Fraxinus uhdei, commonly known as tropical ash or Shamel ash, is a species of tree native to Mexico and Central America.[3] It is commonly planted as a street tree in Mexico and the southwestern United States. It has also been planted and spread from cultivation in Hawaii, where it is now considered an invasive species.[3]

Like other species in the section Melioides, Fraxinus uhdei is dioecious, with male and female flowers produced on separate individuals.[4]

Taxonomy

[edit]

The tropical ash was originally described as a variety of Fraxinus americana (white ash) by Theodor Wenzig [es] in 1883[5] and was separated as a different species in 1907 by Alexander von Lingelsheim.[6] The specific epithet uhdei refers to Carl Uhde, a German plant collector who explored Mexico in the 1840s.[7]

Fraxinus uhdei is locally known as fresno blanco in Spanish; other English vernacular names include Hawaiian ash and Mexican ash.[3] The name Shamel ash refers to Archie Shamel, who introduced the trees to California in the 1920s.[7] It is known as Urapan in Colombia, where it was introduced in the 1950s.[8]

Ecology

[edit]

A dieback caused by a phytoplasma was recorded in Colombia and Ecuador in 2004.[8]
