the Nonea grew also the stronger for its struggle, the battle would 
still be about equal, until an "if" in the shape of some such an ac- 
cident as I have above illustrated should come in to the advantage of 
the victor. 
It seems to me that there is another side to the subject of the 
'* survival of the fittest " that we seldom have presented to our view.

Di 
centra aicullaria are systematically punctured by humble-bees; I 
have watched them in the process. Has this been noticed when the 
plants are growing wild? It sadly interferes with the very neat 
mechanism for cross-fertilization.

Abnormal Hepaticas. — The blossoming of Anemone Hepattca in 
Ross Park, near this city, this spring, is very varied and profuse. 
Among the myriads of plants, I have noticed the following abnor- 
malities: 
(i) Dozens of plants have very deep blue sepals with a white or 
light blue margin. All of these are absolutely stamenless, though pollen 
was found upon the stigmas, whither it must have been brought by 
insects. 
(2) Numbers of flowers were pure white, and all of these had nine 
sepals and bore — as far as the flowers were concerned— an exact 
resemblance to A. nemorosa. One monosepalous flower was found 
with six lobes, one of which was cleft to its centre, thus forming, with 
a stameniferous extra sepal, nearly an 8-sepaled specimen.

Tribute of Respect to Dr. Engelmann.— The following preamble 
and resolutions, indicative of the appreciation of the high scientific 
and personal character of the late Dr. George Engelmann, were 
unanimously adopted by the Botanical Section of the Academy of 
Natural Sciences of Philadelphia, April 14th, 1884, 
Whereas, the Botanical Section of the Academy of Natural 
Sciences of Philadelphia has heard with profound regret of the death 
of Dr. George Engelmann; therefore 
Resolved: We regard this as a calamity to Botanical Science and 
to those who were in any way associated with him in its study; also 
Resolved: That in his life he furnished an example of irCdustry 
in his profession, of devotion to science, of thoroughness in investi- 
gation, and of success in labor which will always command our 
admiration and respect; and be it further 
Resolved: That by his readiness to aid all who were seekers after 
the truths of nature, by the conscientious answers to the botanical 
questions referred to him, no less than by his goodness as a man, we 
believe he has attached many to the science in whose service he died. 
Resolved: That as a mark of respect to the memory of the 
deceased, these resolutions be entered upon the minutes of the Sec- 
tion, a copy be transmitted to his family, and also a copy of them
