Origin of the genus could be Africa. Or Asia. Or the Arabian Peninsula. So that narrows it down.

All things tropical forages
Great article on improved tropical pastures by Dan Charles on NPR’s The Salt yesterday. Here’s the money quote:
According to Michael Peters, who leads CIAT’s research on tropical grazing, pastures made up of these grasses can support three times more cattle, compared to typical tropical pastures today. The animals also gain weight twice as quickly. It translates into a six-fold increase in production per acre, and a dramatic cut in greenhouse emissions.
“These grasses” are Brachiaria species, but of course there’s much more than just those in CIAT’s forages genebank. And then there’s ILRI’s forages genebank too. And a global strategy to rule them all. And a newsletter to subscribe to if you want to keep up to date.
