Near Acer Davidi FRANCHET, but differs from it in having the leaves with 

 three lobes, two of which are very obscure. The present plant is also very 

 like A. laxiflorum. There is at Kew a specimen exactly like this, labelled 

 " Acer off Hooker!, China No. 218." It is very like A. Hooker!, but quite 

 separable from it.
