"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 

 tvpical flowers. The remaining fifteen hundred are divided 

 among the dift'erent colors as follows: white, 538, or 35.80% of 

 1500; violet, 170, or 11.33%; purple, 193, or 12.86%; blue, 136, 

 or 9.06%o; green, 160, or 10.66%,; vellow, 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:
