316 PITTONIA. 
I thus propose, for a new subspecies, what is known 
throughout a great extent of country west of Lake Michigan, 
as V. sagittata. It is common in southern Wisconsin, occu- 
pying rather low pasture and meadow lands, quite after the 
behavior of true V. sagittata at the East and South. An 
excellent flowering specimen, collected by myself near 
Albion, Wis., just thirty-two years ago, and still in my herba- 
rium, well represents the species; though the description of 
the flower is here drawn from living plants now blossoming 
within my reach; for a year ago I had specimens sent me 
in the living state, which I at once planted in a piece of wild 
land occupied by V. sagittata, where they have flowered beau- 
tifully thisspring. By the side of true V. sagittata this western 
species appears quite as a dwarf, in all except its corolla, this 
being about twice as large as that of V. sagittata. But the 
plant has the pubescence of V. ovata, to which, by the way, 
it has been referred, in some of the herbaria, since V. ovata 
came to be generally recognized as a valid species. 
True V. sagittata seems to reach central Illinois, and even 
the southern peninsula of Michigan; but I have not seen it 
from Wisconsin, nor V. subsagittata from any point to the 
southward or eastward of Wisconsin. 
V.suBCORDATA. Caulescent, erect, slender, 6 to 10 inches 
high, sparingly pubescent with minute stiff hairs, these 
somewhat appressed on the foliage, but on the petioles re- 
irorse; leaves thin-membranaceous, from deltoid-ovate and 
} inch long in the lowest to subcordate-ovate and 1 or 2 
inches long in the upper, all slightly crenate or crenate-den- 
tate, the very slender petioles 1 to 3 inches long; stipules 
linear-lanceolate, remotely but saliently serrate: flowers blue, 
very large, 1} inches broad, the very thick and obtusestraight 
spur 4 inch long or more. 
A very beautiful species, collected at Esquimault, Vancou- 
ver Island, 6 June, 1896, by Mr. James R. Anderson; the 
specimen preserved in the Canadian Survey herbarium.
