Leaf Observations

Specimen: One green leaf approximately 6.5 inches long. Has a elliptical shape with pointy ends. Has a serrated appearance on the edges. The width of where the stem was attached to the mother plant is about .25 inches across.
Interesting Features: There is a lighter green ribbon like structure across one vertical half of the leaf, on the right side. It almost appears as if someone drizzled the leaf with a lighter green paint. There appears to be two separate "tracks" of this lighter green. It looks to me like an insect was eating parts of the leaf and this is the track left by that. The tracks are minuscule in width. I would say they are 1/16 of an inch at most. I'd say one of them is about ten inches in length an the other is about 6. The ribbon like structures appear to be only on the surface of the leaf. On the back side of the leaf they are barely visible. On the left side of the leaf there is an odd shaped hole. There is a yellowing around the edge of this hole. It has the shape of a fidget spinner. There appear to be fine, hairlike structures on the stem of the leaf. The stem is more of a yellow green than the rest of the leaf. There are small almost shiny dots on the leaf that go away after it is washed.
The specimen is a serrated edged leaf. The leaf is approximately 155mm in length with an elliptical shape. One end has the base of the stem where the leaf was attached to the mother plant. The other end is pointed. At the widest part, the leaf measures about 50mm. The stem is about 5mm across. There appear to be 2 lighter green "tracks" on the leaf. They take on a drizzled appearance. Almost as if someone drizzled icing on the leaf. The widest part of these tracks measures approximately 2mm at the thinnest part the track measures less than .5mm. These tracks only appear on the right vertical half of the leaf. They only appear on the top surface of the leaf. The length of the tracks in total measure about 105mm and 145mm. On the left vertical half of the leaf there is an oddly shaped hole that has the shape of a fidget spinner. This hole has yellowing around the edges and is about 70mm up from the base of the stem.
