A.M., R.H.S. 1916; AA clxi.;
Dykes, The Genus Iris 1913Description. Rootstock , a compact somewhat slender rhizome. Leaves , pale yellow-green, about 18 in. by 1½ in., without the conspicuous midrib of I. Kaempferi Stem , stout, somewhat crooked, bearing one reduced leaf below the middle and a terminal head of 3-4 flowers. There are also 2 small leaves at the base. In very strong specimens a lateral head of 2-3 flowers may develop. Spathe valves , green, navicular, unequal, sharply keeled, reaching above the tube; the inner valve is sometimes as much as 4 in. in length, while the outer is only 2½ in. Pedicel , short at first, and not much above an inch in the fruiting state. Ovary , rounded trigonal with a slightly raised ridge down the centre of each side. Tube , ½-1 in. Falls . The large ( 2½ by 2 in.) obovate blade is about twice as long as the small narrow canaliculated haft. The latter is yellow, edged with purplish blue, and the central yellow ridge extends on to, and expands a little on, the blade. The colour is a rich deep blue. Standards , erect, oblanceolate, about 2½ in. long. Styles , 1 - 1 ½ in. long, becoming wider upwards. Crests , large and rounded. Stigma , obscurely bilobed. Filaments , short, white. Anthers , twice as long as the filaments, white, the pollen sacs being narrow and separated by a distinct interval. Potten , creamy white. Capsule , 2 in. long, oblong, much-rounded trigonal, with blunt ends (see Fig. 8). Seeds , semi-circular, compressed, encased in thick, loose, smooth, glossy, pale brown coats. The effect of this loose coat is that the seeds float in water.Observations.The differences between this species and/. Kaempferi will be found described in the Observations on the latter. The typical plant is still very rare in cultivation, at any rate in Europe, although garden forms from Japan have been known for some years under the name of I. albopurpurea. This came originally to Kew by chance, mixed up with plants of I. Kaempferi and was described by Baker as a species. A few years ago I obtained from Japan a plant or two of the blue-flowered type under the name of I. albopurpurea and, when these flowered, it was at once obvious that this was the plant of which albopurpurea is a quasi-albino garden form. The latter breeds true from seed as regards colour, for all the seedlings of the original Kew plants that have so far flowered with me have borne white flowers mottled and spotted with blue purple (see Plate XVIII). From this plate the type may be pictured by imagining the deep blue colour to obscure the white throughout. It was intended to have a plate of the typical plant, but unfortunately my two plants were both flowerless, having been allowed to seed freely in the previous year, and a specimen of atbopurpurea had therefore reluctantly to be substituted. In all botanical details the variety is identical with the type, and it is only the colour that is different.Little evidence is available as to doubling in Iris flowers, but it may be worth while to record here that among seedlings raised from the original Kew plants of atbopurpurea several double-flowered plants have appeared, similar in every way to the ugly monstrosities that are often sent from Japan under the name of I. albopurpurea.The cultivation of this species presents no special difficulty provided that the soil is fairly rich in humus, not charged with lime nor allowed to become too dry in summer.By the kindness of Dr B. Fedtschenko I have recently been allowed to see the unique specimen on which Maximowicz founded his I. Maacki. This was found by Maack on the left bank of the Ussuri opposite the mouth of the Ima, and consists merely of a few leaves and the upper part of a branched stem bearing mature capsules of ripe seeds. The oblong capsules vary in size, but the largest is nearly 3½ in. long, and all have the characteristic short broad beak of the species. The seeds too are dark brown, with smooth skins (cf. Plate XLVIII, fig. 1). Mme Olga Fedtschenko has recently sent me a copy of a note printed in Kneucker's Allgemeine Botanische Zeitschrift no. 6, 1906, in which she also comes to the conclusion that I. Maacki is nothing but a synonym of I. laevigata. The plant was originally identified by Regel as I. pseudacorus (Tent. Fl. U ssur. 490 ), which does not, however, extend into Eastern Asia.
