The Apogon Section 
Standards, broad, truncated, deeply emarginate, of the same colour as the falls, 2 in. by J in. 
Styles, short, under 1 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. 
Pollen, cream. 
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, p. 81). 
Seeds, with a thick spongy covering, irregular, with flat sides, very large, $ — | in. in length (see 
Plate XLVIII, Fig. 3). 
Observations. 
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 /. 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. 
XII. I. ensata. 
This widely distributed Asiatic species seems to stand so entirely alone as to demand separate 
treatment. Its peculiarities will be found in the Observations at the end of the account of the species. 
The most striking features are the long, narrow ovary and capsule, and the extremely short perianth tube.
