Lignum rhodium

Lignum rhodium is a common name for several plants and may refer to:


 * Amyris balsamifera
 * Convolvulus floridus
 * Convolvulus scoparius
 * Rhodiola rosea

- all of which have a rose-like fragrance, due to their containing certain essential oils - hence the common name combining Latin and Greek elements and signifying 'rose(-scented) wood'.
