Renner: Placing Biebersteiniaceae, a herbaceous clade of Sapindales, in a temporal and geographic context in Plant Systematics and Evolution , Volume 266, Issue 3-4, 2007, p. 233 –252 it forms its own family Biebersteiniaceae Endl. within the order Sapindales .
There are only four or five species in the genus Biebersteinia :
- Biebersteinia heterostemon Maxim. : It thrives at altitudes between 1000 and 3800 meters in the Chinese provinces of Gansu, Ningxia, Qinghai, Sichuan and Xizang.

(Syn .: Biebersteinia rucheri Walp. , Biebersteinia ambigua Jaub. & Spach , Biebersteinia aucheri Jaub. & Spach , Biebersteinia brachypetala Jaub. & Spach , Biebersteinia leiosepala Jaub. & Spach , Biebersteinia multifida var.
