ABSTRACT:

Syngonium steyermarkii Croat is endemic to the Pacific slope of Guatemala and Southern Mexico at elevations above 1100 m. It was first collected by Dr. Julian Steyermark (Missouri Botanical Garden), who made three sterile collections of the species in three different Departments of Guatemala (Quezaltenango, San Marcos, and Suchitepequez) while collecting for the Field Museum in 1941 and 1942.
