richly developed as in Fulvala, corresponding fairly well with the 
Petunia Violet of Ridgway, a shade differing from the Roods 
Violet of Fulvala mainly in having more grey in it. 
Both the species /ris fulva and I. foliosa and the three hybrids 
between them—Fulvala, Dorothea K. Williamson, and our own— 
are very fertile at the Brooklyn Botanic Garden. A large propor- 
tion of the flowers normally set pods in which are well developed 
seed. The seed also germinates quite readily, although it usually 
takes several months for the young seedlings to emerge from the 
soil. 
SEEDLINGS OF DoroTHEea K. WittiAMson.—lIn 1925 a flower of 
Dorothea K. Williamson was pollinated with pollen from this 
same variety and the ripe seed from the pod was carefully saved 
and planted the same fall. The seed germinated and several seed- 
lings were grown to the aeye ae stage. Four of these first blos- 
somed in 1928, and these same ones, with two additional plants, 
produced flowers in 1929. 
The plants were all more or less similar in their general features. 
They resembled somewhat closely the Jris foliosa grandparent. 
There were minor differences between the plants in the height, 
width, and color of the leaves. The flower stems were short, more 
or less zig-zag, and hidden, or nearly so, by the leaves. Most o 
the plants lacked the characteristic vigor of their immediate parent, 
Dorothea K. Williamson. None of them showed any approach to 
the tall slender habit of J. fulva. 
The most striking thing about all of these plants was the great 
variation in the size, shape, and color of the flowers. [ive distinct 
plants were numbered and described and colored figures of the 
flowers are shown in the plate. 
Plant No. 1.—TVhe flower of this plant shows marked similarity 
to that of its immediate parent, Dorothea K. Williamson, the parts 
having the same general shape and position. ‘The falls are rela- 
tively narrow and pointed; the standards are also narrow and 
lanceolate; the bases are white, this color extending part of the 
way up the central portion. The style-branches are white, or 
nearly so, except at the tips, where there are some purple areas 
on the crests. The color of both the falls and standards is slightly 
more blue-purple in tone as compared with Plant No. 2.
