trifoliolate

• “Baillon, [265] wherein the pistil of _Trifolium repens_ consisted of three carpels, either separate, or combined so as to form a one-celled ovary with three parietal, pluri-ovulate placentæ; the ovary in these flowers was formed of the basal vaginiform part of the leaf; the three styles were formed by the petioles, while the stigmas were represented by trifoliolate leaves.”

• “In some few instances the calyx is not at all altered, but the carpellary leaf is trifoliolate, or even quinquefoliolate, the corolla being then absent.”

• “Poison (trifoliolate, or _three-leaved_) ivy resembles Virginia Creeper, and all nurses and caretakers should be able to recognize it.”

  The Mother and Her Child

• “Next [351] to these come the fours and the sixes, while the trifoliolate and seven-bladed types are nearly equal in number.”

  Species and Varieties, Their Origin by Mutation

• “Only those parents that give [349] the highest percentage are chosen, and among their progeny only the seedlings with trifoliolate primary leaves are planted out.”

  Species and Varieties, Their Origin by Mutation

• “It had produced seven ascidia in all, each formed by the conversion of one leaflet on the trifoliolate leaves.”

  Species and Varieties, Their Origin by Mutation

• “The European pine or _Pinus sylvestris_ ordinarily has two needles in each sheath, but trifoliolate sheaths occur on the stems and stronger branches, where they prefer, as a rule, the upper parts of the single annual shoots.”

  Species and Varieties, Their Origin by Mutation

• “In summer the range is wider, and besides many trifoliolate leaves the curiously shaped seven-bladed ones are not at all rare.”

  Species and Varieties, Their Origin by Mutation

• “It is never quite free from the old atavistic type of the trifoliolate leaves, and invariably, when external conditions become less favorable, this atavistic form is apt to gain dominion over the more refined varietal character.”

  Species and Varieties, Their Origin by Mutation

• “They are most marked among leguminous plants, as shown by the trifoliolate leaves of the thorn-broom and allies, which in the adult state have green twigs destitute of leaves.”
