Observed and photographed by Fabian Gonzalez. This appears to be an un-described species. Hairs on petals do not match those of Viola atropurpurea, which very rarely has yellow flowers. The plant seems more similar in the shape of the rosettes and hairs on petals to Viola skottsbergiana, a plant with white petals and similar markings on the lower petals.

Seems to match this observation found a short distance to the south on Nevado de Longaví.

In 10th photo, Nevado de Longaví, can be seen in the distance.

Growing at an altitude of 2980 m.
The population consists of thousands of plants that are all consistently yellow or yellow-orange colored.

Other yellow flowered species in the Section Sempervivum include V. auricolor, which has smaller, more loosely arranged rosettes, and larger flowers compared to the size of the rosettes. It grows far to the south of this location.

Viola coronifera has yellow flowers that are arranged at a different angle on the rosettes.

Parece que es una especie desconocida. Los pelos de los pétalos son diferentes de los de Viola atropurpurea. Es mas parecido en la forma de las rosetas y en los pelos de los pétalos a Viola skottsbergiana, que tiene pétalos blancos con manchas parecidas.

Parece bastante parecido a esa observación del Nevado de Longaví, que está unos 30 kilometros al sur:

Crece a una altura de 2980 msnm.

Otras violas de la sección Sempervivum con flores amarillas incluye Viola auricolor, que tiene rosetas mas pequeñas, con hojas no tan apretadas, y flores mas grandes en comparación al tamaño de las rosetas. Esa especie ocurre muy al sur.

Viola coronifera, que ocurre mas cerca al sur, tiene flores amarillas que salen en angulo diferente en las rosetas en comparación a esa especie.
