ULMACEAE. — ULMUS 257 



Ulmus Wilsoniana, var. subhirsuta Schneider, n. var. 



A typo praecipue recedit ramis annotinis dense pilis griseo-brunneis obtectis fere 

 hiirsutis. 



CHINA. Southern Szech'uan: prope Hohsi versus Te-li-pu, May 7, 1914, 

 C. Schneider (No. 1113; frutex squarrosus, circiter 2-3 m. alius; with unripe fruits). 



I have seen this Elm only in this one locality, and the young fruits and leaves 

 agree well with those of the tjiae. The branchlets of the preceding year bear a very 

 dense grayish and brownish, almost hirsute, pubescence.

This European species does not occur in eastern Asia, where it is represented by 

 U. japonica Sargent, from which it differs by the characters given in the key on p. 

 249. It is mostly known as U . campestris or C7. j/iabra, but neither of these names can 

 be properly applied to it. Linnaeus's U. ca7npestris includes all the European Elms 

 and cannot be used for any one of them. By different authors mentioned above 

 the name U. nitens Moench has been adopted, but it is antedated by U. foliacea of 

 Gilibert, who gave a much better description of this tree than Moench did. In 

 the Oester. Bot. Zeitschr. I have pointed out that Gilibert's name undoubtedly refers 

 to our species.
