This is a vintage botanical illustration featuring a bison standing next to a tree with a cascading plant growing from its branches. The bison is depicted in profile, with a dark brown coat and a short tail. It appears to be rubbing against the tree trunk. The tree has a forked trunk and is adorned with a lush, green plant that drapes down, covered in delicate, pink and purple flowers. The illustration is rendered in a watercolor style, with soft shading and attention to detail in the foliage and animal anatomy. The background is a pale cream color, typical of antique botanical prints. The overall composition is delicate and artistic, reminiscent of scientific illustrations from the 18th or 19th century.
