These navrow-leaved Sedunis of the Japonica series, which often recall 

 the moss I'olytrichum in appearance, now constitute quite a large group; 

 they range from the Himalayas to China, and are closely related and difficult 

 to diao-nose. Pi. Hamet, to whose careful work our knowledge of most of 

 them is due, at first^ placed importance on the erectness or divergence of the 

 fruitino- carpels, thus separating from the rest S. nmdticaule Wallich and 

 S. Heckeli R. Hamet (both with divergent carpels), which he placed with a 

 series of mostly broad-leaved stellate-fruited species which belong to eastern 

 China, Japan, and the Philippines. More recently,^ however, he unites these 

 two species with their Sino-Himalayan narrow-leaved congeners. 



From all Asiatic Sedums the present species can be distinguished by its 

 combination of lanceolate acute verticillate leaves and divergent fruit. The 

 leaf-character separates it from S. dri/'nianoides Hance, S. filipcs Hemsley, 

 and S. Silvestrii Pampanini, which are white-flowered, broad-lea-\'ed species 

 of the series Cepaea ; also from S. Bergeri R. Hamet (with linear-spafhidafe 

 verticillate leaves), and S. Yvesi Pi. Hamet (with obovafe-linear blunt verticil- 

 late leaves), to both of which S. cpiafernatum appears closely related ; while 

 its divergent carpels distinguish it from all its allies except S. multicanh and 

 S. Heckeli, which have alternate leaves. It comes nearest to S. Tvesi, in 

 which, however, in addition to the difference of leaf, the flowers are stalked 

 (not sessile), the sepals linear (not oblong-lanceolate), the petals ovate (not 

 lanceolate) and the scales obovate-cuneiform (not quadrate;.

This appears to be a very variable species. The present specimens belong 

 to the southern race as described by Maximowicz (Bull. Acad. Imp. de 

 St. Petersbourg 29 155), with large opposite lower leaves and truncate scales. 

 The sepals in Bailey's plants appear to be unusually short (■^, not ^ or ^- the 

 petals) and are deltoid rather than ovate, the petals lanceolate rather than 

 ovate, and the pedicels 3-4 times (not twice) the flowers. Of the articulation
