Rosa primula and Rosa xanthina

Two early blooming yellow species roses, Rosa primula and Rosa xanthina, are back in bloom after a few years recovering from being moved. The first picture is mostly Rosa primula (there's one branch of Rosa xanthina sneaking into the picture).  The second picture shows the two side by side for comparison - the darker yellow is Rosa xanthina. The third picture shows some blooms on white paper, as I was getting them ready to collect and store pollen for later in the season when other species bloom.
