Buttercup and hepatica are flowers which have separate carpels; they are sometimes described as having many pistils. Thus it is evident that the word pistil sometimes refers to one carpel, sometimes to many. Like the word ovary, it is a name which was used before the real nature of flowers was understood. The carpels taken to- gether are called the gyncecium. Having these two words, car- pel and gyncecium, the word pistil is not really needed at ; It is a very com- monly used word, however, and it would be inconvenient to try to get along without it. Within the ovary the undeveloped seeds are found. They commonly resemble small pearls. They are called ovules. The ovules are attached to the sides of the ovary or to walls which sometimes divide the ovary into separate compartments. The number of such compartments indi-.
