Dragon Trees and Mother-in-Law's Tongues

The most significant recent studies of Dracaena were undertaken in Wageningen by J.J. Bos. He established major collections of literature, herbarium specimens and living plants, and published regional treatments of African Dracaena (Bos 1984, 1992, Bos & Teketay 1997). A Flora of Somalia treatment for both genera was published by Thulin (1995). Sansevieria was monographed by Brown (1915), whose research began the sizeable RBG, Kew living collection. Most recent research on the species of the genus has been by succulent plant enthusiasts and researchers such as Chahinian and Newton.
