It was first described as Nymphaea hirta Kurz ex Teijsm. & Binn. by Wilhelm Sulpiz Kurz but validly published by Johannes Elias Teijsmann and Simon Binnendijk in 1864. Later, it was transferred to the genus Barclaya Wall. as Barclaya hirta (Kurz ex Teijsm. & Binn.) Miq. by Friedrich Anton Wilhelm Miquel in 1870.[4][5][1][2] The type specimen was collected by Johannes Elias Teijsmann in Sumatra, Indonesia.[2]
Etymology
The specific epithet hirta, from the Latin hirtus, means hairy.[6]
