Piper : Noteworthy Northwestern Plants 393 



no. 2246. Nearest P. Breiveri Watson, but easily distinguished 

 by its 1 -flowered peduncles and villous carpels. Apparently it is 

 the only North American species with pinnate leaves and strictly 

 one-flowered peduncles. 



J Saxifraga Columbiana sp. nov. 



Scapes rather stout, terete, erect, glandular, usually solitary 

 from the caudex : leaves all radical, ovate to elliptic-oblong, ob- 

 tuse, entire, the blades 2—6 cm. long, gradually narrowed into a 

 somewhat shorter petiole : inflorescence a branched narrowly pyra- 

 midal cyme, the cymules rather dense : bracts lanceolate or linear : 

 flowers 5—6 mm. in diameter on stout pedicels : calyx-lobes trian- 

 gular ovate, obtuse, at length reflexed : petals whitish, elliptic or 

 oblong, 1 -nerved, slightly narrowed at base, shorter than the calyx 

 lobes : filaments subulate, about equaling the petals : anthers 

 pale yellow : carpels separate, divergent at apex. 



Nearest Saxifraga plantaginea Small, which is a larger plant 

 in every way. Both these species differ from others of the integ- 

 rifolia group in that the petals are shorter than the calyx lobes. 

 In the species here described the petals are very different in shape 

 and size from those of *S. plantaginea. 



The following specimens have been examined : 



Washington: Near Fort Colville, Lyall in 1861 ; " upper 

 Oregon/' Geyer, no. 625 ; Pullman, Piper, no 1508 (type). 



Idaho : Near Lewiston, Sandberg, MacDougal and Heller, no.

 * 



Scapes stout, terete, erect, solitary, glandular pubescent, 1-2 

 dm. tall : leaves all radical, oval, oblong or ovate, obtuse, entire 

 or obscurely denticulate, glabrous except the ciliate margin, the 

 blade 1-3 cm. long, narrowed into a broadish petiole a trifle 

 shorter : inflorescence dense, 1-2 cm. long : flowers very short - 

 petioled, green : calyx-lobes broadly ovate or suborbicular, obtuse, 

 erect, 2 mm. in length, the tube twice as long : petals wanting : 

 stamens ten, the anthers pale yellow on subulate filaments nearly 

 as long as the calyx-lobes : carpels disciform when young, the 

 margin crenulate : mature fruit not seen. 



The type is G. R. Vasefs no. 358, collected somewhere in 

 Washington in 1889 ; the same plant has been found by Whited in
