VARIETY DISTINGUISHED IN CULTIVATION 



Acer rubrum sanguineum (Spach) Pax. 



19 Acer stenocarpum Britton and Shafer (North Am. Trees, 647, fig. 598, 1908) was described as a distinct 

 species, which is represented by small trees growing in flinty soil at Alenton, Missouri. The unusual 

 soil conditions under which these trees are growing may possibly account for the narrow-winged samarae, 

 relied upon chiefly to distinguish this plant from Acer rubrum Linnasus; in other respects it appears to be 

 a form only of the Red Maple. The flowers of Acer rubrum Linnaeus are some times brilliant red and some 

 times yellowish, and from the latter characteristic Acer rubrum var. pallidiflorum Pai was described.
