Convolvulus demissus

Description:

Correvuela andina
Perennial Creeping Plant of about 10cm high. It grows radiating from a central stem no more than 1 meter in diameter.
As most Convolvulus it tolerates moderate drought.
The colour ranges from white, to pink.
The growth pattern, the "crooked" leaves, smaller flower and tolerance for altitude is what distinguishes this species from the cosmopolitan Convolvulus arvensis.

Habitat:

It grows at medium to high altitude close to the timber line (1700 to 2700 meters above sea level) in the Andes Range, Chile and Argentina between about 30º to 36º South. These where found above 2500 meters above the sea level.
Watering conditions:
Somewhat dry areas where the drought may last 3 - 5 months.
Precipitations of 400 - 800 mm. concentrated in winter.
Light conditions:
Fully exposed to the sun. Level areas or slopes facing north.

Notes:

At first I thought them to be Convolvulus arvensis, and only by chance learned about this native version.
Next time will take more pictures.
