An NYBG Internship Experience: Connecting the Dots to Understand Relationships between Living and Extinct Cycads

Cynthia Huyck is a former intern at NYBG’s Pfizer Plant Research Laboratory. She is completing her undergraduate degree at Sarah Lawrence College, concentrating in botany and Japanese.

In this image of a stained cross-section of a Cycas media ovule, the vascular bundles in the center are starting to divide into three separate bundles as opposed to two.

Editor’s Note: As the end of the academic year approaches, The New York Botanical Garden’s Plant Science and Conservation program will soon welcome a new class of summer interns. As described in this post, these internships offer valuable experience by allowing students to work closely with NYBG scientists on cutting-edge research.

I spent last summer and fall as an intern working with Vice President and Cullman Curator Dennis Stevenson, Ph.D., on the Gymnosperm Seed Evolution Project at The New York Botanical Garden. The goal of this project is to better understand the relationships among different gymnosperms based on their seeds and seed-bearing organs. My work focused on the anatomy of early phases of ovule development, with an emphasis on branching of the vascular bundles, which contain the specialized cells that transport water and nutrients throughout the plant. I used an anatomical approach because my work involved comparing extant and extinct cycads. Although we cannot extract DNA from the fossils, we can look for structural features in both the fossils and extant species in order to place our fossils on a phylogeny (evolutionary tree) and establish a minimum age for cycads.
