Marshallia grandiflora n. sp. Plate I. 



A perennial herb 3. 5-7 dm tall: radical leaves 5cm_ 2 dm long 

 including the petioles, i-2 cm wide, varying from lanceolate to 

 ovate-lanceolate in outline, obtuse at the apex and gradually 

 narrowed at the base and prolonged into broad petioles as long 

 as the blades : stem-leaves ovate-lanceolate, i-3 dm long includ- 

 ing the petioles, i-3 cm wide, gradually diminishing in size up 

 the stem to leaves i-4 cm long and 3-7!™ w ide ; they are obtuse 

 at the apex, or the uppermost acutish, gradually narrowed into 

 broad petioles as long as the blades, firm in texture and 

 displaying 3-5 prominent nerves :- stem angled and striate, 

 glabrous except the peduncle, which is minutely scabrous- 

 pubescent : involucre ymm-jcm high, the bracts oblong-lanceolate, 

 acute at the apex, glabrous, and with narrow hyaline margins, 

 7 mm -i cm long, 2-3 mm wide, thin in texture at flowering time, the 

 midrib slightly thickened : florets i.5-2 cm long: corollas slender, 

 pubescent, the tubes about i cm long, the upper third conspicuously 

 dilated : pappus scales entire, sharply pointed, about 2 mm long : 

 mature achenes ribbed and hairy, 4-5 mm long, i.5-2 mm broad: 

 chaff of the receptacle linear, pointed. 



Marshallia grandiflora was collected in full flower July 22, 1898, near 

 Saluda, Polk county, North Carolina (type locality), and is also represented in 

 the Biltmore Herbarium from a station near Hendersonville, North Carolina, and 

 Upshur county, West Virginia (W. M. Pollock, July 4, 1896). The proposed 

 species is related to M. trinervia (Walt.) Porter, 1 c, from which it may be dis- 

 tinguished by the longer and thicker leaves and larger heads and florets. The 

 type material is preserved in the Biltmore Herbarium. 



Mostly in moist soil, western North Carolina to West Virginia and Pennsyl- 

 vania.
