'Frangula azorica' from the website Trees and Shrubs Online (treesandshrubsonline.
This species, a native of Madeira and the Azores, has leaves up to 5 in. long, 3 in. wide, with ten to sixteen pairs of parallel veins and a stalk 1{1/4} in. long. Akin to R. frangula, it differs not only in its larger, more numerously veined leaves, but also in haying a downy flower-stalk and calyx, the former up to {5/8} in. long. Fruits nearly {1/2} in. across, red, then black. Introduced in 1778; now very rare, but worth growing for its handsome foliage. Bot. Mag., t. 2663.
