Cercis canadensis L. Redbud. Common all around the area and in the northern 

 section but very rare in the southern section. A satisfactory hypothesis to 

 account for this and some similar anomalies is beyond the imagination of the 

 visiter, but the absence of the redbud is exceedingly striking in the spring, 

 when a single flowering tree can be seen for miles, so that there can be no 

 question of the fact. No specimens.
