, but also a crop of fruit. Hence, if every ninth vinein the vineyard could thus be suddenly transformed from an indirectto a direct producer, the proceeds of the land might be increased elevenand one-tenth per cent. If it were possible to replace all of our fruit-bearing varieties withself-fertile vines, ideal conditions respective to pollination would pre-vail in the vineyard. Each pistil in the flower would be surrounded byan abundance of pollen, and pollination itself would become independentof insect activities. Hence the crops of fruit would become more regu-lar, irrespective of seasonal and climatic conditions, and the financialreturns might be increased correspondingly. *Reference to cited literature is made by number The BulletinII. Morphological Differences in the Flowers of VlTIS RoTUNDIFOLIA Grape flowers can be divided into three general classes or types: 1. The perfect hermaphrodite flower. 2.

Fig. 1.—Three different types of flower clusters and flowers; on the left, staminate; in themiddle, hermaphrodite with reflexed stamens; on the right, hermaphrodite with uprightstamens. Natural size. These types may be briefly described as follows: After the petals, or caps as the united petals of a grape flower arecalled, have fallen, the perfect hermaphrodite flower consists essentiallyof a normal pistil and five or more upright stamens. Each pistil isfunctional and under proper conditions is.capable of setting and develop-ing a normal fruit. The stamens are strong and healthy. The filamentsequal or exceed the combined length of the ovary, style, and stigma.They are stout and fairly symmetrically developed about their longi-tudinal axes. At the base of the ovary and between the stamens aresituated the nectar glands, which secrete nectar, attractive to insects. The staminate or male flowers are hermaphrodite flowers in whichthe pistils have been almost or wholly suppressed. It is a
