[8] Leaves The leaves of the plant sometimes have very fine and soft hairs on the upper surface, although the plant is mostly hairless. There is no leaf stalk; leaves grow immediately from the stems.
Odor intensity can be expressed using an odor intensity scale, which is a verbal description of an odor sensation to which a numerical value is assigned. [31] Odor intensity can be divided into the following categories according to intensity: 0 – no odor 1 – very weak (odor threshold) 2 – weak 3 – distinct 4 – strong 5 – very strong

This plant has a mechanism to heat up the spadix enhancing the emission of the strong odor to attract its pollinators, carrion-eating beetles and "flesh flies" (family Sarcophagidae). It was first described scientifically in 1878 in Sumatra. [1] Flower of Rafflesia kerrii, in Khao Sok National Park, Southern Thailand.
The strong odor emitted by many plants consists of green leaf volatiles, a subset of VOCs. Although intended for nearby organisms to detect and respond to, these volatiles can be detected and communicated through wireless electronic transmission, by embedding nanosensors and infrared transmitters into the plant materials themselves.
