NORTHWESTERN PLANTS. 173 



stipules, 5 mm . long ; peduncles slender, axillary from all or 

 nearly all the cauline leaves which they exceed, as well as from the 

 bracts, simple or the lowermost branched, each bearing a cymose 

 cluster of 6-12 flowers; calyx 4 mm. long, the attenuate triangular 

 lobes as long as the campanulate tube; petals white, broadly 

 spatulate, or obovate, 4 mm, long. 



Collected by F. H. Lamb, No. 1267, iat New London, Chehalis 

 County, Wash., 10 June, 1897. 



I have considerable hesitancy in describing this plant even as 

 a variety, but its habital characters are so different from typical 

 B. major Gray as to merit attention. The principal differences are 

 the smaller flowers on axillary peduncles and the smaller leaves 

 which are not reniform at all. The whole aspect of the plant is 

 very similar to B. occidentalis T. and G., which suggests a possible 

 hybrid origin. 



Rudbeckia alpicola. Stems stout, 1-2 meters high, striate, 

 glabrous below, sparsely pilose above with short white hairs; leaves 

 broadly ovate in outline, sessile or nearly so, rather harshly pubes- 

 cent on each side, 12-20 cm. long, all but the uppermost pinnately 

 3 to 5-parted, the lateral lobes lanceolate, the terminal one ovate 

 and much larger, all sparingly dentate with larger teeth ; head 

 single, ray less, in fruit 6-8 cm. long; involucre consisting of about 

 20 bracts, these green, lanceolate, acute, 3 em. long; disk cylin- 

 drical ; chaff-scales boat-shaped, pubescent at apex, slightly longer 

 than the achenes ; achenes 4-angled, 5 mm. long, with a four- 

 toothed pappus, which is not at all or only very slightly coroniform. 



Mt. Stuart, Kittitas County, Wash., July, 1898, A. D. E. Elmer, 

 No. 1171, at about 4,000 feet altitude. 



Nearest R. montana Gray, from which it differs principally in its 

 achenes, and its foliage, which is pubescent but not at all glaucous- 

 In some respects the plant is intermediate between R. montana 

 Gray and R. occidentalis Nutt. 



Senecio Elmeri. Perennial, with horizontal creeping root- 

 stocks, forming rather dense mats ; whole plant early glabrate by the 

 disappearance of a white tomentum, this most persistent on the 

 involucre; upright shoots 12-20 cm. high, nearly equaled by the 

 leaves ; radical leaves spatulate-oblanceolate, mostly obtuse, rather 

 thickish, saliently and somewhat unequally dentate, the blades 3-6
