A flower that has an「emerging shaft」in the shape of an「adult man」or in other words, a flowering plant with a stamen (the「male organ」of a flower) that, in particular, resembles an erect penis, the male organ of a human: the HIBISCUS.
　Association with a LOTUS is perhaps due to the shape of an unopened lotus bud (that strongly resembles the shape of the human male's glans penis), especially, if the blossom is pinkish. LOTUS flowers also apparently contain a relatively high concentration of a phosphodiesterase inhibitor (active ingredient of Viagra®), and apomorphine that is also used to tread erectile dysfunction, which also may account for the association of the flower with an erect penis…the ancient Chinese sages knew quite a bit about herbal medicine. Moreover, LOTUS plant tubers only grow in deep muck slurry, not dry soil, another reference to where the male placed his erect penis whenever the chance reared its ugly red eye.
　「Emerging shaft of adult male human」seemingly also represents MT. FUJI, noting that in Japan this mountain is normally represented today by 富士, meaning literally「pussy completely surrounding and filled, with penis」as perhaps a reference to the shape of the mountain, or「abundant penis」perhaps as a reference to its eruption discharge pattern. Some say the mountain resembles a woman's breast as Japan's 'mother.' In any case, it is employed as a symbol of the virility of the nation of Japan, male or female or androgynous hermaphroditic. Scholars unanimously agree that it is most likely all the various glyphs were assigned to name the mountain in order to match the pronunciation of「fu-ji」since the mountain existed and was named by the Japanese prior to Chinese glyphs being used in Japan, and that no one truly knows why the mountain is called「fu-ji」otherwise…most sources will explain that the glyphs were used for pronunciation only (ateji) and that the glyph meanings are totally unrelated, but these same sources do not explain why all the various glyphs that have been used throughout history in poetry, stories, and for naming the mountain all have one thing in common: something to do with an erection, ejaculation, and the sexual organs.
　Interestingly, HIBISCUS is derived from Latin, and that from the Greek hibiskos meaning「marsh mallow」(a type of plant with a hollow stem shaft filled with sticky, whitish, creamy schmutz):「Ancient Egyptians were the first to enjoy a gooey treat now called marshmallow as early as 2000 BC. The treat was considered very special and it was reserved for gods and royalty. Marshmallow was made from the mallow plant (Athaea officinalis) that grows wild in marshes. …The Egyptians squeezed sap from the mallow plant and mixed it with nuts and honey.」(…sounds familiar…).
