Crabapple trees described in
Plant Names and Plant Lore among the Pennsylvania Germans (1927)
By David Lick and Thomas Brendle:

  Above: The head of this book’s publication committee was Dr. B. F. Fackenthal, Jr.. He also was chairman of the F&M College Board during that time. The college’s Shadek-Fackenthal Library is named for him. The book was published by the Pennsylvania German Society. Dr. Fackenthal was president of that historical society in 1913. Records of the society are archived in F&M College’s special collections.
The book was printed in Lancaster by the Lancaster Press. That building today is the condo building named The Lancaster Press Building, on N. Duke St. and Lemon St.

 Above: Crabapple tree on the Klauder-Apple Walk. Meyran Hall is in the background. The arboretum map does not identify the cultivar names of the campus crabapples.
Note: Lick and Brendle classified the native Pennsylvania crabapple as Pyrus coronaria. But this species has been reclassified and is now correctly named Malus coronaria in accordance with the latest taxonomic revision.
