The capsule opens transversely by a circular fissure across the middle. Along the line of dehiscence the cells are elongated transversely (Fig. 173, c), and are but slightly attached, while above and below they present irregular outlines, which tend to keep them together. We have two species : one perennial, with a campanulate pale-pink corolla, A. tenella; the other annual, with a rotate deep-red, pink, blue, or white corolla, A. arvensis. The seeds are dark brown, biconvex, flattened on the dorsal aspect by pressure against the wall of the pericarp, and covered with obtuse, broad-based teeth, which give them the appearance of being deeply pitted. A. arvensis.—The flower is open from about 9 to 3 , and it is interesting from this point of view that the only insect visitor yet recorded (Halictus morio) belongs to a genus which also goes to rest early. When the corolla closes, the stigma would probably come in contact with the anthers. Moreover, the corolla drops early, and in slipping over the pistil can hardly fail to dust the stigma with pollen.
