Maple, Drummond's. Acer rubrum, var. Drummon- 

 dii. A southern variety of the Eed Maple found in the 

 river-swamps, from southern Georgia to Florida, Mis- 

 souri, and Texas. It is a large tree with larger, thicker 

 leaves than those of the typical Eed Maple, and they 

 are permanently white-fine-hairy beneath at least along 

 the veins; the twigs and the leaf-stems are also fine- 

 hairy. The large-winged seed-vessels are smooth, with 

 the wings at a more or less narrow angle; they turn a 

 bright red, and are ripe in March or April. 



Maple, Trident-leaved. Acer rubrum, var. tridens. 

 Leaves small, from 2 to 3^ inches in length, with three 

 short lobes, the middle one broadly triangular; there 

 are few, if any, teeth below the lobes. This variety is 

 found locally from Massachusetts south, and westward 

 to Missouri and Texas.

 age length being about 2^ inches, mostly obovate with 

 3-7 lobes (commonly with 5), olive-green and smooth 

 above, grayish-white and fine-woolly beneath, the stems 

 short and the lobes somewhat triangulate and bristle- 

 tipped. Acorn scarcely i inch long, the cup deep saucer- 

 shaped. Bark brownish gray and nearly smooth. This 

 species is common in sand}' barrens and rocky soil on or 

 near the coast from Maine to Delaware, west to Ohio,
