TILIACEAE. — TILIA 367 



the under surface of its leaves this species resembles the European T. tomentosa 

 Moench. 



Both Szyszylowicz and V. Engler worked with little material, otherwise 

 they would not have attempted to make two species out of such a homogeneous 

 and clearly defined species as T. Oliveri. 



In No. 634 the shoots and winter-buds are sUghtly pubescent and the fruit is 

 less tuberculate than is usual in the species.

Western Hupeh : Fang Hsien, woods, alt. 1600-2300 m., May 19, 

 July and November 1907 (No. 2338, type, 597"; tree 6 m. tall). 



This variety is distinguished by the gray not white under surface of its leaves 

 and the pubescence is more loosely tomentose; the leaves are distinctly serrate 

 with broad, short teeth. In No. 597*=, which consists of a shoot with partly grown 

 leaves, the branchlets are pendulous and the under side of the leaves very sparsely 

 pubescent.

This very distinct species is not common, but it grows to a greater size than any 

 of the other species from central or western China. In habit it resembles the 

 European T. tomentosa Moench, and the bark is light gray, firm and fissured. As 

 the leaves unfold in the spring they are covered with a nearly white, loose to- 

 mentum and the trees in this stage are conspicuous from a distance As the leaves 

 develop this tomentum more or less completely disappears from both surfaces and 

 what remains becomes darker in color and on dried specimens fulvous-gray. The 

 young shoots in early spring have a similar tomentum to that of the leaves, but in
