Cochliostema odoratissimum Lem. - syn. Cochliostema odoratum K. Koch & Bouche; Cochliostema jacobianum K. Koch & Linden - Commelinaceae 

"In the wild, plants grow as epiphytes; however, terrestrial plants are found on or around tree falls suggesting that these ground-dwelling plants had been growing epiphytically. One species, Cochliostema odoratissimum, is a tank-epiphyte, resembling certain bromeliads in this respect. This species also attains the greatest size for the genus, with its leaves reaching to 1 m in length, and plants sometimes reaching 2 m in height." [[https://en.wikipedia.org/wiki/Cochliostema]]

"This Commelinaceae emits a very distinct fragrance, which is composed of rosy-floral, ionone-floral and refreshing hesperidic notes and a high portion of indole. Especially worth mentioning is the occurrence of the (E)-2,3-dihydrofarnesal, which adds an attractive fresh aldehydic 'lily of the valley' -type note to this rich floral scent, and that of the corresponding alcohol rounding it off by a tender note of cyclamen." \\
Main components of the headspace were nerol (39.5%), indole (11.5%), (E)-geranylacetone (6.8%), (E)-2,3-dihydrofarnesol (5.3%), (E)-ocimene (5.0%), linalool (5.0%), citronellol (3.0%), geranial (2.0%), dihydro-β-ionone (2.0%), (E)-2,3-dihydrofarnesal (1.5%), and neral (1.0%). \\
