Diagnosis:— Serjania perulacea var. krapovickasii is a woody vine distinguished from S. perulacea var. perulacea by the absence of indumenta, leaflets subchartaceous, smaller and with margin dentate-serrate with acute teeth.

Woody vine, glabrous. Leaves imparipinnate, 3–jugate, the lower jugae 2 jugate, 3–5–foliolate; leaflets subchartaceous; terminal leaflet narrowly ovate, 2.2–12 × 0.4–7.0 cm; apex acute although less frequent obtuse-mucronate; base decurrent in terminal leaflet or acute in the proximal and distal leaflets; margin dentate-serrate with 7–10 conspicuous acute teeth.

Distribution:— Serjania perulacea var. krapovickasii is known in the Chuquisaca, Santa Cruz and Tarija departments, in Bolivia; Goiás, Minas Gerais, Mato Grosso, Mato Grosso do Sul and São Paulo states, in Brazil; and Alto Paraguay, Amambay, Boquerón, Capital, Cordillera, Ñeembucú, Paraguarí, Presidente Hayes and San Pedro departments, in Paraguay.

Etymology: —This variety is named in honor of Dr Antonio Krapovickas who was the Director of the Instituto de Botánica del Nordeste between 1977 and 1991. Dr Krapovickas constantly supported our scientific work and always provided wise advice on taxonomy, nomenclature and life in general.
