base. The style-branches are greenish white towards the base, 
with the large crests pale bluish. The flower has been illustrated 
by Dykes in The Genus Iris (Plate 20), and by Small in Addisonia 
(Vor, Plate 215.1024), 
The ovary of /ris foliosa is six-angled, or hexagonal, due to the 
longitudinal ridges. The mature capsule or pod is nearly spheri- 
cal, about an inch in diameter; it contains relatively few seeds, 
which are quite large, more or less irregular in shape and size, with 
a thick corky covering. They are very similar in appearance to 
those of J. fulva. 
Tris foliosa is a more northern species than J. fulva, but the two 
overlap in a part of their area. The former is doubtless widely 
distributed in the valley of the Mississippi and its main contribu- 
taries. Waller, in the Ohio Journal of Science (31: 38, 1931), 
records it as widely distributed in Ohio. He states that the habitat 
of the plant is the small stream terraces, succeeding well in partly 
shaded positions. This iris also differs from J. fulva in mani- 
festing a very marked winter habit. The leaves die down in the 
fall, and the new ones grow very little, if at all, until the following 
spring. In J. fulva, however, the new leaves push up in the 
autumn and may be of a considerable size during the winter period. 
Hysrips oF Iris Futva anp I. Forttosa.—Apparently, Dykes 
was the first one to hybridize these two species, taking the pollen 
of Iris foliosa and placing it upon the stigma of J. fulva. From 
the resulting seeds he grew several seedlings, and one of these he 
called J. fulvala, the name being made up from fulva and lamancet, 
According to his description, the color of J. fulvala was, “a rich 
velvety, reddish—almost crimson—purple, becoming yellow to- 
wards the center of the flower, the falls bearing a central, deep 
yellow slightly-raised ridge, which is distinctly pubescent.” Ac- 
cording to his note in the Gardners’ Chronicle (48: 2, 1g10), it was 
not until rg10 that the seedlings flowered. From the same pod of 
seed he obtained another plant which produced flowers of a deep 
blue-violet color. 
In his The Genus Iris, published in 1913, Dykes gives a colored 
illustration on Plate 21 of the flower of Jvis fulvala, and describes 
the plant, ‘as a compromise between the features of the two par- 
ents. Thus the foliage neither dies away entirely in autumn like 
that of 7. foliosa, nor remains green and of considerable length like
