Ranunculus is a large genus of annual or perennial, usual acrid, herbs with generally palmately divided leaves and solitary or cymose yeUow or white flowers. The generally five sepals are green and fall. Fig. 70. Ranunculus repens. A. Upper portion of stem, x |. B. Fruit, x H. C. Achene cut lengthwise, x 10; e, endosperm; c, cotyledons; r, radicle. (From Flor. Jam.) early, the five or more petals are generally larger than the sej^als and bear a nectary above the base. The numerous stamens are arranged in 13 row^s. The section Ficaria, represented in the British Isles by R. Ficaria (Lesser Celandine), has entire heart- shaped leaves, and generally three sepals and seven to eight (4-11) petals.^ The section Batrachium contains water- or marsh-plants 1 Salisbury, Annals of Botany, xxxm, 47 (1919), has recently studied the variation in number in the parts of the flower in this and other genera. He concludes that the flower of Ranunculaceae has been derived from a trimerous type, which has in many cases become obscured by multiplication of parts and consequent changes in phyllotaxy, or by fusion and abortion. He also supi^orts the view that the perianth or calyx is derived from the bracts and the petals from the staminal 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
