94 JOLTIXAL OF THE ARXOLD ARBORETl^M [vol. i 



iypQ specimens, collected probiiljly near Monterey, and Bolander's poor and 

 luicerLahi sj)ceinien from Marin County. Tlierefore, Uebb, at this time and 

 in 18i)l, ret;arded S. CouUeri iv^ representing ''nothing more than an abnor- 

 mal developinent of S. sitchcusis.''^ Judging by the material enumerated 

 below it seems to me that S. Coulteri, although certainly closely relafeN:! to 

 S, .silchensls, nevertheless presents some j>ec;uliar characters of its own 

 which lead me to kcej> it as a s]>ecics until more abundant material con- 

 \-^nces me tliat no rigid line can }x* drawni between fhe two species. The 

 diirerence in the pul)escence of their leaves is mucli the same as that be- 

 tween S. suhoeridea and S. hdhi or ^. pelliia. In S. Coulteri the rather rigid 



old leaves bear a much more woollv and dull felt-like tomentum on their 

 lower surfaces, which often is rather yellowish on the young leaves at lh<* top 



of the branehlt'ts which are clothed with the same kind oF ]>ubes('(Mie(\ 'I'lie 

 lowermost (^rst) leaves and those of the peduncles show a more or less 

 shining covering of long silky adpresstvl hairs. The anuMifs are more shni- 

 der than those of S. sifchensisy the yellowish or light bro^^'n bracts are more 

 lustrous silky, and the anthers a^e golden yellow. The fruiting aments 

 somctimr^s measure up to 13:1.3 cm., and the well-matured fruits are usu- 

 allv from 0.;> to 1 mm. sliorter tlian those of S. sifcJiensis. I refer the follow- 

 ing sj)ecimens to S. Coulteri.
