| Curtis's Botanical Magazine table 1496. 1812, Desc. Rootstock assurgent about half an inch in diameter; leaves of a bright green colour, equitant, sheathing, those in the sterile fascicles, as throughout the genus, broader and longer than those in the fertile ones, about two feet high and more than half an inch across ; stem about the thickness of an ordinary quill and usually one-branched; corolla about three inches long, scentless; tube greenish; segments on their first development hanging loosely down, afterwards extending themselves somewhat horizontally, as in the coloured flower of the annexed engraving, of a tawny or copper colour with purple veins; by the asistance of a magnifying glass, that part of the outer ones which lies under the sligmas will be found to be covered with a short pubescence, resembling that on the skin of a peach, especially at the veins; this is likewise the case in versicolor and virginica although relatively termed beardless.
An unrecorded and lingular species, differing from any known to us in the colour and inflexion of the corolla. Found spontaneous on the Banks of Mississippi, in low grounds not far from the town of New-Orleans. Introduced into this country in 1811 by Mr. Lyon, a very intelligent and industrious collector of North- American plants. Hardy. Blossoms in June. Seeds freely, and is easily propagated by dividing the rootstock. G.

I. fulva Apogon; I. hexagonae haud dissimilis; sed segmenta interiora truncata, emarginata, exterioribus subaequalia Colore etiam omnino differt.
Rootstock , a stout rhizome, showing ring-like marks where the leaves of former years have been attached, of a pale greenish brown.
Leaves , bright green, ensiform, the upper third reflexed, 2 ft. or more long by 1 in. wide; the plant is practically evergreen.
Stem , 2 ft. or more in height, bearing a terminal head of 2 flowers, and 2 side-flowers set in the axils of reduced leaves.
Spathe valves , narrow, pointed, 2-4 in. long, the outer sheaths being• green and persistent, unequal.
Pedicel , about 1 1/2 in. long.
Ovary , six-ribbed, as in spuria, but with the ribs at more equal intervals, shorter than the tube, green.
Tube , yellowish, 3/4--1 in. long, quite hollow right down to the ovary.
Falls , oblanceolate cuneate, of a deep terra cotta colour, with veins of a deeper colour, especially along the centre of the blade, 2 1/2 in. by 1 in.
Standards , broad, truncated, deeply emarginate, of the same colour as the falls, 2 in. by 1 m. Styles , short, under r in. long, convex, unkeeled.
Crests , small, rounded, triangular, with minutely serrate edge.
Stigma , with two pointed teeth, not prominent.
Filaments , yellowish, short.
Anthers , cream, reaching stigma.
Capsule , very large, 2 in. long by an inch or more broad. Six-ribbed, with 3 broad and 3 narrow surfaces, each of which bears a slight ridge down the centre, remaining green, even when the seeds are ripe (see Fig. 10).
Seeds , with a thick spongy covering, irregular, with flat sides, very large, 1/4-3/8 in. in length (see Plate XLVIII, Fig. 3).
This Iris stands quite alone in the colour of the flowers, which is bright copper or terra cotta (see Plate XXI). Another curious feature is that, although when the flower first opens the segments all droop as in the drawing, yet on the following days they become much less pendulous, though still spreading rather than erect.
Herbarium specimens of this Iris are only with difficulty distinguished from examples of I. hexagona, unless it is possible to see the shape of the standards, which in I. .fulva are much broader and more obtuse, or the very narrow, short style-branches, and minute crests.
The leaves of this Iris show distinctly by their structure that it is an aquatic species, but it remains flowerless, if treated as such in England. It requires here a somewhat dry and warm position in rich light soil. It should be transplanted soon after the flowers have faded, and is much hardier in the climate of the greater part of England than is I. hexagona.

| Distribution: The distribution of the species gives clues as to its cultural requirements, although plants in cultivation can often tolerate a wider range of variables:
The species is found in the following region:

Prefers moist soil, but can be grown in good garden soil, well-drained and flourishes in full sun to part shade. Copius water during bloomseason. See Cultivation of Louisiana Irises
