Episode Description from the Publisher

Episode 20 and we finally have an aroid taxonomist in the room. Marco Cedeño Fonseca is a Costa Rican botanist who did his master's on Monstera at the University of Costa Rica and just finished his PhD at the Berlin Botanical Garden — as in, he got the title the day before we recorded and told us at the very end.News: the Thomas B. Croat Aroid Garden was inaugurated in Tabasco, Mexico. A 5-meter plant gets a strong opinion out of Marco about plastic plants in Costa Rica. And a new Typhonium was named in Thailand, which sends us down a hole about why genera keep getting split.Interview: How a forestry student ended up building a greenhouse in his apartment to germinate Monstera seeds; why juveniles are the taxonomic problem; the Monstera everyone calls esqueleto that has never been documented in the wild; what a Costa Rican field botanist does all day in a German DNA lab; and the one Monstera he's never seen.Hot or Nah: Dendrobium Kirkland Nixon 'Bredren', Anthurium warocqueanum × veitchii, Dionaea muscipula 'Medusa'.Rate That Weird Plant: Gethyllis namaquensis, Tecticornia verrucosa, Ranunculus semiverticillatus.Follow Marco on Instagram: @marco_vcfRead about the Croat garden on the IAS Substack: substack.com/@aroidsocietyNext episode: Probably live from the IAS Tropical Plant Expo in Miami.Prop Culture is brought to you by Hortikult's Plant Provenance, PlantCard.io, Plant My Event, Webaceae, and Gifts for Plant People.
