■ (SPEC) Iris x fulvala Dykes

1913, Dykes

Iris x fulvala (William Rikatson Dykes, 1913) In The Genus Iris: 81 (1913). Dykes notes "Evidence of the affinity of I. fulva and I. foliosa is found in the fact that the former proved to be readily fertile to pollen of the latter. Moreover the hybrid, I. fulvala, has proved not only to be entirely sterile, as is usually the case with hybrids between two widely separated species of Iris. On the other hand, we may take it that the two species are distinct, since the hybrid does not show "dominance" in any character, but is distinctly a compromise between the features of the two parents. Thus the foliage neither dies away entirely in autumn like that of I. foliosa, nor remains green and of considerable length like that of I. fulva. For the young growths push up soon after the flowers are over and are 4 or 6 inches long in winter, while those of I. foliosa are still only 1 in. long, and those of I. fulva a foot at least. The stem is more like that of I. fulva than like that of the pollen parent, but is sturdier. The flowers are the shape of I. foliosa, with perhaps more rounded segments, and the colour is distinctly a compromise between the terra cotta of I. fulva and the blue-purple of I. foliosa. The figure of a flower of I. fulvala shows the form in which the influence of the colour of I. fulva is most apparent. I have also from the same pod of seed other plants in which the shade of colour has distinctly more of the blue-purple of I. foliosa in it." See below:
