D'après Vorontsova (
2022): "Boivin’s Nosy Be collections of
Brachiaria umbellata are
numerous and it is not possible to verify which ones may have originally constituted a single gathering, or which exact sheet Steudel (1854) may have been referring to as “Boivin legit in Ins. Nossibé”, not citing a collection number. The more comprehensive and fully labelled sheets of these collections bear the number 1962 and a collection date of June 1847, while others only bear the printed date range 1847 – 1852. The lectotype selected here is the best quality and most extensively annotated sheet of Boivin’s herbarium."
