Description Inflorescence: The prominent feature of the inflorescence of Amorphophallus cirrifer is the hairy appendix on the spadix, resembling the appearance of a mouse. The color of the inflorescence is generally dark. In its native habitat of Thailand, where various mouse species, such as those from the Scandentia genus, are abundant, the spadix's hairy protrusion closely resemble the tails of these species. The peculiar evolution of this morphology is believed to provide advantages for survival. When in bloom, the scent is described as similar to sewage or rotting flesh. The evolution of the odor is thought to mimic that of a deceased mouse. The prosence of hair-like staminodes is shared with A.pilosus, A.lanuginosus and A.laoticus but in none of this species are hairs found on all parts of the spadix. Leaf: The leaflets are elliptical shape, and the pattern on the petiole consists of large circular spots in dark brown and light, dingy green. Tuber: The tuber is vertically elongated and has a bluish-blackish color. In the description provided when this species was announced, it was mentioned as being whitish, but due to the photos of the tuber on Alan Galloway's site showing blackish, there may have been some mistake or misunderstanding at the time of the announcement. The yellow tuber of Amorphophallus macrophyllus? that I am growing turned blackish when exposed to sunlight, so this may also be related to such phenomena. Fruit: The immature fruit is light green, but upon ripening, it turns white. Species producing white fruit are relatively rare within the genus.
