mentis liberis ^ villosis, antheris flavis ovato-oblongis ; bracteae late 

 ovatae, apice rotundae, glandulifcrae, flavo-brunneae, utrinque sericeo- 

 villosae, filamentis duplo breviores; glandula ventralis oblonga, satis 

 crassa, bracteis vix duplo brevior, saepe incisa, dorsalis paullo brevior, 

 saepe bifida. 



Western Szech'uan: west of Kuan Hsien, Pan-lan-shan, thickets, 

 2300-3000 m., June 1908 (No. 2155, type; very large bush or tree, 7-12 

 m.; d"); same locality, October 1910 (No. 4352; bush 2.6-4 m.; 

 sterile) . 



A striking species, exceedingly well marked by its very long and distinctly reticu- 

 late leaves and by its long slender male aments. It seems most nearly related to 

 S. phaidima Schneider, which has the same long and narrow aments. 



The specific name is derived from (j>avep6s, distinct.
