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]

	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.^[6]
