Brranching is an interface to many different sources of phylogenetic data (currently only from Phylomatic (, but more sources to come) that allows users to query for phylogenetic data using taxonomic names.

For brranching::phylomatic_names() function you should get an NCBI Entrez API key. NCBI Entrez doesn’t require that you use an API key, but you get higher rate limit with a key, from 3 to 10 requests per second, so do get one. Run taxize::use_entrez() or see for instructions.


Stable CRAN version


Or dev version



taxa <- c("Poa annua", "Phlox diffusa", "Helianthus annuus")
tree <- phylomatic(taxa=taxa, get = 'POST')
plot(tree, no.margin=TRUE)

You can pass in up to about 5000 names. We can use taxize to get a random set of plant species names.

spp <- names_list("species", 200)
out <- phylomatic(taxa = spp, get = "POST")
plot(out, show.tip.label = FALSE)
