_ Hybridization work with Irises is not a fertile soil for scientific 
investigation, practically all breeders are working toward garden 
results rather than toward scientific proof. We are dealing with 
relatively small numbers of any one parentage, and with very large 
numbers of inherent factors and, consequently, we must draw infe- 
rences as to certain fenilencies revealed by inadequate records 
- rather than attempt to state proved facts. 
As I think that inherent characters that influence the distribution 
of color should be considered in the formation of a classification, 
I shall now present the deductions that I have drawn from my 
familiarity with the work of Miss Grace Sturtevant and A. J. Bliss. 
_ Both these hybridists plan and record their experiments in hybridi- 
zation. Miss Sturtevant is working chiefly to develope strains of 
yellow pallida and cypriana types of height and habit, and Mr. Bliss 
has done the most with plicala and his ‘‘ Dominion race ’’, but 
both have produced improvements in many other types and colors. 
I wish that I might forsee to what extent your hybridists would 
agree to the following statements. 
Self (standards and falls of apparently the same color, and 
unmarked). A dominant character in lavenders of pallida origin, a 
recessive in yellow and white. 
Plicata (standards marked) a recessive character, the ground color 
variable, the markings also variable, sometimes bronze, but never 
yellow. 
Veined bicolor (venation present on blade of falls) ground of any 
color, venation red or purple-toned, sometimes bronze, but never 
yellow. 
Velvely bicolor usually, but not always, due to veins becoming 
confluent on the fall. (Jacquesiana and Dr. Bernice are from their 
appearance of similar make-up, but the first gives selfs in the first 
generation, the other bicolors, often veined bicolors. Hence; this 
quality may be a separate inherent factor). 
Solid bicolor derived from many sources, colors often blended, 
but rarely dominantly yellow. 
These distributions of color seem to be inherent, as well as appa- 
rent characters, and permit of sufficiently accurate definition to 
classify all possible combinations of color as found in garden Irises. 
The great majority of Iris varieties are either lavender selfs, or 
solid, or veined bicolors, the small minority (at present) white, or 
yellow selfs, plicatas, or velvety bicolors. Presumably, this mino- 
rity represent recessive characters that, as it happens, are fairly 
closely linked with certain habits of growth or form of flower. For 
example, our yellow variegata lack height and size, qualities which
