundsel and arrowleaf butterweed, is a species of the genus Senecio and family Asteraceae.

Description

The green involucral bracts have black tips with hairy tufts.[4]

It is similar in form to Senecio serra, both being four feet tall, have narrow and serrated leaves, and are topped with many small, yellow sunflowers. but S. triangularis is more common than S. serra.[5] S. triangularis has single erect stems, reaching up to 10–120 cm (4–47 in) tall.[6] The stems have evenly distributed leaves.[2] The leaves are triangular, with tapered ends,[2][5] hence the name.

As some plants are diploid, meaning having two sets of chromosomes, this can be used to identify hybrids and classification of groupings. It has been counted as 2n = 40, 80.[2]

It is native to temperate regions of America[7] and is reportedly poisonous to animals.[8]

Taxonomy

It has the common names of arrowleaf ragwort, arrowleaf groundsel,[6] and arrowleaf butterweed.

In the early 1830s, Scottish botanist Thomas Drummond collected this plant, probably on his second trip to the United States. The plant was named by William Hooker, Drummond's mentor, and first published and described by Hooker in 'Flora Boreali-Americana' (Fl. Bor.-Amer.) Vol.1 on page 332 in 1834.[2][5]

Distribution

Native
Nearctic:
Subarctic America: Northwest Territory, Yukon Territory, Alaska
Western Canada: Alberta, British Columbia
Northwestern United States: Colorado, Idaho, Montana, Oregon, Washington, Wyoming
Southwestern United States: Arizona, California, Nevada, Utah, New Mexico

Source: GRIN,[7]

Habitat

It grows in open woodlands, (mainly coniferous forests) and on rocky stream sides.[2][5] They can grow at altitudes of between 100 and 3,500 m (330 and 11,480 ft).[2]

Senecio triangularis ( 荷蘭、佛萊明語 )

由wikipedia NL提供

Senecio triangularis is een kruiskruid dat van nature voorkomt in de westelijke helft van Noord-Amerika, van New Mexico tot Canada en Alaska[1]. In de Verenigde Staten wordt ze arrowleaf groundsel, Arrow-Leaf Ragwort en Flat Tops genoemd. Het arrowleaf, pijlpunt, en de soortaanduiding triangularis verwijzen naar de driehoekige vorm van de bladeren.[2] De plant werd voor het eerst voor wetenschappelijk doel verzameld door Thomas Drummond, en beschreven door William Hooker[3].

Beschrijving

De gele bloemhoofdjes zijn 7-10 mm hoog en bloeien van juni tot september. Ze bevatten zowel buisbloemen als straalbloemen en zijn omgeven door acht tot dertien omwindselblaadjes. De bloemhoofdjes staan gegroepeerd op gelijke hoogte aan de top van de plant. Elk bloemhoofdje kent vijf tot acht straalbloemen.

De 4-20 cm lange en 2-10 cm brede bladeren staan langs de 30-150 cm hoge stengel. De bladeren zijn gesteeld en grof getand. De bovenste bladeren zijn kleiner dan de onderste. De basis van de bladeren is vlak, waardoor het blad de vorm van een driehoek heeft. Dit is een van de belangrijkste verschillen met Senecio serra, die in dezelfde streken voorkomt, maar gewoonlijk op minder vochtige plaatsen[2][3][4]

Toepassingen

De plant bevat verschillende alkaloïden, vooral senecionine, en kleinere hoeveelheden integerrimine, platy-phylline, rosmarinine, retrorsine, triangularine en neotriangularine.[5]

Ecologie

De plant komt voor als onderdeel van het 'Alpine-Montane Wet Meadow system' in de Rocky Mountains. Deze komt voor op subalpiene en lagere berghellingen en vochtige weiden. De plant wordt gegeten door herten, rendieren en schapen[4].
