Thalia geniculata, arrowroot,[2] fire-flag,[2] is a plant species widespread across tropical Africa and much of the Americas.
Thalia geniculata is native to a large region in Africa, from Senegal in the west to Sudan in the east, south to Zimbabwe and Angola. It is also considered native to Mexico, Central America, the West Indies, most of South America, as well as the southeastern United States (Puerto Rico, Florida, Louisiana, Alabama and southern Georgia).[1][3]
Ecology[edit]
The larvae of Stolidoptera tachasara, Xylophanes hannemanni and Sphenarches anisodactylus have been recorded feeding on Thalia geniculata.
Chemistry[edit]
Rosmarinic acid can be found in plants in the family Marantaceae such as Thalia geniculata.[4]

This species has the widest distribution known for any of the Marantaceae, occurring in both Africa and the Americas. Because of the marked lack of variation among the African populations, it is believed that its occurrence in west Africa was a historically recent, probably accidental, introduction (L. Andersson 1981b). The variation in pubescence and bract size within the American continent has been used as the basis for describing additional species or varieties (L. Andersson 1981b). Populations of Thalia geniculata with a striking red-purple coloration on the petiole, sheath, and pulvinus were described as T. geniculata f. rheumoides Shuey (A. G. Shuey 1975) . Such homogeneous populations are to be expected in a mainly selfing species.
