1918] ; SARGENT—TILIA 435 
A variety of this tree which differs only in its glabrous corymbs and 
puberulous peduncles may be distinguished as 
TILIA FLORIDANA var. australis, n.var.—Tilia australis Small, 
Flora Southern U.S. 761. 1903; Tilia pubescens var. a Aitonii f. 
glabrata V. Engler, Monog. Tilia, 129 (in part). 1909. 
This variety I have seen only from Blount County, Alabama. 
Another linden of this group had best perhaps be considered as a variety 
of T. floridana, distinguished in the shape of its leaves and in their more 
prominent tufts of axillary hairs. I suggest for the name of this variety 
TILIA FLORIDANA var. oblongifolia, n.var.—Distinguished from 
the type by its ovate-oblong leaves with more conspicuous tufts 
of axillary hairs. Leaves thin, ovate-oblong, long-pointed and 
acuminate at apex, unsymmetrical and rounded on one side and 
broadly cuneate on the other, or very oblique and truncate at base, 
coarsely serrate with apiculate teeth, dark green, smooth and lus- 
trous on the upper surface, glaucescent or pale green on the lower 
surface, and furnished with usually large conspicuous tufts of 
axillary hairs, 8-ro cm. long and 6-8 cm. wide; petioles slender, 
glabrous, 3-4cm. in length. Flowers 5-6 mm. long, on slender, 
hoary tomentose pedicels, in wide, thin-branched, stellate-pubescent, 
mostly 15~-20-flowered corymbs; peduncle slender, glabrous, the 
free portion 2~2. 5 cm. long, the bract acuminate at base, rounded 
at apex, raised on a slender stem, 1.3-1.5 cm. wide, much longer 
than the peduncle; sepals acuminate, hoary tomentose on the 
outer surface, villose at the base and along the margins on the inner 
Surface; petals narrow, acuminate, nearly twice as long as the 
Sepals; staminodia narrow spathulate, rounded and erose at apex, 
about as long as the petals; stigma slightly villose at base. Fruit on 
slender pubescent pedicels, ellipsoidal, covered with pale brownish 
tomentum, 6-7 mm. long and 5-6 mm. wide. 
A tree with slender, glabrous, pale reddish brown branchlets, becoming 
dark red-brown in their second year. Winter buds obtuse, glabrous, 4-5 mm. 
in length. Flowers early in June. Fruit ripens at the end of July.
