face, densely pubescent early in the season, later becoming nearly glabrous on the lower 

 surface, 3'-6' long and f'-lj' wide, longer or shorter than the peduncle and decurrent 

 to its base or to within 1|' of its base; sepals ovate, acute, pale pubescent on the outer 

 surface, covered on the inner surface with white hairs longer and more abundant near the 

 base; petals lanceolate, acuminate, a third longer than the sepals; staminodia linear-lance- 

 olate, acuminate; style hoary-tomentose at base. Fruit ellipsoid, covered with rusty brown 

 tomentum, 5' long and |' broad. 



A small tree w r ith slender branchlets thickly covered during their first season with close 

 pale pubescence, and pale and puberulous or glabrous in their second year; on vigorous 

 terminal branchlets often with thicker, light rusty brown pubescence. Winter-buds ovoid, 

 obtusely pointed, thickly covered with pale pubescence, |' long. 



Distribution. Texas, Brazos and Cherokee Counties, on Spring Creek near Boerne, 

 Kendall County, and on the rocky banks of the Guadalupe River at Kerrville, Kerr 

 County. 



11. Tilia phanera Sarg. 



Leaves semiorbicular to broad-ovate, deeply and usually symmetrically cordate at base, 

 abruptly short-pointed at apex, finely dentate with straight or incurved apiculate teeth, 

 glabrous above when they unfold with the exception of a few hairs on the midrib 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 or scabrate (var. scabrida Sarg.) on the lower 

 surface, 2'-4' wide and usually rather broader than long, with a slender midrib and primary 

 veins pubescent on the lower side, and small axillary clusters of rusty brown hairs; petioles 

 slender, coated when they first appear with hoary tomentum, glabrous or slightly pubescent 

 in the autumn, I'-l^' in length. Flowers opening the middle of June, \' long, on tomen- 

 tose pedicels, in compact villose mostly 16-20-flowered cymes; peduncle villose, the free 

 portion \\' in length, its bract obovate, cuneate at base, broad and rounded at apex, fleccose- 

 pubescent on the lower surface, nearly glabrous on the upper surface, 3'-3%' long and

?'-!' wide, longer than the peduncle and decurrent to its base or to within \' of its base; se- 

 pals acuminate, pale pubescent on the outer surface, villose on the margins and furnished 

 at base on the inner surface with a tuft of long white hairs, broader and shorter than the 

 lanceolate acuminate petals; staminodia oblong-obovate, rounded at apex, style glabrous 

 except at the base. Fruit ripening the end of September, ellipsoid, covered with rusty 

 tomentum, i'-f long and \' wide, on a stout, densely floccose-pubescent pedicel.
