Rodin, Robert J. (Calif. State Polytechnic Coll., San Luis Obispo.) Anatomy of the reproductive bracts in Welwitschia . Amer. Jour. Bot. 50 (7): 641–648. Illus. l963.—The anatomy, including venation patterns, of the nodal bracts, sterile cone bracts, and fertile cone bracts of male and female cones is discussed. Two traces which dichotomize are present in each member. Occasional anomalous traces in the perianth have been discovered. Details of sclereids, fibers and gum canals are given. The connate nature of the bracts is described. The homologies of these organs are suggested.
