The second method is regeneration from caducous organs. Stipules varying in form, caducous. Young plants are wholly covered with long, caducous, brown or white hairs. The leaves are fleshy cylindrical, terminating in a persistent or caducous bristle. It is a perennial, evergreen or caducous sub-shrub. The scales are obovate, lobed, and fringed, membranous, hairy or smooth, and usually caducous. Their leaves are alternate, commonly palmately lobed, with small and caducous stipules. The petals when present are equal or unequal, often caducous during anthesis. The flowers are actinomorphic with two caducous sepals and five fugacious petals. The lost structures are said to be caducous. Caducous brown hairs are present on developing pitchers. Caducous hairs cover developing pitchers and other parts. Immature parts of the plant may bear a sparse indumentum of white, mostly caducous hairs. The three types of stipules according to duration are caducous, deciduous and persistent. On some species, however, they are small, inconspicuous, and caducous (soon falling).
