than the description. The locality cited by Rafinesque may be 
wrong, but it is worth while to record that his specimen is pre- 
served. 
ASTER CORDIFOLUS, L. var. INCISUS, n. var. 
Leaves all lanceolate, glabrous, sharply serrate, or the lower 
incised, none of them cordate at base. Pocono Mountain, Penn. 
(Moser, 1832); near Riverdale, N. Y. (Bicknell, 1891). 
Dr. Gray alludes to Moser’s Pocono specimen in the Synop- 
tical Flora as an extreme form of A. cordifolius. This plant ap- 
pears to me worthy of varietal rank. It is nearest var. Zanceola- 
tus, Porter, BULLETIN, xvi. 68. 
POLEMONIUM VAN-BRUNTIA&, n. sp. (Plate CXXXI). 
Rootstock stout, horizontal. Stems erect, glabrous below, 
somewhat glandular-pubescent above, 6-8 dm. high, leafy 
to the top; leaflets of the lower leaves 15-19, short-peti- 
oluled, or sessile, ovate or lanceolate, 114-3% cm. long, 
5-15 mm. wide, those of the upper ones fewer; cymose clus- 
ters panicled or solitary, rather loosely 3-8 flowered; flow- 
ers bluish-purple, 15-20 mm. broad; petals rounded ; calyx 
5-lobed to about the middle, much enlarged in fruit, the lobes |

In cold, wet places, New York—Herkimer Co. (Clinton); 
Delaware Co. (Gilbert); Schoharie Co. (Howe); Ulster Co., 
Balsam Lake (Mrs. Van Brunt); Alder Lake (Rusby) ; Chenango 
Co., Preston and McDonough (Coville, BULLETIN, xii. 53); Tie- 
ga Co., near Appalachin (C. D. Fretz, BULLETIN, ix. 72).

This fine species has always been referred to the European P 
cwruleum,L.,from which it differs in its horizontal stout rootstocks, 
more leafy stem, exserted stamens, rounded (not mucronulate) 
petals, accrescent calyx which becomes twice or three times the 
size of that of P. cwruleum, broader and fewer leaflets, and fewer 
ovules. I take pleasure in dedicating it to the lady who has suP- 
plied such fine and numerous specimens by means of which the
