riety (var. brevipedunculata Sarg.), differs from the type in the Jess coarsely serrate smaller 

 leaves glaucescent below, in the shorter free portion of the peduncle of the inflorescence and 

 its broader bract. A tree 25-30 high, with slender glabrous dark red-brown branchlets. 



3. Tilia venulosa Sarg. 



Leaves broad-ovate, abruptly acuminate at apex, cordate or unsymmetrically cordate 

 or obliquely truncate or cordate at base, coarsely serrate with gland-tipped teeth pointing 

 forward, covered when they unfold with pale tomentum, soon becoming pubescent, and 

 glabrous before the flowers open, dark yellow-green on the upper surface, paler on the lower 

 surface, 4'-4f ' long and broad, with a prominent pale yellow midrib slightly villose on the 

 upper side near the base, and 9 or 10 pairs of remote primary veins without axillary tufts 

 and connected by conspicuous cross veinlets; petioles stout, glabrous, If '--2' in length. 

 Flowers opening early in Julv, ' long, on slightly pubescent pedicels, in broad slender- 

 branched nearly glabrous cymes; peduncle stout, glabrous, red, the free portion I'-l?' in 

 length, its bract oblong to slightly obovate, gradually narrowed and rounded at base, 

 rounded at apex, glabrous on the upper surface, pubescent below on the midrib and veins, 

 3|'-6' long and \\'-\%' wide, longer than the peduncle and decurrent nearly to its base or 

 to within I'-l?' of its base; sepals ovate, acute, pale pubescent on the outer surface, 

 villose and furnished at base on the inner surface with a tuft of long white hairs, a third 

 shorter than the lanceolate acuminate petals; staminodia oblong-obovate, rounded at 

 apex, about as long as the sepals; stigma slightly villose at base. Fruit ripening the end 

 of September, subglobose, '-$' in diameter, covered with loose light brown pubescence. 



A tree, 60-75 high, with stout red glabrous branchlets. Winter-buds ovoid, cylindric, 

 obtusely pointed, dark red, ?' |' in length.
