# 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.

## Ecology
### 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.
