relates to Georgia and Florida, not Hooker and Arnott). 1903. — 

 This variety, which was based on trees cultivated in Europe, is dis- 

 tinguished by the close pale pubescence which covers the lower 

 surface of the leaves during the season. The leaves are 5-lobed, 

 cordate or rarely rounded at base, and the petioles are glabrous 

 or slightly pubescent early in the season. The branchlets are 

 usually glabrous and the winter-buds are pubescent. 



I have seen specimens of this form of the red maple from Biltmore, North 

 Carolina (Herb. Bilt. no. ii6b), from the neighborhood of Augusta, Georgia, 

 from the top of Flagstaff Mountain, Barclay, Alabama, Panther Burn, Sharkey 

 County, Mississippi, Larissa, Cherokee County, Texas (B. F. Bush, May i, 

 1909, no. 5579), near Page, Leflore County, Oklahoma (G. W. Stevens, no. 2617), 

 and swamps near Little Rock, Pulaski County, Arkansas. 



A specimen of this variety with pubescent branchlets and winter-buds, 

 and slightly pubescent petioles, collected by J. K. Small at the Altamaha River 

 Swamp, Liberty County, Georgia, in June 1895, and specimens collected by 

 Mohr in April 1895 at Mount Vernon, Mobile County, Alabama, with broadly 

 ovate, 3-5-lobed, slightly cordate leaves with pubescent petioles, fruit only 

 3 . 5 cm. long, and glabrous branchlets, serve to connect the variety tomentosum 

 with 



Acer rubrum var. Drummondii Sarg. — The leaves of this tree 

 are often broader than long, cordate at base, usually 5-lobed, with 

 stouter midribs and veins than those of the other forms of A. 

 ruhrum. Until nearly fully grown the leaves are covered on the 

 upper surface with scattered pale hairs and are clothed below with 

 thick snow white tomentum which is more or less persistent during 

 the season; the petioles are stouter than those of the other forms 

 of the red maple, and are covered during the season with thick 

 white tomentum similar to that on the under surface of the leaves. 

 This gradually disappears and the petioles often become nearly 

 glabrous in the autumn. The fruit, which ripens in early spring 

 before or with the unfolding leaves, varies from 5 to 6 cm. in length. 



This maple, which is a smaU tree usually not more than 10-12 m. high, 

 inhabits deep river swamps often inundated through the year. It is dis- 

 tributed from the valley of the Hastchatchee River, Forrest County, southern 

 Mississippi, through Louisiana to the valley of the Neches River, Texas 

 (Beaumont and Concord). It is not rare in southern and eastern Arkansas, 

 southeastern Missouri, and occurs in northwestern Mississippi (Morehead,
