You might have seen the TWIGS post from last week that showed the two-lead-bud pattern of the Striped Maple (or Moosewood) that grows along the creeks.
Just two days later, this is what became of that tiny compressed and highly-ordered bit of biology packed inside those bud scales. The rate of expansion from the micro- to the macroscopic is impressive. Wonder what it would like like in time-lapse video?
The deeply-veined deeply-lobed finely-toothed leaves are one of my favorite spring patterns early on as the leaves emerge translucent, in shades of yellow and chartreuse.
