That's right, I am going to give you the location of some cp's that I found today. I didn't have my GPS but I will get you very close with Google earth. Unfortunately I don't have pics because my camera battery died just minutes before I found these plants. The only plants I saw was D.capillaris. This site is in Wilmington NC. If you ever want to visit the site you can get the coordinates off of the google earth pic I saved. Google Earth is known for not being very exact, but it'll get you to the area for you to search. You must also get permission from the land owner to access the property. I can promise you they will prosecute you if they find you on their property without permission.
There you go. I can promise you that you will find D.capillaris at this location within a few feet of the marker.
If you ever get to the location send me the pics, since I didn't get to take any today.
