2. Delphinium tricorne Michx. Rock Larkspur. Map 943. Infrequent 

 to frequent in rich soil on wooded slopes in the southern counties, becom- 

 ing less frequent northward and probably very local or entirely absent 

 from the northern two tiers of counties. It seems to have very little affinity 

 for streams, because it is usually found near the bases of slopes of 

 ravines as well as along streams. This wild species is easily cultivated 

 in the garden. I have a specimen which I collected on May 1, 1910, in 

 a woods near Wilson Creek northwest of La^wrenceburg, in Dearborn 

 County, on which I have the following note: "In this station I estimate 

 that there is an average of 1 plant for every square foot of space over an 

 area of 20 acres of woodland." I have seen it in large colonies but usually 

 only a few plants are found at a station. The plant is poisonous to stock. 

 I met a farmer who lived a mile north of Cedar Grove in Franklin County 

 who called the plant stagger weed and told me that he had known cattle 

 to be killed by eating it.

2540. ACONITUM [Tourn.] L. 



1. Aconitum uncinatum L. Clambering Monkshood. This species 

 was reported by Short in his Fourth Supplement of the Plants of Ken- 

 tucky as occurring in the "barrens" of Indiana. On January 1, 1927, I 

 found, in the herbarium of the Philadelphia Academy of Sciences, two well 

 preserved and ample specimens of this species collected by C. W. Short. 

 The labels are as follows : "Barrens of la. near Corydon, Sept. 1840" and 

 "Barrens of Indiana near Corydon, Oct. 1842." The identification of the 

 specimens is correct. The species may be extinct in Indiana.
