Topic: Gelsemiaceae


  
  Gelsemiaceae - Wikipedia, the free encyclopedia
Gelsemiaceae is a family of flowering plants, belonging to order Gentianales.
The two genera were formerly classified in family Loganiaceae; family Gelsemiaceae was described in 1994, and is distinguished by having no latex in the plants, and heterostylous flowers with yellow-white corollas, no latex or stipules, and superior ovaries.

Roughly 500 accessions were sampled from major tribes of the Strychnaceae, Loganiaceae, Gelsemiaceae, Gentianaceae, Apocynaceae s.l., and Rubiaceae.
Gelsemiaceae is supported as a distinct family and is unresolved along with Strychnaceae-tribe Antonieae and Rubiaceae.
Surprisingly, Gentianaceae is in the basalmost position; it is also the only family (except for tribes Antonieae and Spigelieae in the Strychnaceae) that lack alkaloids.

However, this is not entirely settled as Reveal (1997) and Thorne accept Gelsemiaceae, Loganiaceae and Strychnaceae, while Takhtajan removes Antoniaceae and Spigeliaceae from the latter.
Mitrasacme is similar to the tribe Hedyotideae (Rubiaceae) in a number of features and it may be this genus, with its superior ovary, might better fit in the Rubiaceae.
The close relationship of the Loganiaceae and Gelsemiaceae to the Rubiaceae is strongly supported by the available rbcL data.

She was hired as an Assistant Professor in both the Department of Plant Biology and Pathology and the Department of Ecology, Evolution and Natural Resources.
She is interested in the historical evolution and biodiversity of angiosperms, especially plants from the order Gentianales (Apocynaceae [dogbanes and milkweeds], Gelsemiaceae [Carolina jessamine], Gentianaceae [gentians], Loganiaceae [strychnine family], and Rubiaceae [coffee and madder family]).
As of spring 2002 she has developed graduate and undergraduate courses in plant systematics; and this spring teaches an Ethnobotany course.
