LaDema Mary Langdon (born January 3, 1893 – died April 1977) was an American scientist. She was a botanist, which means she studied plants. LaDema was famous for her work on how flowers and plants are built inside.
She also studied how plants are grouped (taxonomy) and how they grow from tiny beginnings (embryology). She looked at plants like Juglandaceae (walnut family) and Fagaceae (beech family). She also studied special plants called Cycas and Dioon spinulosum.
LaDema was a member of the American Association for the Advancement of Science. She also taught at Baltimore Junior College and Goucher College. She earned her first degree from Oberlin College. Later, she got her advanced degrees from the University of Chicago.
Studying Plant Parts
LaDema Langdon's main research was about the inside parts of plants. She looked closely at the stems of Cycas and Dioon spinulosum. She also studied the structure and grouping of flowering plants. These included the walnut family (Juglandaceae) and the beech family (Fagaceae).
Uncovering Plant Secrets
Scientists had studied Cycas plants before. But LaDema Langdon was the first to look at their growth rings. These rings can tell us how old a plant is, just like tree rings.
She also described the anatomy of the "packing tissue" in a type of plant called Carya. This tissue helps support the plant. Her important work was supported by grants. These grants came from groups like the National Research Council and the American Philosophical Society. These groups help scientists do their research.
