text: # Jumellea fragrans
  
  Jumellea fragrans, also known as faham, is a species of orchid in the genus Jumellea. It is native to the islands of Mauritius and Réunion.
  
  ## Ecology
  
  It grows as an epiphyte in the lowland rain forest up to 500 m above sea level.
  
  ## Description
  
  The species blooms in March-April with a single flowered inflorescence with 3 basal bracts. The flower has a spur of approximately 39 mm long and is pollinated by hawk moths.
  
  ## Taxonomy
  
  ### Differentiation from Jumellea rossii
  
  These two similar species can be confused. Jumellea rossii occurs at high altitudes, whereas Jumellea fragrans occurs at lower elevations. Three important diagnostic characters for species delimitation have been identified: The length of the spur, the leaf length, as well as the leaf width:
  
  | Species | Spur length | Leaf length | Leaf width |
  | - | - | - | - |
  | Jumellea fragrans | >30 mm | >85 mm | >14 mm |
  | Jumellea rossii | <30 mm | <85 mm | <14 mm |
  
  ## Phylogeny
  
  Jumellea fragrans is the sister group to Jumellea rossii. It is also closely related to Jumellea tenuibracteata, Jumellea francoisii, and Jumellea alionae, as can be seen in the following cladogram:
  
  ## Uses
  
  The fragrant leaves and flowers are boiled in hot water to extract its aromatic qualities. This is used to flavour rum on Reunion Island. Other uses that have fallen out of favour include digestive aid, remedy for respiratory disease, ice cream and custards. The plant's use for medicinal purposes on Mauritius is thought to be critically endangered.
  
  ## Conservation
  
  It is threatened due to unsustainable overcollection in wild habitats and lack of agricultural production. It is recommended to categorize Jumellea fragrans as vulnerable (VU) under the IUCN Red List criteria.
  
  ## Physiology
  
  Coumarin, and two groups of diterpenes (kaurenes, phytadienes) have been isolated from this species foliage.
