Historical forms of the character 瓣
Shuowen Jiezi (compiled in Han)	Liushutong (compiled in Ming)
Small seal script	Transcribed ancient scripts

Phono-semantic compound (形聲／形声, OC *breːns) : phonetic 辡 (OC *prenʔ, *brenʔ) + semantic 瓜 (“melon”). However, the phonetic component (the reduplication of the knife to mark prisoners) perhaps symbolizes two prisoners accusing each other, which then leads to the concept of "discrimination, differentiation" and finally to the concept of "part, segment, what is differentiated", originally referred to melon seeds.

"segment, section, piece"

Exopassive of 辨 (OC *brenʔ, “to divide, distinguish, discriminate”); possibly in the same word-family as another exopassive 釆 (“[to cause to be] divided”). These three thus may be related to either 班 (OC *praːn, “to distribute → to arrange, classify → class, group”) or Mizo pʰel (“to split, cut in halves”) (with medial *-r- dropped after labial initials according to Mizo phonotactics) (Schuessler, 2007).

"petal"

Either same etymon as "segment, section, piece"; or same etymon as *葩 (OC *pʰraː, “flower”); or related to 燔 (OC *ban, “to burn”), if so, semantically parallel to Tibetan མེ་ཏོག (me tog, “flower”), literally "fire-top".
