*'Acutikor'* ([[Main.Bio.HybridizerDykesWR][William Rickatson Dykes]], 1910). Regeliocyclus. height 9-12" (11.5-15 cm) Falls conspicuously veined with deep brownish-purple on a creamy white ground, obvious signal, beard black-purple, standards darker. [[Spec.SpecAcutiloba][<em>Iris acutiloba </em>C. A. Meyer]] X [[Spec.SpecKorolkowii][<em>Iris korolkowii </em>Regel]].

In 1910 Dykes notes; I. ACUTILOBA X I. KOROLKOWII <br />"The result of this cross is a group of particularly pleasing plants. The seeds ripened in 1907 and germinated freely for an Oncocyclus in 1909. The young plants came well through last winter quite unprotected, and several have recently flowered. In habit the plants resemble small specimens of I. Korolkowii, the brown-purple colouration at the base of the leaves being present in some cases. The stem, about 12 in. high, bears a two-flowered spathe, and the flowers retain the characteristic shape of I. acutiloba, with connivent standards and almost horizontal falls. All the segments are pointed, as in acutiloba, and boldly veined with a warm shade of chocolate-brown on a white ground.<br />It is noteworthy that in this case the influence of the pollen-parent has been strong enough to produce a two-flowered, instead of a one-flowered, spathe, and the theory that the Oncocyclus and the Regelia groups of Irises are closely related would seem to be supported by the fact that hybrids between their members appear to be fertile". W. R. Dykes, Charterhouse, Godalming-

Dykes in 1921 wrote; NOTES ON IRISES. IRIS ACUTIKOR. (IRIS ACUTILOBA AND I. KOROLKOWI.) <br />It is a good many years ago now since, through the kindness of the authorities of the Tiflis Botanic Garden, I received some rhizomes of the Caucasian Oncocyclus species, Iris acutiloba. In the following year some of the plants flowered and, knowing that I should probably not succeed in keeping them alive, I fertilised them with pollen of I. Korolkowi. I obtained some seeds, which germinated with the usual irregularity and uncertainty of these hybrids. The plants, thus obtained, showed clearly the influence of their parents, and some at least of them, those that have survived, are both sturdier and more floriferous than either of the species from which they are derived.<br />The foliage is narrow, stiff and upright, except for the outer leaves in each tuft, which are inclined to be falcate. The stems overtop the leaves and are about nine inches or a foot in height, and bear either one or two flowers. The long, narrow spathes are entirely herbaceous, green in the lower part and slightly flushed with purple near the top.<br />The flowers have the poise of I. acutiloba, with the pointed outstretched outer segments or fails of that species. In the plant illustrated (Fig. 2), the falls are conspicuously veined with deep brownish purple on a creamy white ground. The dark signal patch of the Oncocyclus species is very obvious, and is formed by the coalescence of the veins. On the style branches the purplish veining almost wholly obscures the lighter ground, while the broad, pointed beard is composed of scattered dark, black-purple hairs. On the standards the colour scheme is the same as on the falls except that slight purplish shading partially obscures the cream-coloured ground between the veins, with the result that the standards look distinctly darker than the falls.<br />There is something peculiarly pleasing about the neat, clear-cut flowers with their conspicuous veining, and they always seem to attract attention when they are growing among the rest of my Regelia Irises. They are easy to cultivate, provided that the rhizomes are lifted in July and stored in dry quarters until October, when they should be replanted in well-drained, rich soil.<br />In another hybrid from the same cross, the veining is of a blue-purple colour, and both the standards and falls are rounder at the apex, as they are in some forms of I. Korolkowi. The falls tend to reflex instead of extending horizontally, and the signal patch is much broader, while the broad standards are held erect and do not curve in to meet one another". W. R. Dykes.
