Pinguicula

Post by sujin007 on Fri Nov 23, 2012 7:39 pm

Pinguicula, or butterworts, are a group of carnivorous plants that use sticky, glandular leaves to lure, trap and digest insects. The nutrients from the insects supplement the poor mineral content of the soil.

There are roughly 80 species that can be found throughout North and South America, Europe and Asia. The leaves of the butterwort are succulent and usually bright green or pinkish in color.

There are two special types of cells found on the top side of the butterwort leaves. One is known as a penduncular gland, and consists of secretory cells on top of a single stalk cell.

These cells produce a mucilaginous secretion which forms visible droplets across the leaves surface, and acts like flypaper.

The other cells are called sessile glands. They lie flat on the leaves surface and produce enzymes like amylase, esterase and protease, which aid in the digesting process.

Where some butterwort species are carnivorous all year round, many types form a tight winter rosette, which is not carnivorous. When summer comes, it brings with it new blooms and a new set of carnivorous leaves.
