 brevibus divarieatis coronata; glandula una ventralis, ovato-oblonga,

Western Szech'uan: Chiu-ting-shan, thickets, alt. 2300 m., May 

 23, 1908 (No. 2124, type; 9 ). 



I am very doubtful if this species belongs to the section Longiflorae. In the 

 rather large leaves it resembles some forms of sect. Eriostachyae, but the catkins 

 are exceedingly small and thin; and 1 suspect a hybrid origin between a species 

 with glabrous and another with hairy ovaries. 



The specific name is derived from dfji(j)ij3dkos, doubtful.

Von Seemen and Burkill knew only the 9 plant. I add the description of the 

 & : Amenta cf subsessiUa, basi fohoUs 2 oblongis squamiformibus subtus dense 

 eericeis instructa, 3-5.5 cm. longa, circiter 0.8-1.1 cm. crassa, densissima, flaves- 

 centia, rhachi sericea; flores diandri, filamentis liberis tantum basi pilosis bracteis 

 2-23^plo longioribus, antheris ovato-oblongis flavis; bracteae oblongae, obtusae, 

 flavo-brunneae, utrinque dense sericeae, longe cihatae; glandula una obovata v. 

 claviformis, crassa, bracteis subtriplo brevior. Ceterum ut a cl. von Seemen v. 

 Burkill descripta. 



This handsome species has lanceolate entire leaves which are whitish beneath; 

 the fruits are about 5 mm. long, the pedicels being 2-4 times longer than the broad 

 gland. The shape of the glands is similar to that of those of S. tetrasperma Rox- 

 burgh, and von Seemen first beUeved that S. heterochroma might belong to sect.
