The timing is still midsummer. Perhaps due to a few days of rain, many leaves have turned yellow and fallen, adding a new golden color to the park ground. It is not as dense as the fallen leaves in late autumn, sometimes sparsely and fallen a few pieces, set off on the sand, especially the perfect shape of the leaves.
  I picked up a leaf from the ground and wanted to store it in a sketchbook for memorizing. The leaves are oval, placed on the palm, just the size of the palm.
  The leaves on the tree grow up high and flutter and shine in the sun and wind. The gradation of colors and the brilliance of light make it difficult to find the perfect shape of a single leaf. The fallen leaves on the ground turned into a faint golden color, a little transparent, and placed in the palm, people can clearly observe the slender and complex texture of the veins, and a small leaf is so ingenious.
  Oval leaves with inconspicuous fine serrations on the edges. All the serrations are oriented in the same direction, extending from the upper end of the leaf stalk to the beautifully shaped leaf tip, which seems to be hand-cut by the best tailor.
  I asked the local residents resting in the park and they said it was a bodhi leaf. But unlike the bodhi leaves I saw, the bodhi leaves in my hometown are much larger, with a shape closer to the heart shape, with a broad top and narrow bottom, and the tip of the leaf is three or four times longer than the bodhi leaf here.
  A friend who studied botany gave me a more scientific answer. He said: “The leaf stalk is slender but very firm because it supports the weight of the whole leaf.” He added: “Many leaves have serrations on the edges. Defense motivation.”
  I was a little surprised at first. I admired the beautiful shape of a leaf. I wanted to sing a leaf with words. I wanted to express and record a leaf with color, line and texture. Friends of plants have different perspectives in the field of research.
  The Bodhi leaf in my hometown is indeed more like a heart shape, especially the elongated leaf tip, which makes people feel that it is a valve of the human heart that can feel meticulous thoughts.
  Regarding the slender leaf tip, my friends studying botany still have different explanations. He said: “The leaf tips of many plants are used for drainage. Especially in the tropics, a large number of sudden heavy rains accumulate on the leaves, which will cause the leaves to be injured and rot. Over time, the leaves of plants have evolved the function of quickly draining water. In fact, it is the result of the long-term evolution of function.”
  Therefore, I cherish the firmness of the leaf stalks. I cherish the leaf veins as finely distributed as human blood vessels. I cherish the serrated fine lines on the edge of the leaf like lace, and I cherish the fullness of a heart. , And with such a beautiful shape that can be held in the palm, I cherish the tip of the leaf that is as thin as a bird’s feather… Is it just the traces of the various difficulties of a leaf through the long years of survival?
  ”How long will it take to evolve into this shape?” I asked curiously. A friend who studied botany shrugged and replied: “A hundred million years.”
  My friend’s answer silenced me.
  Is beauty the last memory of life’s hard survival? Is beauty a bitter self-completion? So beauty makes me ecstatic and sad.
  I opened the sketchbook, and the blank paper was rubbed with traces of the leaf’s light wet stains, like a tear mark that is not easy to notice.
