Two abbreviations you may find handy:
SPF - Spruce/Pine/Fir. This lumber is what all the hubbub is about.
It is lumber from one of eight species of trees: Red Spruce, Black Spruce, White Spruce, Engelmann Spruce, Jack Pine, Lodgepole Pine, Balsam Fir, and Alpine Fir Most of it comes from Canada, but its range extends to about the California-Oregon state line. This is a soft timber--you can press your fingernail into it--with good fiber strength. It's mostly white in color.
SYP - Southern Yellow Pine. It comes from four species: Loblolly Pine, Longleaf Pine, Shortleaf Pine, and Slash Pine. This wood is, as its name suggests, yellow in color. It has excellent fiber strength and it's hard as a rock--the slow-growth rings (the dark ones) are harder than walnut, which is very hard. These species only grow in an area bounded by Texas on the West and Virginia to the North, all the way to the eastern and southern shores.

Amelia Lumber makes borate-treated lumber. This is a very insect-resistant product used primarily as framing lumber and for windowframes because the borate leaches out of the lumber if it gets wet. In the US, borate-treatment is applied primarily to two species groups: Southern Yellow Pine and Radiata Pine.A.V. Littrell Lumber Mill, Tishomingo, Mississippi
