1015. Laciniaria fallacior Lunell, sp. nov. 



Stem 4-6 dm. high, from a horizonta 1 tuberiform rootstock, 

 which equals 6 cm. horizontally and 2 cm. transversely. Leaves 

 numerous, rough, more or less hairy, linear, the lower 4-6 mm. 

 wide, the upper narrower. Heads 15 -flowered in the smaller size, 

 with twice or thrice as many flowers in the larger ones (i. e., the 

 terminal and generally 1 or 2 lateral), 15-20 mm. long, sessile or 

 short-peduncled, crowded into a dense spike, interrupted and not 

 leafy below. Involucral bracts broadly ovate, acuminate, ciliate 

 on the margins, inbrieated in 5 or more series. Achenes pubescent. 



The species is closely related to L. punctata, which has a glabrous 

 stem, 1.5-3 dm. high, leaves glabrous, 2-4 cm. wide, heads 3-6- 

 flowered, of equal size, 10-15 cm - l° n g> sessile, crowded into a 

 dense, uninterrupted spike, which is leafy below, and achenes 

 glabrate or minutely pubescent.
