Jumellea alionae P.J.Cribb, herbarium sheet isotype

Jumellea is an orchid genus with 55 species native to Madagascar, the Comoros, the Mascarenes, and eastern Africa.

Taxonomy

It was described by Rudolf Schlechter in 1914.

Etymology

It is named after Henri Lucien Jumelle, a French botanist.

Phylogeny

Jumellea is proven to be monophyletic. Jumellea is the sister group to Aeranthes. Both genera together are the sister group to Angraecum:

Aeranthes

Jumellea

Angraecum

Angraecum evolved into a separate lineage about 9.12 million years ago, and the genera Jumellea and Aeranthes separated about 9.55 million years ago. This means these genera date back to the Miocene.

Species

Distribution and habitat

It is native to the Comoros, Kenya, South Africa (KwaZulu-Natal, Northern Provinces), Madagascar, Malawi, Mauritius, Mozambique, Rodrigues, Réunion, Tanzania, and Zimbabwe.

Ecology

Jumellea exhibits the typical adaptions to pollination by hawk moths. However, also auto-pollination is known to occur in Jumellea stenophylla.
