Ribes ambiguum is
a small deciduous shrub inhabiting the tops of old broad-leaved
trees in mountainous regions, hanging down to 50-100cm in length.
Unless the tree has fallen, it is impossible to see one. Leaves are
of alternate phyllotaxis; 2-5 leaves gather on each short branch
tip. Their blades measure 3-5cm in diameter, are in a reniform-orbicular
shape, and are palmately cleft in 3-5 lobes, the margins having
serrations. Flower buds, 1 or 2 in number, emerge from the short
branch tips, and small light green-white blooms bloom. The fruit is
oval with needle-like glandular hairs - it remains green even if
ripened. Bloom time: April-May.
