Western Szech'uan: Wa-shan, woods, alt. 2600 m., July and 

 October 1903 (Veitch Exped. No. 3285, type); same locality, alt. 

 2300-2600 m., October 1908 (No. 2326); Hung-ya Hsien, Wa-wu-shan, 

 woods, alt. 2300 m., September 14, 1908 (No. 2327). 



This very distinct species has the largest leaves of any of the Chinese Lindens 

 and is apparently most closely related to T. chinensis Maximowicz, which has 

 smaller leaves clothed on the under side with a pale gray felt, very much smaller, 

 densely pubescent bracts, and smaller and more globose fruit. This new species 

 has a very local distribution and is not common.
