The Gardeners' Chronicle 49: 362. 1911.
The Curtis's Botanical Magazine. tab. 8433 in 1912, gives the following information along with the color illustration.

"The handsome Iris here figured was discovered in Western Szechuan in 1908, where it was found by Mr. E. H. Wilson growing in thickets near Kuan Hsien at elevations of from 7,000 to 11,000 feet above sea level. The plant from which the material for our plate was obtained was grown by Mr. W. R. Dykes in his garden at Charterhouse, Godalming, from a seedling raised by Miss Wilmott in her garden at Warley Place, Essex. It came into flower towards the end of May, 1911. A freely floriferous species and at the same time one of the most richly colored of these now in cultivation, I. chrysographes promises to prove a favorite garden plant. As Mr. Dykes has pointed out in the Gardeners' Chronicle, the species is a member of the "Sibirica" group, and is closely allied to I. Forestii, Dykes, but differs in colour of flower and in habit; it also flowers somewhat earlier than I. Forrestii. Among the more familiar species in collections it also approaches rather closely to I. laevigata, Fisch., but may be at once distinguished by its narrower, more sharply pointed spathes. The rich dark purple flowers with their velvety texture render the plant a very conspicuous object; the colour is well set off by the central line and the broken flanking streaks of golden yellow. These flanking streaks vary somewhat in number and extent, sometimes they are almost absent and only the central golden yellow line appears. Another species closely related to I. chrysographes is I. Delavayi, Micheli, from Yunnan, which has, however, a different capsule and seeds, and as a garden plant is readily distinguished by its taller statue and by its blue purple flowers with white markings. Mr. Dykes finds that I. chrysographes is not difficult to grow in any soil that is fairly rich in humus and is not heavily charged with lime. It appears not to demand either the excessive moisture or the very retentive soil in which I. Delavayi best succeeds.

Description.---Herb; rhizome rather slender, giving off several rather slender unbranched stems, hollow with a narrow lumen, about 1 ¼--1 ½ ft. high, bearing 1-2 reduced leaves and 1-2 flowers. Leaves linear, much narrowed upwards, acute, curving outwards, 1 ¼-1 ½ ft. long, ¼-1/3 in. wide, green. Spathes narrow, green, acute, 2-2 ½ in. long. Pedicels 1-1 ½ in. long. Perianth with tube about 5 lin. Long; outer segments much deflexed; blade oblong- or almost obovate-elliptic, 2 in. long, 1 in. wide, brilliant dark purple-violet, velvety papillose, marked in the center with golden yellow lines and streaks; claw linear-oblong, 1-1 ¼ in. long, reddish purple, finely dotted with golden yellow; inner segments erect, oblong, obtuse, narrowed below into a claw, altogether 2 ¼- 2 ½ in. long, 4-5 lin. Wide, dark purple-violet. Style with deep purple arms, their crests with ovate blunt lobes. Stamens with filaments about 8 lin. Long, anthers 6 lin. Long. Ovary 8 lin. Long.
