Select a flower of each kind, and examine first the one with the protuberance (Fig. 61), which latter, from its appearance, you will prob- ably have rightly guessed to be the ovary. The situation of the ovary here, indeed, is the same as in the Willow-herb. The Fig. ei. calyx-tube adheres to its surface, and is prolonged to some little distance above it, expanding finally into five teeth. The corolla is gamopetalous, and is adherent to the calyx. Remove now the calyx and the adherent corolla, and there is left in the centre of the flower a short column, terminating in three stigmas, each two- lobed. There are no stamens, 53. Now examine the other blossom (Fig. 62). Calyx and corolla have almost exactly the same appearance as before. Remove them, and you have left three stamens grow- ing on the calyx-tube, and slightly united by their anthers Fig. 62. (syngenesious). There is no pistil. You see now why some blossoms produce cucumbers, and others do not. Alost of the have no pistil, and are termed staminate or sterile flowers, whilst the others are pistillate or fertile.
