Taxonomy
The genus is named in honor of Timothy Plowman (1944–1989), an American ethnobotanist best known for his intensive work over the course of 15 years on the genus Erythroxylum, and the cultivated coca species in particular.[2] It was first described and published in Syst. Bot. Vol.29 on page 316 in 2004.[1]
