Hypericum perforatum 

 1. This is a common plant found in the field and along hedges and empty lots. The stem is two edged and is from one or two feet high. The leaves are lanceolate, marked with lines, and have a great many transparent points on the surface which look like perforations the edges of the leaves roll back; the flowers are in panicles, star shaped and yellow. The fruit forms four capsules with three valves. This is a brown red and shines like resin.”
