Carrion flower Borneo and Sumatra. It can grow to be 3 feet across and weigh up to 15 pounds. "R. arnoldii" is a parasitic plant on "Tetrastigma" vine, which grows only in primary rainforests. It has no visible leaves, roots, or stem. It does not photosynthesize, but rather uses the host plant to obtain water and nutrients. Plants in the genus "Stapelia" are also called "carrion flowers". They are small, spineless, cactus-like succulent plants. Most species are native to South Africa, and are grown as potted plants elsewhere. The flowers of all species are hairy to varying degrees and generate the odor
Plant morphology al. 1983). Endogenous hormone levels are influenced by plant age, cold hardiness, dormancy, and other metabolic conditions; photoperiod, drought, temperature, and other external environmental conditions; and exogenous sources of PGRs, e.g., externally applied and of rhizospheric origin. Plants exhibit natural variation in their form and structure. While all organisms vary from individual to individual, plants exhibit an additional type of variation. Within a single individual, parts are repeated which may differ in form and structure from other similar parts. This variation is most easily seen in the leaves of a plant, though other organs such as stems and flowers may
