The members of the genus Griffinia are tropical, bulbous plants which grow in high levels of humidity. The leaves are green, petiolate, elliptical, sometimes with white speckles on them. The flowers are typical for the tribe - lilac or blue colored (although there are also white - colored species) and collected into an umbel. Many of the members in this genus are endangered because of the deforestation of their habitat.[3]

Taxonomy

Griffinia Ker Gawl. was published by John Bellenden Ker in 1820 with Griffinia hyacinthina (Ker Gawl.) Ker Gawl. as the type species.[4] The genus Hyline Herb. published by William Herbert in 1840 is now a synonym of Griffinia Ker Gawl.,[2] but it was retained on the subgeneric level as the subgenus Griffinia subg. Hyline Rav. published by Pedro Felix Ravenna in 1969.[4] The genus Libonia Lem. published by Charles Antoine Lemaire in 1852 is a synonym of Griffinia Ker Gawl.[2]

Subgenera

The genus Griffinia is divided into Griffinia subg. Hyline Ravenna, in which only Griffinia gardneriana (Herb.) Ravenna and Griffinia nocturna Ravenna are placed, as well as the autonymous subgenus Griffinia subg. Griffinia, which includes all other species.[4]

Several unplaced names exist:

  • Hyline paraensis Ravenna was published by Pedro Felix Ravenna in 2003.[6]

Conservation

Griffinia intermedia is categorized as endangered (EN) by the IUCN Red List of Threatened Species. It is only known from two locations, in which the species, as well as its habitat is continually declining.[7] An initiative has been taken to replicate the fragrance of Griffinia gardneriana, which is threatened with extinction, for the creation of a perfume. The sale of the perfume is meant to financially contribute to the conservation effort for this species.[8]
