ARTYNIA PROBOSCIDEA Glox.—I know of but one sta- 
tion for this plant—on the banks of the Macoupin Creek, 
where it appears to be indigenous. 
The pale bluish corolla measures about 53 cm. in length, 
its tube about 3} cm. The tube within is finely spotted with 
bluish; on the lower wall there are about three orange lines 
leading from the narrow part of the tube and expanding ina 
large spot on the lower lip. The throat above is spotted with 
reddish, on the sides with bluish. The middle lobe of the 
lower lip is streaked with bluish and is straight, while the 
others are reflexed. 
= adaptation to long-tongued bees. I have found the flow- 
€ts in bloom from Aug. 19 to Sept. 14. Sept. 3, 1890, I saw 
Sombus americanorum F. % sucking the honey, its thorax be- 
ing streaked with pollen. 
: DIANTHERA AMERICANA L.—The plant is rather common 
= shallow Water of streams, the stems rising from 3 to 9 dm. 
§ small clusters of purplish flowers. : 
flowers are proterandrous. The two-lobed upper lip 
na €rect and is strongly marked with purple. The lower 
"a 1s formed by three widely divergent lobes, which are white, 
€ middle one with much purple.
