For a variety which is neither very well marked nor very 

 widely distributed this has acquired an abundant synonymy. 

 This is due partly to the scanty material to which Andersson 

 had access in 1858, partly to his neglect of NuttalFs work, 

 and partly to a confessedly sentimental desire on the part of 

 Mr. Bebb to perpetuate the name of Dr. Scouler in connection 

 with some western willow. 



iS, Scouleriana, as is well known, was founded by Dr. 

 Barratt on leaves of S. Silchensis and aments which were later 

 found to be a form of 8, Jlavescens. jS. flavescens Nutt., S, 

 brachystachys Benth., and S. capreoides Anders, were all 

 described independently, in 1842, 1857, and 1858, respectively. 

 Andersson having discovered, in 1858, the composite character 

 of 8. Scouleriana^ rejected the name and, in 1867, referred 

 the fertile aments of Barratt' s species to 8. brachystachys as 

 var. Scouleriana forma crassijulis^ ignoring Nuttall's name 

 entirely. He still considered Bentham' s brachystachys and 

 his own capreoides to be distinct. In 1880, Mr. Bebb, also 

 rejecting 8. Scouleriana, restored Nuttall's name and declared 

 8. brachystachys and 8. capreoides to be identical and hence 

 synonymous with S. Jlavescens Nutt. 



In regard to the publication of the name Scouleriana as a 

 variety o^ 8 . Jlavescens, there seems to be as much misunder- 

 standing as there was in regard to the specimens on which the 

 name was originally bestowed. Mr. Bebb, in 1880, had 

 rightly followed Andersson in rejecting it as a specific name. 

 But in 1882 he, wrongly and against his better judgment, 

 used it in establishing the new combination 8. Jlavescens var. 

 Scoideriana (Barratt) Bebb (Bot. Gaz. 7: 129). Later
