1918] SARGENT—TILIA 427 
the axillary tufts cannot always be depended on, for occasional trees have been 
found in Louisiana and Alabama on which some of the leaves are furnished with 
these tufts (Louisiana, near Alexandria, Rapides Parish, R. S. Cocks, June 
1905; Wakefield, West Feliciana Parish, R. S. Cocks, June 1905. Alabama, 
near Selma, Dallas County, R. S. Cocks, June and July ror4, June 2, July 12, 
1915 [no. 784], April 20, July 25, 1916 [nos. 822, 960]). 
A form of this tree with leaves more or less pale on the lower surface may 
be distinguished as 
TILIA NUDA var. glaucescens, n.var.—Differing from the type 
in the glaucous lower surface of the leaves. 
ALABAMA.—Bluffs of the Alabama River, Berlin, Dallas County, R. S. 
Cocks, June 11, July 20, 1915 (no. 786 type). 
OUISIANA.—Lake Charles, Calcasieu Parish, R. S. Cocks, May 21, 1915 
(no. 2534); Natchitoches, Natchitoches Parish, E. J. Palmer, May 10, June o, 
1915 (nos. 7569, 7923), June 9, 1915 (no. 7923). 
OKLAHOMA.—Page, Le Flore County, E. J. Palmer, July 27, 1917 
(no. 12638). 
TEXxas.—Marshall, Harrison County, E. J. Palmer, June 8, 1915 (nos. 7909, 
7912); San Augustine, San Augustine County, E. J. Palmer, June 5, 1915 
(no. 7880). 
Like the green-leaved type, the trees of this variety differ in the size of the 
leaves, in the pedunculate bract which on Palmer’s no. 7923 ftom Natchitoches 
is 8 cm. wide, while on his no. 7909 from Marshall it is only 3.5 cm. wide. The 
number of flowers’ in a corymb is equally variable. The tomentum on the fruit 
of Cock’s no. 786 from Sardis, which is the only fruit of the variety which I have 
seen, is paler than that on the fruit of the green-leaved form. 
TILIA NuDA var. brevipedunculata, n.var.—Differing from the 
type in the serration of its smaller leaves glaucescent below, in the 
shorter free portion of the peduncles of the inflorescence, and in its 
broader bract. Leaves ovate, gradually or abruptly narrowed and 
acuminate at apex, obliquely and unsymmetrically cordate or 
rounded at base, finely crenately serrate with gland-tipped teeth, 
smooth and dark yellow-green on the upper surface, pale yellow- 
green and glaucescent on the lower surface, glabrous, 7-8 cm. long 
and 5 or 6 cm. wide; petioles slender, glabrous, 2-2.5 cm. in length. 
Flowers 5 or 6 mm. long, on pubescent pedicels, in compact, mostly 
10-20-flowered, sparingly pubescent corymbs; peduncle sparingly 
pubescent, the free portion only about 1.5 cm. in length, the bract 
broad and rounded or unsymmetrically cuneate at base, rounded
