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

  Above: Lick and Brendle’s Plant Names book includes Southern Catalpa, Catalpa bignonioides. The publication includes no references to Northern Catalpa, Catalpa speciosa. Both species have long seed pods that look like beans. Presumably the northern species had the same dialect name Buhne Bawm (Bean Tree).
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.
