236 BOTANY OF THE LIVING PLANT by a non-functional staminode (Fig. 183), while in others of the family it may be absent. In Veronica the two anterior stamens are also abortive. The two posterior petals fuse so that the corolla appears to be four-lobed ; the posterior sepal, which is present in the Mullein, is represented in some species of Veronica by a sepal smaller than the rest ; in other species it is absent, as in Veronica chamaedrys and the most of the Rhinantheae. Thus the flower, though typically pentamerous, has by stages of meiomery

Fig. 184. Dissections of flowers of Lychnis dioica. I., II., VIII., the pistillate flower in which the stamens are represented only by staminodes (st). III., IV., IX., the pistillate flowers in which the gynoecium is represented only by a vestigium (gyn). i become apparently tetramerous. Similar changes occur in the Plantains and Teasels. Such examples serve to show that meiomer)^ by abortion may affect any of the series of parts, and not unfrequently more than one of them in the same flower. It is probably the cause of greater divergence of detail in flowers than any other factor. The most important cases are, however, those where one or other of the essential organs may be wholly abortive. It frequently occurs that flowers typically hermaphrodite may be staminate or pistillate, by 1
This large AI-assisted collection comprises about 60,000 images of botanical drawings and illustrations. It spans from the 14th to 19th century. As of today, we estimate the total number of botanical illustrations in our archive as 200,000 and growing. The "golden age" of botanical illustration is generally considered to be the 18th and 19th centuries, a time when there was a great deal of interest in botany and a proliferation of botanical illustrations being produced. During this period, many of the great botanical illustrators of the time, such as Maria Sybilla Merian, Pierre-Joseph Redouté, and John James Audubon, were active and produced some of the most iconic and influential botanical illustrations of all time. In addition to being used for scientific purposes, botanical illustrations were also highly prized for their beauty and were often used to decorate homes and other public spaces. Many of the most famous botanical illustrations from this period are still admired and collected today for their beauty and historical significance. All large Picryl collections were made possible with the development of neural image recognition. We made our best to reduce false-positive image recognition to under 5%.
