D ede , R oland A. (California Concordia Coll., Oakland.) Foliar venation patterns in the Rutaceae . Amer. Jour. Bot. 49(5): 490–497. Illus. 1962.—A study of herbarium specimens selected from 80 genera of the Rutaceae revealed a series of 7 venation types. The series is based on the spatial relationship of the venation system to the secretory cavities. The hypothesis is advanced that the uncorrelated venation pattern is primitive and that the more complex types represent end products involving a branching pattern of phylogenetic sequences. A key to the illustrated representatives of the 7 types is included.
