Berberis dictyophylla, var. epruinosa Schneider, n. var. 
A typo differt ramulis junioribus distinctius angulato-sulcatis, 
epruinosis, ruberrimis, foliis subtus epruinosis pallide viridibus, 
floribus ut videtur intensius coloratis. 
Western Szech'uan: Ta-p’ao-shan, north-east of Tachien-lu, 
thickets, alt. 3600—4300 m., July 1908 (No. 2866, type; bush 1-1.60 m. 
tall, lowers yellow); June 1904, ravines, alt. 5500 m. (Veitch Exped. 
No. 3146, 1 m. tall); and probably June 1904, woods, alt. 3800-4000 m. 
(Veitch Exped. No. 3145); only the fruiting branches! 
The type of Franchet has the leaves distinctly glaucous beneath and also pruinose 
twigs. This is the same in B. approzimata, described by Sprague in Kew Bull. 
Misc. Inform. 1909, 256. Sprague cites the plate 7833 of the Bot. Mag. which 
represents only a form of B. dictyophylla with copiously serrateleaves. The flowers 
of the plate are as large as on plate 11 of Franchet in his Pl. Delavay. Therefore 
I agree with Rehder in treating it as a variety of the type as B. dictyophylla, var. 
approximata Rehder in Mitt. Deutsch. Dendr. Ges. XX. 183 (1912).
