Abstract: | The seeds of twenty weedy species from four genera of the Convolvulaceae are keyed, described, and illustrated. Two types of hila are defined: 1) the ipomoea-type hilum is large, nearly circular in outline, usually emarginate at its base, and usually surrounded by a ridge and 2) the convolvulus-type hilum is small, wider than long, not emarginate, and not surrounded by a ridge. |
