Discussion
Genus 1, species 2 (1 in the flora).
Koeberlinia has been included in the traditional Capparaceae by some authors, including A. Cronquist (1981). Recent molecular studies support its removal from Capparaceae and a relationship with Bataceae and Salvadoraceae (P. F. Stevens, www.mobot.org/MOBOT/research/APweb).
