https://www.youtube.com/watch?v=FJMJQsGNdc0I found an asparagus plant in the yard, bearing a leaf with an imperfection. The leaf is a complex structure with green jungle-like regions of puffy green cells covered with a thin membrane and areas with gritty and irregular cells. There are the usual ribbons and rail-road track like pathways. The imperfection looks like kind of dark cloud that changes the color scheme. This is a perfect territory for a tour.
