Recognizing and Identifying Meadow Grasses as a Guide for Nature Lovers, Botanists, Farmers, and Foresters - a nature guide from 1906. Illustrated with 96 black and white images. Meadows, like pastures, are a habitat that has been created and maintained by humans for several millennia. The selection pressure from mowing favors plants that thrive under frequent cutting and high light exposure, including many grasses. Botanically, grasses belong to the order of Poales; the two main groups are true grasses and sedges. Grasses first appeared in the Cretaceous period, after which the erosion behavior of the affected landmass changed significantly. Reprint of the original edition, 4th edition from 1906.
