1910 (No. 4016). 
This species resembles in its pubescence P. pulchella Koehne, but P. pulchella 
has longer racemes and the glands of the teeth of the leaf are very small. Prunus 
pleiocerasus Koehne and P. conadenia Koehne differ in being glabrous and in their 
longer racemes with more flowers. In its short racemes P. macradenia Koehne, 
somewhat approaches P. tatsienensis Batalin, which differs, however, in the 2(-4)- 
flowered umbels and in being glabrous.
