Commiphora holtziana subsp. microphylla J.B.Gillett
Small-leaved Holtz's Commiphora
Subspecies of Commiphora holtziana described by J.B. Gillett, differentiated from the typical species by its notably smaller leaves (microphylla = small leaf). Inhabits arid zones of East Africa, with a distribution range that partially overlaps with the typical species but extends into more xeric habitats. Shares the succulent bark and spiny habit of the genus.

"Subspecies of C. holtziana (RN-CMPH-00006) described by J.B. Gillett; distinguished mainly by the markedly smaller leaves. Leaf reduction is a frequent convergent adaptation in Commiphora of hyper-arid habitats. Molecular revision pending to confirm its subspecific status."
