Ranunculus peduncularis

Description:

Botón de oro , Centella.
Ranunculus is a large genus of about 600 species of plants in the Ranunculaceae.
A few species have orange or red flowers. There are usually five petals, but sometimes six, numerous, or none. The petals are often highly lustrous, especially in yellow species.
The name Ranunculus is Late Latin for "little frog," from rana "frog" and a diminutive ending. This probably refers to many species being found near water, like frogs.
All Ranunculus species are poisonous when eaten fresh by cattle, horses, and other livestock, but their acrid taste and the blistering of the mouth caused by their poison means they are usually left uneaten. Poisoning can occur where buttercups are abundant in overgrazed fields where little other edible plant growth is left, and the animals eat them out of desperation. Symptoms include bloody diarrhea, excessive salivation, colic, and severe blistering of the mucous membranes and gastrointestinal tract. When Ranunculus plants are handled, naturally occurring ranunculin is broken down to form protoanemonin, which is known to cause contact dermatitis in humans and care should therefore be exercised in extensive handling of the plants. The toxins are degraded by drying, so hay containing dried buttercups is safe.

Ranunculus es un género de cerca de 600 especies de plantas de la familia Ranunculaceae.
Son sobre todo plantas herbáceas perennes con flores amarillas o blancas (o blanco con centro amarillo), algunas son anuales y otras bienales. Otras tienen flores rojas o anaranjadas o como la R. auricomus que no tiene pétalos.
Todas las especies son venenosas por su contenido en protoanemonina cuando son comidas por el ganado, pero su gusto acre hace que las desprecien. Al ser secadas el veneno se degrada.

Habitat:

From low to high altitude, above the tree line.
These where found at about 2700 m.a.s.l.

Elevación desde la costa hasta sobre el límite del bosque.
Estas fueron encontradas aproximadamente a unos 2.700 m.s.n.m.

Notes:

Puedo estar equivocado con la identificación, hay muchos ranúnculos en Chile, pero es la más probable según varias fuentes.
