Cedrela fissilis is a species of tree in the family Meliaceae. It is native to Central and South America, where it is distributed from Costa Rica to Argentina.[2] Its common names include Argentine cedar,[2] cedro batata, cedro blanco, "Acaju-catinga" (its Global Trees entry) and cedro colorado.[1]

Once a common lowland forest tree, this species has been overexploited for timber and is now considered to be endangered. A few populations are stable, but many have been reduced, fragmented, and extirpated. The wood is often sold in batches with Cuban cedar (Cedrela odorata).[1]

Taxonomy

Original Description

Cedrela fissilis was first described by José Mariano da Conceição Vellozo in Florae Fluminensis (1829). The original protologue reads (translated):[3]

C. fissilis. Flowers in racemose, compound inflorescences; leaves hairy beneath. (Tab. 68.a T. 2) Observations. Both species yield timber of the highest quality for construction. It is said that on the Island of São Sebastião there stands a Cedrela of such enormous size that from it a boat (scapha) could be made measuring 11 palms in width. For this to be true, the trunk would necessarily have a circumference of 44 palms.

Taxonomic history

Cedrela brasiliensis was first described by Antoine Laurent de Jussieu in Flora Brasiliensis Meridionalis (1829), based on material collected in Minas Gerais, Brazil.[5] Jussieu distinguished a southern variant, var. australis, from specimens near Montevideo, noting denser pubescence on the branches, petioles, peduncles, and petals, and questioned whether this form might represent a distinct species. Both C. brasiliensis and its variety australis are now regarded as synonyms of C. fissilis.[6][7]
