PITCHER-PLANT FAMILY (Sarraceniaceae)

[Illustration: YELLOW PITCHER-PLANT]

Herbs with tubular leaves; flowers nodding; sepals 4-5; petals 5, or

absent; stamens numerous; style often umbrella-like; ovary 3-5-celled.

Yellow Pitcher-Plant. Trumpet-Leaf (_Sarracenia sledgei_) is also called

trumpets, water-cup, watches, and biscuits. The last two names are

suggestive of the broad, umbrella-shaped structure bearing the stigmas

and occupying the center of the flower. The other names refer to the

tubular, ribbed, trumpet-shaped leaves. The flowers are drooping at

maturity, with 5 fiddle-shaped yellow petals and 5 shorter yellow sepals

tinged with brown or red. It grows in swamps from East Texas to Alabama

and is quite similar to the eastern _Sarracenia flava_. April-May.

The pitcher-plant is a most efficient collector of insects. The upper

part of the leaf bends over, forming a lid whose inner surface is

covered with minute honey-glands attractive to insects. The upper part

of the tube is smooth, affording little foothold and causing the insect

to fall into and drown in the sticky fluid given off in the lower part

of the tube. Downwardly directed hairs prevent his escape. After a time

his body is dissolved and absorbed by the plant. An overdose of animal

food causes the browning and decay of the leaves.
