There is no denying that roots are one of the most important organs on a plant. However, unless its an epiphyte, root activity takes place underground, largely out of site and out of mind. This has not stopped my guest today from trying to understand the origin and evolution of these amazing structures. Joining us from Magdalen College in the UK is plant evolutionary biologist Dr. Sandy Hetherington whose work spans hundreds of millions of years of root history. Join us as we explore the early days of root evolution and learn how things like fungal symbionts and a lack of organic matter set the course for root evolution. As you will hear, this work also relies heavily on museum and herbarium collections, underscoring the importance of preserving these important data goldmines.

Phenology, population size, distribution, genetic diversity - these are just some of the data locked up in herbaria around the globe. My guest today is Katelin Pearson and she has been working hard on making sure herbarium data are as available as they can be to everyone from scientists to artists, and even the general public. As you will hear, we herbaria succeed, so do the plants they help understand.

Pine cones are fascinating structures. These scaly organs are the female reproductive structures of conifers. As children we collect them, throw them, decorate them, and even smother them in peanut butter and seeds to attract birds. My guest today takes pine cone collecting to a new level. Renee Popp is retired botanist from the US Forest Service and is the creator of Project Pine Cone. Renee's goal is to amass a collection of cones from every species of pine on the planet. She uses her collection to teach children and adults about not only pines, but also bigger ideas in botany and ecology. Her stories are inspiring in a big way and I know you are going to enjoy this conversation. The episode was produced in part by Gregory, Mark, Allen, Desiree, Sienna, Laura, Margie, Troy, and Bryan.
