Sorbaria arborea, var. glabrata Rehder, n. var.

 interdurn ad costam mediam minute puberulis, panicula glabra v. 

 tantum in parte inferiore tomento floccoso cito deciduo vestita.

 July and October 1907 (No. 499). Eastern Szech'uan: South 

 Wushan, A. Henry (No. 6245). Western Szech'uan: West of 

 Kuan Hsien, thickets, alt. 2100-2700 m., August 1910 (No. 4475); 

 Pan-lan-shan, west of Kuan Hsien, woodlands, alt. 2500 m., Septem- 

 ber 1910 (No. 4476); around Sungpan, thickets, alt. 2400-2700 m., 

 August 1910 (No. 4477); Mupin, woodlands, alt. 2400-2700 m., 

 October 1910 (No. 4340). 



Differs from the type chiefly in its glabrous foliage. The Hupeh plant, which 

 I consider as representing the type of this variety, has the leaves generally oblong- 

 lanceolate to lanceolate, the inflorescence narrower with ascending branches and 

 the stamens sometimes nearly three times as long as the petals, while the Szech'uan 

 form has the leaflets generally oblong-ovate or oval-ovate, the inflorescence loose 

 with spreading branches and the stamens less than twice as long as the petals. 

 No. 4340 differs again in the more closely set veins of the leaflets, resembling in 

 this respect the var. subtomentosa.
