Subcymose calunga (Simaba subcymosa)
Simaba subcymosa: Botanical Overview, Distribution, and Facts
The Atlantic Forest regions of southeastern Brazil, particularly within Minas Gerais and Rio de Janeiro, serve as the native habitat for Simaba subcymosa.
This wild woody plant belongs to the Simaroubaceae family and was first described by the botanists Auguste de Saint-Hilaire and Louis René Tulasne. It forms part of the rich and endangered flora of the Brazilian Atlantic forest zone.

Morphology
The botanical characteristics of this species reflect its adaptation to the seasonal forests of southeastern Brazil:
- Inflorescence: Features a subcymose arrangement, where flowers are grouped in cluster-like structures that resemble cymes.
- Growth Form: Grows as a woody shrub or small tree within the forest understory.
- Leaves: Possesses alternate, pinnately compound leaves with a coriaceous texture.
- Flowers: Small, pentamerous flowers with inconspicuous petals and sepals, typical of the family.
Interesting facts
This species was co-described by the prominent French botanist Auguste de Saint-Hilaire, who extensively explored the flora of Brazil in the early 19th century. The specific epithet subcymosa describes its flower clusters, which form a modified, nearly flat-topped cyme structure. Growing in the highly threatened Atlantic Forest, it is part of one of the world's most critical biodiversity hotspots.
