Marshallia mohri n. sp. Plate III. 



A perennial herb 4-7 dm tall : leaves ovate-lanceolate, i.5-2.5 dm 

 long, including the petioles, i.5-3 cm wide, the uppermost much 

 reduced in size, obtuse at the apex or the upper acute, gradually 

 narrowed at the base and prolonged into petioles as long as or 

 longer than the blades, the uppermost sessile ; they are promi- 

 nently 3-nerved, glabrous and in age firm in texture, entire : stem 

 angled, striate, glabrous to near the top, branched above the 

 middle : heads usually several, containing from thirty to seventy- 

 five or more flowers : involucres 5-8 mm high, the bracts thin at 

 flowering time, ovate-lanceolate, acute at the apex, 2-3 mm wide 

 with conspicuous hyaline borders below the middle: florets i-i.5 cm 

 long : corollas slender, pubescent, the tubes about J mm long, 

 slightly if at all dilated at the throat : pappus scales 2 mm long, 

 acute, the borders broken by a few sharp points : achenes ribbed, 

 very hairy : chaff of the receptacle linear, acute. 



Marshallia mohri closely resembles M. grandiflora, above proposed, but 

 may be recognized by the smaller heads and florets and by the absence of the 

 dilated corolla tubes so conspicuous and noteworthy in the last-named species. 

 The type specimen was collected by Dr. Charles Mohr, for whom the species 

 is named, at Cullman, Cullman county, Alabama, June 24, 1893, and is pre- 

 served in the Chapman Herbarium at Biltmore.

 clustered from a perennial root : radical leaves linear-lanceolate, 

 5 cm -i.5 dm long including the petiole, 5-8 mm wide, obtuse at the
