silicula

(silicle) A dry dehiscent fruit derived from two carpels fused together to form a flattened pod with two loculi separated by a false septum. The seeds are exposed on the septum as the two valves separate from it, from the base up. Siliculae are similar to *siliquae, except that they are as broad or broader than they are long. The fruits of shepherd's purse (Capsella bursa-pastoris) are an example.
