ones of the upper series and sometimes overtop most of its leaves, 
though they do not reach the inflorescence. Its heads are quite 
small-sized and subsessile, often in a long, spike-like raceme. 
It is a handsome variety, and was collected by Mr. Chas. C. Deam 
in Warren County, Ind., on the top of the sandstone biuffs of 
Pine Creek, 2 miles above Mudlavia, Sept. 11, 1911, bearing his 
number 9986. 
Theevar. superans is about 3 dm. high, with a lax, narrow 
spike of short-pedicelled or subsessile heads occupying ’%—% of 
the stem. The type was collected by W. W. Calkins, on August 5, 
1876, at Black River, Wis., as Liatris spicata, bears his number 
869, and belongs to the University of Notre Dame herbarium. 
The var. Nieuwlandii. Stem not unusually 1 m. high, simple 
or even branched (then with few-headed branches), with a few- 
headed, short-pedicelled, narrow, short inflorescence to an ample, 
many-headed, long-pedicelled or long-branched one, and with 
an ample, brilliant green foliage. This color is so striking that it 
enables one easily to distinguish this variety from its relatives. 
Involucral bracts bright green over the whole surface, or with 
narrow, mostly almost entire purple margins. The name is in 
honor of Prof. Nieuwland. One of his plants, numbered 406 and 
collected at Notre Dame, Ind., has an almost corymbose inflo- 
rescence. Mr. Deam has a varied, excellent selection of this 
plant from a number of places in Indiana, marvelously showing 
its different phases. I believe this variety surpasses all its kin 
in magnificence. I thought that the following forms perhaps 
would deserve separate names: 1. forma borealis, whose short 
stem and short, few-headed raceme bespeak its northern origin 
(no. 1680, Herbarium of the University of Notre Dame), col- 
lected by Prof. Nieuwland at Detroit, Mich.; 2. forma versicolor 
with its blackish purple bracts, collected by Mr. Chas. C. Deam 
in various places of Indiana, in sunny, exposed localities; and 
3. forma gracillima, remarkably long and slender, collected by 
Mr. Chas. C. Deam on prairie soil in Steuben Co., Indiana. 
The distinguished var. salutans has its type located in Mr 
Deam’s herbarium, for which it has been acquired from Biltmore 
Herbarium, collected Sept. 23, 1903, near Houston, Harris Co., 
Texas, bearing its number 2670j, and named L. scariosa. 
The var. petiolata is usually a tall, slender plant, with rather 
long, narrow, often falcate and often perfectly glabrous leaves
