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. 1909 edition. Excerpt: ...since been separated by Richard, the French botanist, on account of important differences in structure. Eptpactis is much more plentiful and more widely distributed than Cephalanlhera, occurring in woods and shady places throughout the kingdom, with the exception of the extreme north of Scotland. It has a creeping rootstock, and a solitary tall (3 feet) leafy stem; the lower leaves eggshaped, the upper ones narrower and smaller, all of them ribbed. The flowers form a one-sided raceme, with green bracts mostly larger than the flowers. They vary in colour from greenish with white, yellow, or purple markings, to a dull reddish-brown. In Cephalanthera and other genera of orchids, the ovary is twisted in order to bring the lip (which is properly the uppermost petal) to the lowest position on the flower. In Epipaciis the ovary is quite straight, but the same result is attained by the twisting of the footstalk. Then it will be noted that there is no prolongation of the lip into a spurred nectary behind: the reason for this lies in the fact that the flower is not fertilized by bees or other long tongued insects, but by wasps. To suit their particular shape of head and shortness of tongue, the lip is hollowed out behind to form a shallow bag, in which the nectar is secreted. The pollen-masses differ slightly from those of Cephalanthera, but are similarly placed to ensure their sticking to an insect that comes for honey. A wasp could enter this flower and take its fill of honey without disturbing the pollenmasses, but it cannot crawl out without striking against and detaching them, carrying them off to fertilize the next flower visited. So glutinous are the pollen grains that they cannot separate from one another and fall; and even if they could they would...show more
