Nearly all our cultivated fruits are of this class.

Dioecious, when the male flowers are on one plant, and the female on another. A familiar in- stance, among cultivated plants, is the hop. The straicberry is not truly dioe- cious, but in many varieties we find the stamens or male organs so incompletely m»ki lP~ '•''evelo])ed (), that they are of no ^^kw service in fructifying the flowers. Such varieties are termed pistillate, and we l>lant near them varieties with an abund- ance of tliese organs, strongly developed, as in fig. 39. 3d. Impregnation.—The pi-oceas of impregnation is effected in this way: When the flowers first open, the pollen granules are contained within the anther. In a short time, afler the flow- er opens, tlie anther bursts, usually by a longitudinal slit, and sometimes by other kinds of opening, and the pollen is let fall upon the stigma, or is carried to it by means of the insects that fre- quent the flowers in search of pollen and honey. The stigma is furnished with a glutinous, or sticky secretion, to which the pollen adheres ; there it prolongs a minute tube, which penetrates through the st jde of the pistil to the ovary, where it reaches the ovule, and imjn-egnation takes place; new cells are formed within the ovule, which results in the production of an embryo Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resem
