玫

Left-side jade radical — the left-position form of 玉, the dot omitted to fit the slot. It is the indexing radical for the gem family: 玉 jade, 珠 pearl, 珍 precious, 瑶 fine jade. In 玫 it names a kind of fine reddish jade, the original meaning before the character was repurposed inside 玫瑰 to spell 'rose'.

Right side 攵 supplies the sound — pū drifting to méi through an old labial m/p alternation. Visually identical to the rap radical, but here it plays a purely phonetic role: 玫 names a jade, not anything struck. The same phonetic shape appears in 政 government and 故 reason, both pronounced very differently.
