Antirrhinum (DRAFT)

Along Rd Eix Pirinenc N260, the same spot had all yellow flowers in 2013. By 2024, the area had few light magenta and a nearly white flower. The floral colors have changed significantly in just a few years, shifting from a uniform yellow to diverse shades.

(2024)

We are observing a stabilizing formation of the pseudomajus populations in the East.

The transitional phenomenon merged during the observing period (2018-2024) to the West or more uphill, with the tendency to get more magenta-red forms within their populations. On the contrary, within the adjacent yellow striatum populations, more and more white, orange, and magenta flowers were interspersed remarkably in east-oriented and wind-protected step slopes higher up (magenta dots in map).
The purpose of this summary is to highlight a clear trend we observed-the increasing prosperity of magenta pseudomajus populations more and more uphill. 

With a handheld spectrophotometer, we measured 42 upper lobes of 42 Antirrhinum striatum/pseudomajus flowers selected at random around the transition area of the taxa. The resulting L*a*b shows the pure forms at either end. The flesh indicates the trend of transition we postulate.
