Tennessee: Knoxville, Ruth, September, 1894. 

 Mississippi : Agricultural College, Pollard, no. 1267. 



Lacinaria Halei 



Perennial, glabrous or nearly so. Stems erect, 6-9 dm. tall, 

 simple or sparingly branched : leaves various ; lower with linear 

 blades 1-2 dm. long, upper narrowly linear and much shorter, not 

 ciliate near the base : heads short-peduncled or nearly sessile, not 

 densely crowded : involucres becoming narrowly turbinate, 7-9 

 mm. high : bracts lanceolate to oblong-lanceolate, acuminate, cil- 

 iolate, rigid : pappus plumose : achenes closely pubescent. 



On prairies, Louisiana. Summer. 



This species has heretofore been included in Lacinaria acidota, 

 with which it has little or nothing in common, and it may be sep- 

 arated by its fewer leaves and much smaller heads which are dis- 

 posed in elongated interrupted spikes. The bracts of the involucre 

 are much shorter than those of L. acidota and have less elongated 

 tips. 



The species is founded on Hale's no. 334. 



Lacinaria platylepis 



Perennial, bright green. Stems erect, 8—9 dm. tall, simple, 

 glabrate below, pubescent with white hairs above : leaves not very 

 numerous, narrowly linear, 2-10 cm. long, or longer at the base 

 of the stem, glabrous or nearly so : heads rather approximate, 

 sessile, surpassing the subtending bracts : involucres cylindric- 

 campanulate, 7—9 mm. long ; outer bracts often ovate, acute, inner 

 larger and broader, broadest above the middle, rounded at the 

 apex, ciliolate : pappus not plumose, pale. 



In sandy soil, Louisiana. 



Plants belonging here have been referred to Lacinaria acidota. 

 although none of the several characters warrant such a disposition, 

 The fewer and shorter leaves, the elongated more or less inter- 

 rupted spikes and smaller heads and involucres with their broad 

 rounded inner bracts, are some of the characters that separate 

 Lacinaria platylepis from L. acidota. The pappus too is not plu- 

 mose. 



The original specimens were collected in Louisiana by Dr. 

 Hale.
