What you're showing there are the taxa. It's really not possible to
lump one as perennials or woodyplants until you get down to the genus
or family level.

Yes, pines are gymnosperms, so they're in the Coniferophyta division (or
Pinophyta, depending on your taxonomist of choice :) Within Pinophyta,
there are lots of classes and orders (and subdivisions, too). For
example, the common yew might be found in
Coniferophyta:Pinopsida:Taxaceae:Taxus_x_media
but a cycad like Cycas revoluta would be in
Coniferophyta:Cycadopsida:Cycadaceae:Cycas_revoluta
Two problems that I've always had with maps like this are:
1. It's very hard to find things unless you know the scientific name of
the plant or its parentage
2. Which standard do you use? You say Coniferophyta, I say Pinophyta.
I also say that Ginkgo biloba falls under Pinophyta, but the map
online says that it falls under Ginkgophyta, One can strictly
adhere to the updates at the International Botanical Congresses,
but most don't.
For the most part, I use Dr. Arthur Cronquist's classification system
outlined in his 1992 work, "An Integrated System of Classification of
Flowering Plants." Beware -- this book is 1262 pages and costs
$225.00. A cheaper alternative is "Vascular Plant Taxonomy" by
Walters & Keil, which runs about $60.00:

I'm not aware of any online references.
> Does anyone have a picture of Pinus bungeana?
Here's a site that I'm working on, but it's not finished yet. There
are 20 photos of various Pinus bungeana characteristics there.
