that of J. fulva. For the young growths push up soon after the 
flowers are over and are 4 or 6 inches long in winter, while those 
of I. foliosa are still only 1 in. long, and those of J. fulva a foot 
at least. “The stem is more like that of J. fulva than like that of 
the pollen parent, but it is sturdier. The flowers are of the shape 
of J. foliosa, with perhaps more rounded segments, and the colour 
is distinctly a compromise between the terra cotta of J. fulva and 
the blue-purple of J. foliosa. The figure of a flower of J. fulvala 
shows the form in which the influence of the colour of J. fulva is 
most apparent. I have also from the same pod of seed other 
plants in which the shade of colour has distinctly more of the blue- 
purple of [. foliosa in it.” 
In 1918, Mr. E. B. Williamson listed a new garden variety of 
iris under the name of Dorothea K. Williamson, which was ob- 
tained from hybridizing Iris fulva with I. foliosa. This plant is 
now well known in our gardens, since it has exceptional qualities. 
It is a very vigorous grower, and produces flowers in great abun- 
dance. The leaves are taller than those of either J. filva or I. foli- 
osa; the stems are longer than those of /. foliosa, and bear several 
flowers, which may be open at the same time; the stems, however, 
do not exceed the leaves in height. 
The falls remain nearly horizontal. They possess the quality 
of an iris flower which is described as “ substance.” The stand- 
ards spread out in about the same plane as the falls. The color 
of the flowers matches fairly closely the Hyacinth Violet of Ridg- 
way, on Plate 11 of his Color Standards and Nomenclature. The 
flower differs from Fulvala in that the falls are more pointed and 
in the bluer tone of the color. The color of Fulvala corresponds 
very closely to Roods Violet on Plate 11 of Ridgway. 
We have also crossed these two species using, however, the 
pollen from Jris fulva on the stigma of J. foliosa. The original 
crosses were made in 1924 and, from the seed obtained, several 
seedlings were grown. These first flowered in 1927. All the 
plants had the same general appearance so far as shape and color 
of the flower were concerned. They manifested a somewhat less 
rank and vigorous growth as compared with either Fulvala or 
Dorothea K. Williamson. In shape, the flower was very similar 
to that of Fulvala, the parts, however, being slightly smaller, and 
the tips of the falls a little more pointed. The color was not so
