 II Flowers were all cleistogamic.

 ** Fifteen more buds. 



It was afterwards a matter of regret that all the cleisto- 

 gamic flowers on the lower part of axis, as well as those on 

 the upper part, had not been counted on the plants whose 

 records were kept. 



A series of observations that gave some idea of the 

 approximate numerical relation of all flowers, was made 

 during a succeeding season. A short resume of the work 

 of the two years is next given. 



In September, 1899, plants of Epiphegus were examined 

 in order to ascertain the number of chasmogamic flowers 

 produced. An inflorescence shows ordinarily from fifty 

 to seventy-five flowers, and quite often over one hundred. 

 In several cases one hundred and forty were counted. In 

 1902 there was a marked decrease in the number of chas- 

 mogamic flowers borne. The character of the season may
