124 MISSOURI BOTANICAL GARDEN. 
DELPHINIUM CAROLINIANUM Walt. 
Common on the tops of all the mounds. The pistils are 
commonly from three to seven, as I have noticed in the 
plants of Jackson County, Missouri. (Watson No. 8.) 
AcTAEA ALBA (L.) Mill. 
Rarely seen on the wooded eastern slopes of the mounds. 
(Watson No. 9.) 
CLEOME SERRULATA Pursh. 
Abundant on the lower part of the mounds. Has a very 
fetid odor, on account of which it is called Stinking Clover 
by the country people. (Watson No. 16.) 
VIOLA PEDATIFIDA Don. 
Common all over the bare parts of the mounds. V. 
obliqua Hill (Watson No. 21), was common in the woods 
on the east of the mounds. (Watson No. 19.) 
Vioua PALMATA L. 
Very common along the bases of the mounds. (Watson 
No. 20.) 
Hypericum Ascyron L. 
On the northern sides of several of the mounds. At 
one mound, I estimated that there were between ten 
and fifteen thousand plants in one patch, about four miles 
northeast of Watson. (Watson No. 37.) 
Linum sutcatum Ridd. 
On the bare tops and sides of the mounds, usually with 
Gerardia aspera Dougl., which it not a little resembles. 
(Watson No. 42.) 
CEANOTHUS OvaTus Desf. 
Very common on the sides of the mounds, and appear- 
ing quite distinct from the next in appearance and mode of 
growth. (Watson No. 120.)
