Filaments , about equal to the anthers, but usually rather shorter, greenish. 
Anthers, long and narrow cream, the sacs being widely separated. 
Pollen, yellowish white, much more sharply pointed than that of /. hexagona. 
Capsule, globular, more than an inch in length, and nearly as wide. 
Seeds, resembling those of /. hexagona, but slightly smaller. 
Observations. 
This is the Iris that has been known in gardens for some years as /. hexagona var. Lamancei. 
It would perhaps have been better to keep this varietal name, but unfortunately, although Lora S. La 
Mance’s note in Garden and Forest (l.c.) states that the plant was named by Mr J. N. Gerard, no 
description was apparently published. Even though there is no absolute proof that Gerard's Lamancei 
and Mackenzie and Bush's foliosa are identical, there can be little doubt that both names were given 
to the same plant. 
/. foliosa is well named, for it almost hides its curiously flexuous stems among the luxuriant 
foliage, which is more glaucous and less distinctly that of an aquatic Iris than the leaves of /. hexagona. 
Its rhizomes spread very quickly, and need to be transplanted soon after the flowers have faded every 
two or three years. The soil should be rich in humus, and not too dry in the spring and early 
summer. 
The question of the relationship of /. foliosa to I. hexagona has already been discussed under the 
Observations on the latter, and it only remains to add here that the few seedlings of I. foliosa that 
I have been able to raise have reproduced the dwarf habit and other characteristics without any 
noticeable variation. 
A very beautiful white-flowered form has lately been introduced into our gardens, but it is not 
known whether this was found wild or whether it is of garden origin. The white flowers are some- 
what faintly tinged with pale purple, and in this respect resemble the albino forms of /. laevigata and 
/. sibirica. 
The pollen of I. foliosa has been used to fertilize I. fulva, and the description of the resultant 
I. fulvala (see Plate XXI) will be found in the note on the hexagona group (see p. 81).

/. fulva Apogon ; /. hexagonae haud dissimilis ; sed segmenta interiora truncata, emarginata, ex-

Description . 
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 in. long. 
Ovary, six-ribbed, as in spuria, but with the ribs at more equal intervals, shorter than the tube, green. 
Tube, yellowish, f — 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^ in. by 1 in.
