This asymmetral pattern suggests that these disseminules are mericarps of the kind typical for Apiaceae, with three or five longitudinal veins occurring on the dorsal side of each mericarp but only a single vein running medially on the ventral side.
Each valve or mericarp with two auriform wings spreading from an obovate thickened central body; veins irregular in course and spacing, with large areoles.
24k), and the other a dispersed mericarp retaining a portion of the stylar projection (Fig.
An additional smaller vertical wing may arise over the locular region of each mericarp.
We have excluded from this treatment schizocarpic fruits with laterally extended mericarp wings, e.
In the case of a 4-winged fruit, typically each dispersed mericarp will possess two wings.
