Swartzia is a genus in the subfamily of Schmetterlingsblütler (Faboideae) within the family of the Leguminosae (Fabaceae). The approximately 150 Swartzia species are common in tropical areas of America , the Neotropic . The wood of at least some Swartzia species has a higher specific density than water and is particularly hard, which is why this species is often also called ironwood .


description

Swartzia species grow as trees. The leaves are pinnate. The flowers are zygomorphic and five-fold. There are legumes formed.

Systematics

The genus Swartzia was founded in 1791 by Schreb. in Genera Plantarum , 2, p. 518. Type species is Swartzia alata Willd. Homonyms are Swartzia Brid. , Journal für die Botany 1800 , (2), 1801 p. 289 and Swartzia J.F. Gmel. , Systema Naturae ... Editio decima tertia, aucta, reformata , 2, p 360. The genus Swartzia belongs to the tribe Swartzieae in the subfamily Faboideae within the family of the Fabaceae . Synonyms for Swartzia L. are: Possira Aubl. , Rittera Schreb. , Riveria Kunth , Tounatea Aubl.

The African species Swartzia fistuloides Harms Swartzia madagascariensis (Taub.) Desv. have been in the newly established genus Bobgunnia J.H. Kirkbr . & Wiersema , since then all the remaining Swartzia species have been native to the Neotropic . According to Magalhães 2006, the two species should be returned to the genus Swartzia .

The genus Swartzia is divided into two sections:

  • Section Possira ( Aubl. ) DC.
  • Section Swartzia :
    • Swartzia subsection
