veinlet
Leaf's fine line
A veinlet is a small vein, especially in geology or botany.
In rock formations, veinlets are thin mineral deposits threading through host stone—narrower than proper veins.
In leaves, veinlets are the finest branches of the vascular network, visible as delicate lines beneath the surface.
