A very curious variet}', flaunting the blossom before a few years after 

 the seedling. It differs from the type (a. spontanea Maxim.) by the shrubby 

 habit, subirregular serration of leaves, elongate and sometimes foliiferous 

 peduncle, and more densely flowered branchlets. The mother tree was 

 found at a village called Ogawa in the neighborhood of Sakawa.
