Orchid Family. This large and most at-' Apteria tractive group includes the most highly specialized of the monoco- tyledonous plants. The carefully conducted researches of Darwin and other scientists have demonstrated that the marvelous complexity of floral structure exhibited by the^ orchids is the result of special adap- tation or modification to secure fer- tilization through insect agency, and often through the visits of some par- ticular species of insect. Orchids are perennial herbs, with great diversity of habit. It may be stated as a general rule that those growing in temperate climates are terrestrial like most other plants, while those that are natives of warm or tropical regions are epiphytic, like the Bromeliads which were dis- cussed in a recent chapter (see sup- plement, page 41). The roots of ter- restrial species are usually thickened fig. 54.—siiowyOrohis(0»'(!fti««pec<a6«i«) nnd tnhpirnns somfiti'infis ftvon hnl showing parts of flower.
