Two new species of Esenbeckia (Rutaceae, Pilocarpinae) are described and illustrated. Esenbeckia decidua Pirani sp. nov. is probably endemic to deciduous forests of northern Minas Gerais, southeastern Brazil, and is distinct from other unifoliolate species in the genus because of its narrowly winged petiole, glabrous, not connate carpels that protrude beyond the annular disc, and its relatively elongated style. Esenbeckia kallunkiae Pirani sp. nov. is known from a few collections from Rondonia, the Brazilian Amazon and adjacent Bolivia. It is a species with trifoliolate, glabrous leaves, an elongate, narrowly paniculate inflorescence, relatively small flowers with cup‐shaped discs, short styles, and capsules densely muricate with hooked spines. New couplets to Kaastra's available key to species are provided.
