Fraxinus uhdei, commonly known as tropical ash or Shamel ash, is a species of tree native to Mexico and Central America.[2] 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.[2]

Like other species in the section Melioides, Fraxinus uhdei is dioecious, with male and female flowers produced on separate individuals.[3]

Taxonomy[]

The tropical ash was originally described as a variety of Fraxinus americana (white ash) by  [es] in 1883[4] and was separated as a different species in 1907 by Alexander von Lingelsheim.[5] The specific epithet uhdei refers to , a German plant collector who explored Mexico in the 1840s.[6]

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 , who introduced the trees to California in the 1920s.[6] It is known as Urapan in Colombia, where it was introduced in the 1950s.[7]

Ecology[]

A dieback caused by a phytoplasma was recorded in Colombia and Ecuador in 2004.[7]
