Ribes sanchezii

Ribes sanchezii is a species of currant, named after Peruvian botanist Isidoro Sánchez Vega of Cajamarca. This species of "Ribes" is distinct form both "R. andicola" and "R. colandina" because of its ovate to elliptical leaves with a very poorly developed lateral lobe and its aberrant indument. The two latter species have leaves with pubescence on both the adaxial and abaxial surface and the adaxial leaf surface is matt green, whereas "R. sanchezii" has a shiny dark green upper leaf surface and pubescence abaxially restricted to the primary and secondary veins. "Ribes sanchezii" also has strongly resupinate fruits, whereas the fruits of "R. andicola" and "R. colandina" are pendulous.

It is a dioecious shrub, approximately tall; its shoots and adaxial leaf surfaces being sparsely pubescent to glabrous. Its petioles are moderately pubescent; its trichomes approximately long. Its petiole is long and 1mm wide. Its inflorescences are terminal on short lateral shoots (brachyblasts); its racemes are pendent, while the peduncle is and densely pubescent with numerous simple hairs that are 1 mm long. Its pedicels are approximately 1mm long and apart in open flowers. The flowers are narrowly cyathiform, while the calyx and corolla are a dark red colour, x 5mm and covered with simple hairs long. The fruit strongly resupinate.
Distribution.
La Libertad. It replaces widespread "R. colandina" on the eastern slopes of the Cordillera Oriental and forms dense stands at the upper limit of the cloud forest at the Abra CallaCalla, where it is one of the most abundant shrub species.
