The occurrence of the prostrate Juniper (Juniperus horizontalis) in Iowa is so unusual that an account of the habitat and associates will be of interest. Some years ago Mr. C. L. Webster and Mr. H. Clark Brown of Charles City sent me some specimens of this savin which Mr. Brown said was native to this general region. Its occurrence was so unusual that I felt it might have been introduced. During July, 1922, the writer, Professor G. B. MacDonald and Mr. C. L. Webster visited the place and observed the plant, which covers an area of some ten acres on the northerly slope of a hill about half a mile south of Lime Creek near Rockford. This shrub occurs on shaly prairie hills with many fossil shells lying on the ground. The region is therefore an interesting one from the standpoint of geology as well as botany. A brick and tile factory attests the value of the shaly material for the making of brick and tile.
