Prunus Nakaii differs from P. japonica gracillima Engleri in the much longer and 
more numerous hairs which cover the leaves beneath on the midrib and on the 
Veins and less densely on the whole surface. As the flowers are not yet known,

described as hairy but the hairs turned out to be particles of cotton sticking to the 
Tuits.
