and broad; the inner series longer and narrower, scarious mar- 
gined all around: corolla resin-dotted throughout, 8—-1o™™ long, 
the broadly linear lobes half as long as the tube which is stiffly 
pubescent within near the base: style branches as long as the 
corolla; akene narrowly obovate, dark brown with short whitish 
spreading pubescence, about 5™™ long: receptacle nearly plane, 
with shallow alveolations. 
The plants upon which this species is founded were collected 2, ae ane 3 
Kimmons, August 1895, in the Creek Nation, I. T., and distributed by Pro- 
fessor J. W, Blankinship as Liéatris scariosa Willd. From this there are 
many Characters to separate it, but attention need only be called to the 
reflexed lower leaves, the long foliar-bracted spike, and the alate bracts of 
involucre. 
Lacinaria ligulistylis, n. sp.— Perennial, from an enlarged 
woody tuberous root: stems single, light green, glabrate below, 
lightly white pubescent above, striate, 4-5" high, uniformly 
leafy from the base up: leaves bright green, rather obscurely 
punctate, glabrous, usually minutely ciliate on the slightly thick- 
ened margin; the lower lance-oblong, 8—12™ long, tapering into 
a usually much shorter margined petiole; upwardly becoming 
more lanceolate, the winged base shorter, gradually smaller, 
passing into the lance-linear bracts of the inflorescence: heads 
from few to several, racemose: peduncles 1.3% long, tinged 
with purple as are also the peduncle and rachis: involucre 
broadly campanulate, often 20-25™" broad; bracts in about 6 
series, foliar-green with dark purple scarious dentate margins; 
the outer short, from nearly orbicular to oval; the middle rows 
broadly obovate; the inner elliptic or oblong and 15-18™™ long: 
flowers 50-70, purple: corolla tube slightly dilated upward; the 
teeth lanceolate, one third as long as the tube, with a delicate 
marginal vein: exserted style branches flattened, as long as the 
Corolla, light purple, conspicuous and superficially suggesting the 
Slender rays of some Erigeron; akene flattened, finely pubescent, 
Nearly as long as the corolla tube. 
The Rocky mountain forms of Lacinaria that have passed as L. scariosa 
(L.) Hill are clearly distinct from the eastern forms. That, even with the 
Rocky mountain form eliminated, L. scariosa, as applied to the eastern forms,
