Another variety, with the ovate-oblong cauline leaves rounded to 
the base but with the stems, petioles, and often the lower surfaces of 
the leaves densely villous-hispid, is found in dry woods from Kentucky 
and North Carolina to Florida and Louisiana. This is Rafinesque’s 
Brunella cinerea, recently described by Pollard & Ball as a new variety, 
P. vulgaris scaberrima,' but it closely matches material received at the 
Gray Herbarium from Bentham of his P. vulgaris, a hispida? from 
India and southern Europe. It would seem, therefore, that var. 
hispida, like the plant which Bentham called var. elongata (P. penn- 
sylvanica, var. lanceolata Barton), is indigenous in America as well as 
in Eurasia, though of less boreal range on both continents. 
The preceding discussion may be briefly summarized as follows: 
A. Principal or median cauline leaves ovate or ovate-oblong, rounded at 
base, 2-1 (averaging 4) as broad as long B. 
B. Plant EY and not conspicuously pilose. 
Corolla bluish, violet or lavender.................. P. vulgaris. 
Corolla EI... eller P. vulgaris, forma albiflora. 
B. Stems, petioles, and often the lower surfaces of the leaves densely 
villous-hispid with white pubescence.................. var. hispida. 
D. Bracts green or at most with purple-tinged margins, glabrous to 
sparingly pilose on the back. 
Calyx pe or at most with purple-tinged margins. 
Corolla bluish, violet or lavender............ var. lanceolata. 
Corolla white................ var. lanceolata, forma candida. 
Calyx purple. 
Ce la bluish or violet...... var. lanceolata, forma iodocalyz. 
Corta pink......... 00: 55 var. lanceolata, forma rhodantha. 
D. Bracts and calyx dark purple, the former densely tomentose or 
lanate on the back...................... FTT var. aleutica. 
C. Bracts of the inflorescence with glabrous or sparingly short-ciliate 
margins. 
Leaves and stems glabrous or essentially so; bracts green, or at 
most with purple-tinged margins; corolla violet.var. calvescens. 
Leaves pilose beneath: stems pilose: bracts mostly deep purple: 
corolla dark or blackish purple............. var. atropurpurea.

3 In his New Flora, pt. 2, 29-32 (1837) Rafinesque described ten species of Brunella 
from eastern America. Without authentic specimens it is impossible to identify 
them with certainty. B. microphylla and B. sessilifolia seem too indefinite for a 
guess. B. heterophylla, cordata, and obtusifolia are presumably B. vulgaris; B. petio- 
laris, hirsuta, and reticulata are referred to var. lanceolata or one of its forms; B. rosea 
may possibly be the same as the plant here called var. lanceolata, forma rhodantha; 
and B. cinerea, from its description and range, is almost certainly var. hispida.
