Jumellea



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

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

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

Phylogeny
Jumellea is proven to be monophyletic.

Jumellea is the sister group to Aeranthes. Both genera together are the sister group to 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.
