Looks like a Japanese winterberry (Ilex serrata). My apologies for the chopped off pot; our scanner is too small to accommodate the whole bonsai.
2016 starts tomorrow, so you’ll need a good calendar. Both the photos shown here are from our 2016 Bonsai Calendar. Our scanner is too small to fit whole pages, but I suspect these photos are enough to provoke your interest.
If you’ve been paying attention, you’ve noticed the recent evolution of the art of bonsai. It’s a world wide phenomenon and it’s moving very fast. I’ll blame the web among other things; including a surprising youth movement (lots of 20 and 30 somethings have been apprenticing in Japan, for example) and who knows what else? You can look for this trend to continue in 2016.
This one looks like a Japanese white pine (Pinus parviflora). I like the rough texture, the strange angles, the hollowed trunk, the pot, everything about it.
