blooming as spring, summer and fall. In many cases the period 
of blooming extends through two seasons and often through all 
three. A few plants, such as Taraxacum, were found to be in 
bloom practically throughout the entire year. In keeping a 
record of the various colors, for the sake of convenience nine 
general headings were used. These are white, violet, purple, 
blue, green, yellow, orange, red and pink. Many of the species 
studied produce flowers of more than one color, though in most 
cases the variation is confined to different shades or tints of the 
same color. In many of the species that typically produce 
bright colored flowers occasional white flowers are found. Exam¬ 
ples of this are Mertensia and the Giant Habenaria, the flowers 
of the former being typically blue and those of the latter violet. 
No note was taken of these occasional white flowers, as they 
were thought to have been caused by exceptional conditions. 
About two thousand angiosperms were examined, which 
includes practically all in the Ohio flora. Of these about five 
hundred were discarded, being grasses, sedges, etc., without 
typical flowers. The remaining fifteen hundred are divided 
among the different colors as follows: white, 538, or 35.86% of 
1500; violet, 170, or 11.33%; purple, 193, or 12.86%; blue, 136, 
or 9.06%; green, 160, or 10.66%; yellow, 380, or 25.33%; 
orange, 21. or 1.4%; red, 70, or 4.66%; pink, 160, or 10.66%. 
Of the fifteen hundred plants with typical flowers, 1040 
have conspicuous flowers and the remaining 460 inconspicuous. 
Eight hundred and three of the species with conspicuous flowers 
are native and 237 introduced; of the inconspicuous 350 are 
native and 110 introduced. 
With regard to color the record for these two divisions is as 
follows:
