Trun en Flor

Acaena argentea

Description:

Cadillo, trun, amores secos, zarzaparrilla, proquín, pega pega.
Family of Rosaceae.
Acaena is a genus of about one hundred species and sub-species of perennial herbs and subshrubs in the Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaiʻi (A. exigua) and California (A. pinnatifida).
The leaves are alternate, 4–15 centimetres (1.6–5.9 in) long, and pinnate or nearly so, with 7-21 leaflets. The flowers are produced in a tight globose [inflorescence] 1–2 centimetres (0.39–0.79 in) in diameter, with no petals. The fruit is also a dense ball of many seeds; in many (but not all) species the seeds bear a barbed arrowhead point, the seedhead forming a burr which attaches itself to animal fur or feathers for dispersal.

Acaena es un género de plantas perteneciente a la familia Rosaceae. Comprende 19 especies que se distribuyen por el hemisferio sur, principalmente en Nueva Zelanda, Australia y en Sudamérica, unas pocas especies se extienden al hemisferio norte, con A. pinnatifida en California y A. exigua en Hawaii.
Son hierbas perennes y subarbustos con hojas alternas de 4-15 cm de longitud, pinnadas o casi con 7-21 hojas. Las flores se pruducen en inflorescencias globosas de 1-2 cm de diámetro, sin pétalos. Los frutos son también densos globos con muchas semillas.

Habitat according to altitude:
Medium altitude up to the timber line
0 to 2000 m.a.s.l.

Humid areas, with almost constant rainfall. Short dry periods are possible (generally not longer than 1 month).

Notes:

You notice these stuck to your shoes, socks and clothes when you get home after a walk.
This spotting is rather special for me because despite this plant being a common weed I've never seen it in such notorious bloom.

Este spotting es especial porque a pesar de ser una males común, nunca había visto un trun en flor de esta manera tan notoria.
Estos se pegan en los zapatos, ropa y calcetines, siendo bien difíciles de sacar.
