Four species of Philodendron sect. Macrobelium, namely P. huaynacapacense from Peru and Bolivia, P. rimachii from Peru, P. ushanum from French Guiana and P. wadedavisii from NW Brazil and SE Colombia, are described as species new to science and illustrated.
Investigations with Philodendron at the Missouri Botanical Garden have yielded four new species from South America, while a considerable number of other species there remain in the process of being analysed and described. Nearly every school year the first author is blessed with a gifted Washington University student who chooses to take his or her rotation in his laboratory. At Washington University, each graduate student in biology is expected to do three such internships with different department members and some students are attracted to the training he offers in systematics. The latest is the co-author of this paper, following in the footsteps of other graduate or undergraduate students from Washington University, St Louis University, Grinnell College, the Universidad San Carlos and the University of Milwaukee. They have learned in the aroid working group at the Missouri Botanical Garden to enjoy aroids, to understand their complex morphology using both living and dried specimens, to make detailed descriptions, to write taxonomic keys, to prepare florulas, to write a paper for publication and to share in the publication of new species. Among those who have shared this experience are Nancy Lammert, Douglas Hayworth, Patricia Davila, David Mount, Tom Stiebel, Cavas Engineer, Anne Swart, Alicia Shah, Juan Chaparra, Courtney Finch, Jorge Lingan and Monica Carlsen.
