Cymbopogon nardus, common name citronella grass, is a species of perennial aromatic plant from the family Poaceae, originating in tropical Asia. C. nardus cannot be eaten because of its unpalatable nature and is an invasive species that renders pastureland useless, since cattle will starve even in its abundance. It is the source of an essential oil known as citronella oil, which is widely used for its natural insect-repelling properties. Essential oils are extracted from the aerial parts and applied topically or slowly burned (e.g. in a "citronella candle") as an insect repellent,

Barbeya is the only genus in the family Barbeyaceae, and has only one species, Barbeya oleoides. It is a small tree native to the mountains of Somalia, Ethiopia, and the Arabian Peninsula.

Barbeya oleoides has opposite, oblong-lanceolate, simple leaves with entire margins. Plants are dioecious, with male and female flowers on separate trees. The family Barbeyaceae is closely related to its ecological associate on the Horn, the family Dirachmaceae.

Trillium rugelii is a species of flowering plant in the family Melanthiaceae. It is endemic to the southeastern United States. Its white flower is typically found nodding beneath the leaves, hence it is known as the southern nodding trillium (not to be confused with Trillium cernuum, which also goes by that name). The specific epithet rugelii honors Ferdinand Rugel, a botanist and plant collector who collected plant specimens throughout the southeastern U.S. during the period 1840–1848. Although the species is apparently secure across its range, statewide it is vulnerable at best.
