Iris bungei Maxim., Bull. Acad. Imp. Sci. Saint-Pétersbourg, sér. 3, 26: 509 (1880).
Dykes in The Genus Iris; 1913;

Description, taken chiefly from the Przewalski specimen at Kew, quoted by Maxim.
*Rootstock* , a slender rhizome growing in very crowded tufts.
*Leaves* , narrow, linear, about a foot long, flushed with purple at the base.
*Stem* , 3-6 in. long, clothed in one or two narrow leaves, the uppermost rising to the top of the spathes.
*Spathes* , 3-4 in. long by ¾ in. wide at the centre, ventricose, with parallel fibres, without the network of cross fibres found in I. ventricosa, 2-flowered.
*Pedicel* , very short.
*Ovary* , 6-ribbed.
*Tube*, 1½-2½ in.
*Falls* , panduriform, pale blue, much veined, the obovate blade being shorter than the haft.
*Standards* , of a deeper shade than the falls, equal in length to them and sometimes slightly broader, oblong spathulate.
*Styles* , narrow, only half the width of the standards.
*Crests* , linear.
*Anthers* , reddish.
*Capsules* , 3 in. long.


This Iris comes between I. tenuifolia, from which Maximowicz omitted to differentiate it, and I. ventricosa. From the former it is separated by the rigid ventricose spathes, which however are covered not with netted fibres, as are those of I. ventricosa (see Fig. 3), but with close parallel ribs. It has never apparently been in cultivation.
