342 WILSON EXPEDITION TO CHINA 



A distinct variety in some respects intermediate between var. tenuisepala 

 Maximowicz and var. lissocarpa Rehder & Wilson having the narrow sepals and 

 villose achenes of the former and the glabrous character of the latter. From both of 

 these and from other forms of this variable species it is distinguished by the charac- 

 ters described above. Though the leaves are thin in a dried state we suspect that 

 they are rather fleshy on living plants. In foliage it resembles somewhat C chinensis 

 Retzius, which is easily distinguished, however, by its linear-oblong anthers, 

 short filaments, pointed buds, paniculate inflorescence and firmer, usually narrower 

 leaflets, drying nearly black.

 We have seen no specimens of the type from China, but according to Maximo- 

 wicz it occurs in Kansu and northern China. It can always be easily distinguished 

 from P. orientalis L. by the sepals being glabrous except at the woolly margins.
