Botany. 36 A TKXT-BOOK OF BOTANY bog plant (Fig. 34), but is not so elaborately constructed for capturing insects as is a common southern Sarra- cenia (Fig. 35). In this plant the leaves are slender, hol- low cones, and in a tuft from the swampy ground. The mouth of this conical urn is overarched and shaded by a hood, in which are translucent spots, like numerous small windows. Around the mouth of the urn are glands which secrete a sweet liq- I uid, known as nectar. Inside, just below the rim of the urn, is a glazed zone, so smooth that insects cannot walk upon it. Below the glazed zone is another one thickly set with stiff, down ward-pointing hairs; and below this is the liquid in the bottom of the urn. If a Hy, attracted to the nectar at the rim of the urn, attempts to descend within the urn, it slips on the glazed zone and falls into the water; and if it attempts to escape by crawling, the downward-point- ing hairs prevent. If it seeks to fly from the rim, it naturally flies toward the translucent spots in the hood, since the direction of en- trance is in the shadow; and pounding against the Fig. 33.—Lea\es ul barberij' develnping un 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 may not perfectly resemble the original Coulter, John Merle, 1851-1928.
