the branclilcts sparingly pilose; Meyer's specimen approaches our variety 

 also in tlie red-browTi color of the branclilcts and in the very short petioles. 

 JJlmus pumila has not before been recorded from Yminan, but I suspect 

 that the Ehu enumerated by Leveille in his Cat. PL Yun-Nan, p. 276 (1917) 

 as TJ. parvifolia Jacquin is this new variety.

The material in the Arboretum hcrbariinn from China proper, formerly 

 referred to Ztikova ^errata (Z. acuminata Planch.) has been found to belong 

 to Zelkova sinica Schneider (in Sargent, PL Wilson, iii. 286 [191G]). We 

 therefore concluded that Z. serrata is restricted to Japan and Korea. The 

 specimen cited above, however, which is undoubtedly true Z. serrata, as it 

 agrees exactly with specimens from Japan proves that Z. serrata extends 

 far into southern China; Wukang being situated in the southwestern part

These specimens agree in all characters exactly with typical M. mongolica 

 except in the pubescence of the leaves and of the peduncles which are gla- 

 brous or nearly glabrous in the type. 



BERBERIDACEAE 



Mahonia repens f. subcordata, f. nov, 



A typo recedit foliolis 5-7, rarius 9, approximatis late ovatis basi sub- 

 cordatis, dentibus paucis remotis fere ad mucroncm reductis intcrdum 

 fere integris. 



Cultivated at Highland Park, Rochester, N.Y. (Type specimen coll. May 10-11, 

 1913. by /?. E, Horsey & /. Bishop, preserved in the Arnold Arboretum Herb.) 



This is a rather distinct looking form characterized by the 5-9-foliate 

 leaves with broad and crowded leaflets partly overla])j)ing at the subcordate 

 base.
