b is the intercept constant (0.5 by definition). [31] 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 ...
The genus name is derived from the Greek words krokos, meaning "saffron", and osme, meaning "odour" – from the dried leaves emitting a strong smell like that of saffron (a spice derived from Crocus – another genus belonging to the Iridaceae) when immersed in hot water. [6]
The word funk initially referred (and still refers) to a strong odor. It is originally derived from Latin fumigare (which means "to smoke") via Old French fungiere and, in this sense, it was first documented in English in 1620.

[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.

Since odor detection may be an indicator that exposure to certain chemicals is occurring, olfactory fatigue can also reduce one's awareness about chemical hazard exposure. Olfactory fatigue is an example of neural adaptation. The body becomes desensitized to stimuli to prevent the overloading of the nervous system, thus allowing it to respond ...
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.
Hyperosmia is an increased olfactory acuity (heightened sense of smell), usually caused by a lower threshold for odor. [1] This perceptual disorder arises when there is an abnormally increased signal at any point between the olfactory receptors and the olfactory cortex.
