Taxonomy

The tropical ash was originally described as a variety of Fraxinus americana (white ash) by Theodor Wenzig in 1883[3] and was separated as a different species in 1907 by Alexander von Lingelsheim.[4]

Fraxinus uhdei is locally known as fresno blanco in Spanish; other English vernacular names include Hawaiian ash and Mexican ash.[2] The name Shamel ash refers to Archie Shamel, who introduced the trees to California in the 1920s.[5] The specific epithet uhdei refers to Carl Uhde, a German plant collector who explored Mexico in the 1840s.[5]
