lata), costa nervisque 2 pro 1 em. elevatis, margine distincte argute 
serrata, dentibus callosis apicem versus productis, sinuosa, 5-8 cm. 
longa, 3.2-3.8 em. lata, maxima usque 13 cm. longa et 5.2 em. lata; 
petioli 10-15 mm. longi, sericeo-villosi; stipulae ovatae v. semiovatae, 
&cutae, petiolis fere triplo breviores, ad apicem glanduloso-serratae, 
pilosae. Amenta fructifera ramulis subvillosis 2.5-4 em. longis folia 
3-4 normalia gerentibus suffulta, 9-14 cm. longa, circiter 1.5 cm. crassa, 
rhachi sericeo-villosa; flores (inter fructus remanentes) sessiles; ovaria 
ovato-elliptica, argenteo-sericeo-villosa, stylis bifidis quam stigmata 
oblonga bifida paulo longioribus coronata; bracteae late ovato-rotun- 
dae, brunnescentes, extus sericeae, intus (et interdum apice) glabrae, 
ovariis duplo breviores; glandula una ventralis oblonga, bracteis duplo 
brevior. Fructus circiter 6 mm. longi, subsessiles, ad apicem paulo 
attenuati, ut ovaria villosi. 
Western Szech'uan: west of Kuan Hsien, Niu-tou-shan, alt. 
2600-3000 m., June 1908 (No. 2154, type; bush 1.5-3.6 m.; with fruits). 
This species seems most nearly related to S. Ernesti Schneider, but differs 
clearly in its serrate leaves, the smaller bracts, the narrower gland and in the yel- 
lowish brown twigs. Unfortunately there are no c? flowers. 
The specific name is derived from dpyvpodeyy/s, shining like silver.
