Chaetachme is a monotypic genus of flowering plants native to eastern and western Africa, including Madagascar,[3] containing the single species Chaetachme aristata. Its English common name is thorny elm,[4] and it is known as muyuyu in Kikuyu.[5] Traditionally placed in the Elm family, it is more recently placed in the family Cannabaceae, thought to be possibly closely related to Celtis.

Chaetachme aristata is a shrub or small tree growing up to 10 meters tall. It has drooping, angular branches covered with spines up to 3.5 centimeters in length. The lance-shaped leaves are up to 11 centimeters long by 5 centimeters wide, pointed at the tip and smooth or serrated on the edges. The shrub is dioecious and sexually dimorphic, with male and female flower types borne on separate individuals,[3][6] although it may also be monoecious.[7]

This shrub is host to the mirid bug Volumnus chaetacme.[8]

The spiny branches of the shrub are used as fences in African villages.[5][9]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
