nomen nudum and we have no other clue than that of locality. 

 The species apparently has its home on this plateau below Waha, 

 for it is very abundant there. 



In the second line from the bottom of page 296 of Vol. 2, 

 Part I., of the Synoptical Flora, occurs this statement : " E. an- 

 gustifolia Nutt, 1. c, a low and small-flowered subalpine form ; 

 same as C. desertorum Geyer." If Dr. Gray actually saw this 

 plant of Geyer's and also Nuttall's there is no ground whatever 

 for supposing that our plant may be identical with Geyer's, for I 

 have seen the type of Nuttall's Euchroma angustifolia, and it is 

 very distinct from ours, as is also indicated by his original descrip- 

 tion in Journ. Acad. Phila. 7 : 46. 1834. 



Valeriana occidentals. 





Rootstalk moderately stout, ascending, somewhat branched ; 

 roots numerous; stems rather stout, 6-8* dm. high, puberulent, 

 especially below; basal leaves ordinarily about 25 cm. long, ellip- 

 tical-lanceolate, bluntly pointed, the'petioles occupying more than 

 half of the total length ; stem leaves on short clasping petioles, 

 which are ciliate on the lowest pair, ovate-lanceolate in outline, the 

 lower ones 10-12 cm. long, and composed of about four pairs 

 of leaflets, these lanceolate and acute, the lowest pair the smallest, 

 while the single terminal leaflet is several J:imes larger than those 

 of the pair next beneath it ; inflorescence' much elongated, com- 

 posed of from three to five pairs of opposite branches, the lowest 

 internode about 12 cm. long, the others growing successively 

 shorter ; the lowest flower branches subtended by a bract-like 

 leaf, which is parted into three linear-lanceolate lobes, the other 

 flower stalks provided with narrow linear bracts ; flower branches 

 approximately as long as the internodes, surmounted by a three- 

 branched cyme, each branch of which is again subdivided into two 

 or three branches, the' pedicels slightly pubescent or puberulent ; 

 calyx glabrous, the lobes linear-lanceolate, prominently one-nerved ; 

 corolla creamy white, short, with barely half its length exserted 



from the calyx, the tube only half the length of the throat and 



stigma entire. «..»/
