Leaves ovate, abruptly narrowed and acuminate at apex, usually oblique and unsymmetrically cordate or truncate or occasionally symmetrical and cordate at base, crenately serrate, the teeth tipped with minute glands, covered when they unfold with pale caducous tomentum, and at maturity dark green and lustrous above, glaucescent below, glabrous with the exception of minute axillary tufts of rusty hairs, mostly 3½′—5½′ long and 2¾′—3′ wide; petioles slender, glabrous, about 1¼′ in length. Flowers opening the middle of June, ⅓′ long, on hoary-tomentose pedicels, in compact mostly 10—18-flowered tomentose cymes; peduncle glabrous, the free portion 1′—1½′ in length, its bract oblong-obovate, cuneate at base, rounded at apex, glabrous, 3′—5′ long, usually about ⅘′ wide, decurrent nearly to the base of the peduncle; sepals acute, hoary-tomentose on the outer surface, coated with pale tomentum mixed with long white hairs on the inner surface; petals narrow-acuminate; staminodia oblong-obovate, notched at apex. Fruit ripening from the middle to the end of August, ellipsoid, conspicuously apiculate at apex, rusty-tomentose, ⅓′—⅖′ long and ¼′—⅓′ in diameter.
A tree, 25°—30°, rarely 60° high, with a trunk 10′—12′ rarely 18′—20′ in diameter, and slender glabrous red-brown branchlets. Winter-buds ovoid, acute, dark dull red, glabrous, ⅙′—⅕′ long.
Distribution. Near Albany, Dougherty County, Georgia, to central Florida (Levy, Columbia, Alachua, Putnam, Seminole and Orange Counties).
6. [Tilia floridana] Ashe.
Leaves broad-ovate, acuminate or abruptly acuminate at apex, cordate or obliquely truncate at base and coarsely serrate with apiculate teeth, tinged with red and tomentose below when they unfold, fully grown and glabrous or nearly glabrous when the flowers open late in May or in early June, and at maturity thin, glabrous, dark yellow-green on the upper surface, pale or rarely covered below with a silvery white bloom (var. hypoleuca Sarg.), 3½′—5′ long and 2½′—3½′ wide, with a slender midrib and primary veins; in the east usually without axillary tufts, often present and sometimes conspicuous westward; petioles slender, glabrous, ¾′—1′ in length. Flowers opening in early summer ⅕′—¼′ long, on hoary-tomentose rarely puberulous (var. australis Sarg.) pedicels, in few-flowered rather compact pubescent corymbs; peduncle pubescent, the free portion 1½′—2½′ in length, its bract oblong-obovate to oblong, rounded at apex, often falcate, glabrous, 3′—6′ long, ½′—¾′ wide, decurrent nearly to the base of the peduncle; sepals narrow, ovate, acuminate, hoary-tomentose on the outer surface, sparingly villose on the inner surface, two-thirds as long as the lanceolate petals; staminodia oblong-obovate, acute, nearly as long as the petals; style glabrous. Fruit ripening in August and September, subglobose to ellipsoid, rusty-tomentose, ½′ in diameter.
A tree, 40°—50° high, with a trunk 12′—15′ in diameter, and slender glabrous red-brown or yellow branchlets. Winter-buds obtuse, dark red-brown, glabrous, about ⅙′ long.
Distribution. North Carolina (Polk County) to western Florida and westward through northern and central Alabama, central Mississippi, northern and western Louisiana, eastern and over the Edwards Plateau to Kerr, Bandera and Uvalde Counties, Texas, and through southern and western Arkansas to eastern Oklahoma, Missouri and eastern Kentucky; in northeastern Mexico; the var. australis in Blount County, Alabama. A variety (var. oblongifolia Sarg.) with narrower more elongated leaves with more prominent tufts of axillary hairs occurs in Putnam, Leon and Gadsden Counties, Florida, on the bluffs of the Alabama River near Berlin, Dallas County, Alabama, in Hinds, Rankin and Adams Counties, Mississippi, in West Feliciana, Iberia (Avery Island) and Natchitoches Parishes, Louisiana, in Hempstead and Salina Counties, Arkansas, and in Harris, Anderson and Livingston Counties, Texas.
