The California Pitcher Plant Darlingtonia California Torr

BOTANICAL NAME Darlingtonia californica Torr. Unacceptable synonym Chrysamphora californica. F amily Sarraceniaceae. COMMON NAMES California pitcher plant, cobra plant, cobra lily. RANGE Pacific coastal bogs and mountain slopes from Oregon to northern California. Altitude varies from sea level to 2800 m. DESCRIPTION. Darlingtonia has mainly erect to sometimes decumbent tubular pitcher leaves which grow up to 90 cm, the semidecumbent leaves tending to be smaller. The pitcher leaves are narrow at...

The Future Of Carnivorous Plants

This section title propounds a vital question to which we can offer only some guesses, but they are largely well-founded guesses. Unfortunately, the outlook appears quite grim for many species. A number of factors contribute to this opinion. Primarily, the most dangerous hazards are the result of man's modification of the environment for personal and often shortsighted ends. These modifications include, particularly, the control of fire and water levels in wetlands. We will first consider the...

Growing North American Carnivorous Plants

Most of the carnivorous plants that have been discussed are not too difficult to grow successfully, given a few basic but rather strict requirements. There is clearly an increased interest in things botanical today, and there is special horticultural interest in unusual plants. Carnivorous plants now appear frequently in general houseplant catalogues, on the shelves of nurseries and commercial greenhouses, and in local discount and grocery stores. The number of dealers specializing in...

Kinds Of Traps

The traps of carnivorous plants are modified leaves that in some cases are so changed and adapted to their function that they resemble only remotely leaves as most people picture them. For example, the tall, often decorative tubular pitcher leaves of species of Sarracenia are frequently thought by the uninitiated to be flowers, and in most cases the trap leaves are far more striking than the plants' true flowers. This case of mistaken identity is somewhat ironic since it is accepted that most...

Carnivorous Plants Around The Continent

We have noted that carnivorous plants occur mainly in acid, freshwater wetlands. As is the case with all generalizations, this one has an exception or two. Drosophyllum luscitanicum, a native of Portugal and parts of Morocco, which will therefore not concern us further in this volume, occurs in semiarid regions. Of concern to us is a pitcher plant, Sarracenia purpurea, which can occasionally be found in alkaline marl bogs of the northeast as well as in its usual home in acid bogs. Now we are...

Info

The arms are divided at the ends, where they frequently bear traps. These floats support the flowering part of the scape out of the water, while the lower part of the scape is below water level and continuous with the vegetative portion of the plant deeper in the water. The flowers number from three to seven on the average, but there can be up to fourteen in U. inflata. While there are several differences between these very similar species some botanists would still consider radiata...
