Cerasus glandulosa Loiseleur, Nouv. Duhamel, V. 33 (1825). 
For a century this species has been always confused with P.japonica Thunberg, 
but it is very distinct and not connected with the latter by any intermediate forms. 
The opinion that transitions between these species existed arose from the fact that 
in herbaria admixtures of P. biflora Koehne and even of Spiraea prunifolia Siebold 
& Zuccarini often occur without being recognized, and the characteristic shape of 
the leaves has thus been obscured.
