232 BOTANICAL GAZETTE [march 



Leaves remaining on the branches until spring without change 

 of color, elliptic to oval, oblong-obovate or rarely lanceolate, 

 with puberulous, pubescent, or tomentose petioles and varying in 

 width from 2.5 to 9.5 cm., trees with the broadest leaves being 

 confined to western Louisiana and eastern Texas. This southern 

 variety of M. virginiana is a tree often 20-30 m. high with a tall 

 trunk occasionally i m. in diameter, covered with pale smooth bark 

 and short small branches forming a narrow round-topped head, 

 and branchlets more or less thickly covered during their first season 

 with white silky pubescence, usually gradually disappearing in their 

 second year; in southern Florida often much smaller, and on the 

 Everglade Keys, where it is "very common, a shrubby tree up to 

 3 m. high" {E. A. Bessey). 



Swamps in the neighborhood of Wihnington, North Carolina, is the most 

 northern station from which I have seen specimens of this tree; it is common 

 in the coast region of South Carolina and Georgia and in all parts of Florida, 

 and the only form of M. virginiana in the other Gulf states, where it occurs 

 as far west as the valley of the Nueces River in Texas (San Augustine Coxmty) , 

 but is much less common west of the Mississippi River than it is farther east. 

 Although it crosses the Florida peninsula this Magnolia is most abundant in 

 the coast region. It ranges inland, however, to Cuthbert, Randolph County, 

 in western Georgia, to Tuskegee and Selma, Alabama, and to Tishomingo 

 County in the extreme northeastern corner of Mississippi, and to Winn and 

 Natchitoches parishes in western Louisiana. 



Magnolia acuminata var. ludoviciana, n. var. — Differing from 

 the type in its broadly obovate, oval, or ovate leaves abruptly 

 short-pointed at apex and rounded or cuneate at base, and in its 

 much larger flowers. Leaves hoary tomentose below and slightly 

 pubescent above when they unfold, becoming when the flowers open 

 glabrous and yellow-green on the upper surface and pubescent on 

 the lower surface with short pale hairs, 15-18 cm. long and 9-13 cm. 

 wide; petioles puberulous, 2.5-4 cm. in length. Flowers 8-10 cm. 

 long, the outer petals up to 4 cm. in width. 



A large tree.
