This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1906 edition. Excerpt: ...Corresponding to them in the plant world is an extraordinary variety of flower adaptations that can only be explained with reference to the regularly occurring cross-pollination effected by their visits. To this group belong: --1. Hymenoptera. Long-tongued bees (Apidae--Anthidium, Anthophora=Podalirius, Apis, Bombus, Ceratina, Chalicodoma=Megachile, Chelostoma = Eriades in part, Coelioxys, Crocisa, Diphysis=Trachusa, Eucera, Megachile, Melecta, Meliturga, Nomada, Osmia, Psithyrus, Saropoda = Podalirius in part, Systropha, Tetralonia==Eucera (Macrocera), Trypetes=Eriades in part, Xylocopa, and also Rophites). 2.

It consequently follows that flowers possess protective arrangements repelling their visits but no adaptations facilitating them. There have in particular been developed in flowers a series of structures serving to prevent the entry of these unbidden guests, which are mostly nectarthieves. Ants, which are described as dystropous by Loew, are not regarded as such by Verhoeff ('Bl. u. Ins. auf Norderney, ' p. 169), but Loew ('Bliitenbiol. Floristik, ' p. 387, note) calls attention to the fact that Hermann M filler in his 'Alpenblumen' also described ants as either valueless or harmful ( + ) for flowers, and of forty-three ant-visits he observed thirty-four were dystropous.
