It was formerly placed in the genus Caesalpinia but phylogenetic studies identified the group to be polyphyletic, leading the placement of Caesalpinia mimosoides in a new genus, Hultholia in the tribe Caesalpinieae.

[1][4] Its distribution includes: Bangladesh, Yunnan in China, India, Laos, Myanmar, Thailand, and Vietnam.

[1] This species is distinct and can be separated from Caesalpinia by the glandular spots covering the stem, calyx, and fruits.

The genus name commemorates the Cambodian taxonomist Salvamony Hul Thol.

[5] It is a food plant for the caterpillars of Eurema blanda.
