1918] SARGENT—TILIA 501 
near Boerne, Kendall County, E. J. Palmer, April 7 and September 29, 1917 
(nos. 11485, 12899); along the southwest bank of the Guadalupe River on 
the rocky talus in a canyon at the foot of a limestone bluff at Kerrville, Kerr 
County, E. J. Palmer, October 2, 1916 (nos. 10887, 10888 type for fruit), 
April 8 and June 9, 1917 (nos. 11495, 11501, 11502, 12212, 12213 type for 
flowers, 12214). 
I have not seen leaves and coepens bracts with lateral lobes on any 
other American linden. 
TILIA TEXANA var. grosseserrata, n. var.—Differing from the 
type in the coarse serration of the leaves, in the absence of lateral 
lobes on the leaves and on the bracts of the peduncles, and in the 
constantly pale, never rusty pubescence of the branchlets and 
winter-buds. 
A small tree with several stems 7~9 m. high, the bark dark gray and rough 
near the ground and smooth and pale above, ih rocky soil at the foot of a lime- 
stone bluff by a small stream forming the head of the Sabinal River, near 
Utopia, Uvalde County, Texas, E. J. Palmer, June 17, 1916 (no. 10227 type), 
April 10 and October 6, 1917 (nos. 11522, 12937). 
At the end of their first winter the branchlets of this tree are pale pubescent, 
puberulous or nearly glabrous, and the winter-buds are reddish or pale brown 
and glabrous. This linden is interesting as the most western representative 
of the genus in the United States. 
11. Tilia phanera, n. sp.—Leaves semiorbicular to broadly 
ovate, deeply and usually symmetrically cordate at base, abruptly 
short-pointed at apex, finely dentate with straight or incurved 
apiculate teeth; when they unfold glabrous above with the excep- 
tion of a few Sindee on the midribs and veins, and thickly coated 
below \with hoary tomentum, and at maturity thin, blue-green, 
smooth and lustrous on the upper surface, paler and often brownish 
and coated with a floccose easily detached pubescence of fascicled 
hairs on the lower surface, 5—9 cm. wide and usually rather broader 
than long, with slender midribs and primary veins pubescent on the 
lower: surface, and small axillary clusters of rusty brown hairs; 
petioles slender, coated when they first appear with hoary tomen- 
tum, glabrous or slightly pubescent in the autumn, 2.5-4 cm. in 
length. Flowers 5—6 mm. long, on tomentose pedicels in compact, 
villose, mostly 16-20-flowered corymbs; peduncle villose, the free 
portion 1.2-1.5 cm. in length, the bract longer than the peduncle,
