504 BOTANICAL GAZETTE [DECEMBER 
FiLorma.—River Junction, Gadsden County, T. G. Harbison, April 25 
and September 21, 1914 (no. 1479), April 19 and June 25, 1917 (nos. 116, 119). 
From all other American lindens this species differs in the straight hairs on 
the lower side of the midribs and veins of the leaves, on the peduncle and 
branches of the inflorescence and on the branchlets, and similar to those of the 
European Tilia platyphyllos Scopoli. The number of these hairs varies on 
different individuals, and on some trees the branchlets become nearly glabrous 
by the middle of June, while on others the hairs are present for 2 or 3 years. 
They are longer and more abundant on the trees growing on the Savannah 
River at the Locks above Augusta than on trees from other localities, and do 
not entirely disappear until their third season. 
13. TILIA HETEROPHYLLA Ventenat.—Different plants have 
been referred to this species and it is still by no means clear what 
should be taken as the type. VENTENAT gives the locality for his 
tree as ‘‘la basse Caroline”? where it was discovered by MICHAUX 
and Fraser. ‘Basse Caroline” may mean the coast region or the 
whole state east of the mountains. There is no Tilia in the South 
Carolina coast region which at all agrees with VENTENAT’S descrip- 
tion and figure, but near Augusta and in Columbia County, Georgia, 
and in the neighborhood of Walhalla in Oconee County, South 
Carolina, on the eastern foothills of the Blue Ridge, a linden is 
common which in the shape of the leaves agrees better with those 
figured by VENTENAT than any I have seen. MIcHAvx in his 
journeys from Charleston to the high Carolina mountains went 
up the valley of the Savannah River and passed by Augusta and 
through Oconee County, South Carolina. VENTENAT describes 
the leaves of T. heterophylla as snow white on the lower surface. 
On the Georgia and Walhalla trees the tomentum on the lower 
surface of some of the leaves is white and on others, especially from 
upper branches, it is rusty brown, a peculiarity of this tree which is 
common in other parts of the country. WENTENAT describes the 
fruit of his tree as globose and 5-ribbed. The fruit which he figured, 
however, is ellipsoidal and shows no trace of ribs. If the Walhalla 
trees, as I believe, are to be considered typical of T. heterophylla 
Ventenat, that species may be described as follows: 
TILIA HETEROPHYLLA Ventenat, An. Hist. Nat. 2:63. 1800; 
Mém. Inst. Paris 4:16. ¢. 5.—Leaves ovate, obliquely truncate 
or rarely slightly cordate at base, gradually narrowed and acuminate
