Discussion | East Africa, Asia, Europe, North America, South America. 15 genera; 3 genera treated in Flora. The structure of the pistil in Berberidaceae can be confusing, and its homologies are uncertain. Berberidaceae taxa have a single pistil with a single unlobed stigma and an ovary having a single locule. Most taxa have one or a group of basal ovules. A few taxa (including Vancouveria) have more complex pistils, but their structure is difficult to interpret. It is uncertain whether the pistil evolved from a single carpel, like the pistils of Ranunculaceae, or from several fused carpels, as in Papaveraceae (Cronquist 1981). |
