kind of plant
藶 refers to a specific kind of plant. Its meaning is narrow and botanical, without a broader conceptual center.
藶 combines the grass radical 艹 with 歷, which likely contributes the sound. The character is used in plant names, but the exact historical development is uncertain.
The grass radical 艹 sits above 歷, like a plant growing over a historical record. Picture a specific plant species named after its discoverer's journey.
For レキ, imagine a plant called 'reki' that grows in a rocky crevice: reki -> レキ, and the grass top 艹 marks it as a plant.
