Langdon's research focused on the stem anatomy of Cycas and Dioon spinulosum as well as the anatomy and taxonomy of floral species such as the family of Juglandaceae and Fagaceae.[1] While the cycas species was previously investigated, Langdon's research was the first to investigate its growth rings.[2] In a study, she also described the anatomy of the packing tissue of the genus Carya.[3] Her works were funded by grants from the National Research Council and the American Philosophical Society.[1]
