Jumellea is an orchid genus with 55 species native to Madagascar, the Comoros, the Mascarenes, and eastern Africa. [1] In horticulture, it is often abbreviated Jum.

Contents

Etymology

It is named after Henri Lucien Jumelle, a French botanist. [2]

Ecology

Pollination

Jumellea exhibits the typical adaptions to pollination by hawk moths. However, also auto-pollination is known to occur in Jumellea stenophylla. [3]

Phylogeny

Jumellea is proven to be monophyletic. [4]

Jumellea is the sister group to Aeranthes . [4] [5] [6] Both genera together are the sister group to Angraecum : [6] [5]

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. [6]
