Micheli in Revue Horticole 1895, p. 399, fig. 128, 129.
Sir Joseph Dalton HookerIris delavayimakes the following notes in Curtis's Botanical Magazine ., illustrated in color;

"As pointed out by its author, Mr. Micheli, Iris Delavayi is closely allied to I. sibirica, which has a very wide range, from Central and Southern Europe to Eastern Siberia and Japan. No further evidence of this is necessary than a reference to the figure of the latter plant at tab. 50 of this work. The differences indicated by Mr. Micheli are, that in I. Delavayi the peduncle is longer than the leaves, the spathes are foliaceous, not scarious, the flowers are longer pedicelled, the tube of the perianth is longer, and the capsule larger and triquetrous. Of which characters, however, that of the longer pedicel does not hold good. It is also very near the Japanese I. laevigata, Fisch & Mey. (I. Kaempferi, Sieb.), to which I. sibirica, var. sanguinea, Ker (I. sibirica, var. orientalis, Baker in Journ. Linn. Soc. Bot. vol. xvi. (1878) p. 139), tab. 1604 of this work is referable, in which the spathes are herbaceous, and perianth tube long.

I. Delavayi is a native of marshes in the Yunnan province of China. It was introduced into the Jardin des Plantes in 1889 by seeds sent by the Abbé Delavay. The specimens figured here are of plants raised from seed presented by Mr. Micheli to the Royal Gardens, which flowered in the open air in October, 1898; they are considerably taller and stronger than those described in the Rev. Horticole, and differ from the description there given in the crests of the stigmas being orbicular (not deltoid).

Descr.-Rootstock stout, creeping. Leaves two to two and a half feet long, by one half to two-thirds of an inch broad, strict, erect, narrowly linear, acuminate, strongly ribbed. Peduncle longer than the leaves, erect, flexuous, with two or three very narrow leaves, forked at the top. Spathes two to two and a half inches long, lanceolate, herbaceous, green, with scarious tips. Pedicels about as long as the spathes. Perianth two to two and a half inches across the segments, tube half an inch long; outer segments recurved, limb oblong, obtuse, deep violet blue, with tortuous white streaks in the lower half; claw as long as the limb, green, with violet white-spotted wings; inner segments erect, oblong-lanceolate, sub-acute, paler violet. Anthers linear, yellow; stigmas oblong, pale, violet, crests orbicular, crenulate. Capsule two and a half inches long, triquetrous."
