Bøger af William C. Coker

This volume contains descriptions of direct observations on, and illustrations of all known American species of the family Saprolegmiaceae. Notes are added on related families, as Leptomitaceae, Blastocladiaceae, and Monoblepharidaceae. Originally published in 1923.

Here one finds descriptions of 239 native trees, 22 foreign trees - now escaped from civilization and become wild - and a list of native shrubs that occasionally reach tree size. Almost every description is illustrated with drawings showing typical leaves, flowers, and fruits. Complicated technical terms have been avoided. Originally published in 1937.
