| Foster in The Garden, February 18, 1893 offers the following; "This is so well known that I need say little about it. Its distinguishing features may be briefly summed up thus: The root is compact, the leaves are relatively large, sometimes a foot or even more in height, and nearly an inch in breadth, distinctly yellowish green. The flower is relatively very large; the falls are rather longer than broad; the styles are bent down so as to be nearly horizontal, and the prevailing color, a dark grey, is produced by numerous veins and dots of a dark almost black-brown with a slight tinge of purple on a creamy white ground, which aquires a brownish hue owing to the difussion of color from the margins of the veins and dots. The hairs of the fall are black. As the flower withers the purple constiuent of the color becomes very prominent."

| Dykes in The Genus Iris 1913; " Description. Rootstock , a stout compact rhizome, with a reddish skin. Cultivated plants do not produce stolons but these might arise in poor soil. Leaves , 12 in. or more in length by 3/4-1 in. broad, of a distinctly yellowish green. Stem , 12-15 in. long, sheathed in 2-3 reduced leaves. Spathes, I-flowered, valves 3-4Â½ in. long, green or slightly flushed with purple. Pedicel , very short. Ovary , much rounded trigonal, with a slight groove on each face, passing into the tube without any marked constriction, 1 in. long. Tube , 1-1Â½ in., green, striped and mottled with purple in the upper part. Falls . The broad wedge-shaped haft expands gradually into the ovate blade and bears a very broad diffuse beard of brown-black hairs. Beyond this on the blade is a deep purple black velvety signal patch. The rest of the surface is of a dark grey colour, produced by numerous veins and dots of a dark black purple on a grey-white ground. Standards . Orbicular with a short haft, which bears on its inner side a number of scattered black hairs. The colour resembles that of the falls but the lines and dots are not so thick and the whole effect is therefore lighter. Styles , horizontal, sharply keeled, of a deep red-black colour. Crests , broad and low, sharply reflexed. Stigma , entire. Filaments , creamy, about half as long as the anthers. Anthers , creamy, very large, 1 in. long. Pollen , creamy. Capsule , 2-4 in. long, ellipsoid, tapering at either end, dehiscing below the apex. Seeds , globose or pyriform, dark red-brown with a conspicuous creamy aril (cf. Plate XLVIII, Fig. 8).Observations.This Iris has been in cultivation in Europe for more than three centuries, for it was brought from Constantinople to Vienna in 1573, and a very fair picture of it was published by Clusius in 1601 (cf. Clusius, Rar. Plant. Hist., pp. 217, 218 (1601)). It was moreover the first Iris to be described by Linnaeus in his list of the species.I. susiana can hardly be described as beautiful, though its flowers are undoubtedly striking. Owing to the fact that this Iris has long been cultivated in the South of France, it has become more nearly acclimatised to the conditions of existence in English gardens than any other Oncocyclus species. Instances are not unknown where plants have spread into large clumps and flowered well year after year. The best conditions would probably include heavy limestone soil and certainly a warm and sunny position, where the soil was usually rather dry. These conditions might possibly be obtained in the requisite soil under a conifer, whose branches overhung the Irises and yet did not allow water to drip upon them to any extent nor shade them from the sun.

Though the date 1753 goes with the description and the name susiana
for this iris; it was known in cultivation long before, as it was purchased by Tradescant for Hatfield House garden under the name of Susyand in 1611; syn. Mourning Iris; Iris de suses; Iris grandiflora,
Salisb.; Oncocyclus susianus
K. Koch; Iris punctata
Original form possibly extinct; forms in commerce possibly Iris sofarana
or Iris basaltica
. See Iris sofarana .
Although Iris susiana
may have been a distinct species, wild populations have disappeared, and cultivated forms appear to be forms of Iris sofarana
no varieties known.
