Pine ID (pics)

Hello!

I was out hiking the other day, and I came across quite a few of these pines.
They were growing on the downslope below a canal, but I've seen them elsewhere in the area, as well.
Could they be a variety of P. ponderosa? The color is different and the needles are much shorter
than P. ponderosa, of course. I'm curious about this pine because I found a broom of this type
on a friend's property and I need to know which understock would be appropriate to use.

On with the pics.....

The juvenile bark is grey-silver and smooth, and the new shoots are somewhat yellowy.

In this pic, you have two unidentified pines to the right, then a P. ponderosa sapling to the left,
along with a Pseudotsuga menziesii in the back right.

Dang! Edit....

Sorry, that should be the back "left" (not right) for the Doug Fir sapling.

Pinus albicaulis perhaps? Just a guess.

Sugar pine, P. lambertiana.

Looks like lambertiana to me.

Hey, thanks! Sugar Pine makes perfect sense.

Come to this a bit late; agree Sugar Pine, but Western White Pine P. monticola can be similar - it usually has longer needles with more obvious white stomatal bands on the needle inner faces, but stunted specimens can be tricky.

Western white pine can be a look-alike for sugar pine, especially when small trees are involved. However, presence of Douglas-fir and what appear to be evergreen oaks, pretty well rule out the higher-elevation white pine in favor of sugar pine. White pines are likely on snow-covered ground, even though snow has been scarce this year.

The "Ponderosa" looks like a Jeffrey pine to me, but a closer view is needed.

Recently I saw what appeared to be sugar pine growing with Jeffrey pine in the Siskiyou-Klamath region.

Ponderosa and Jeffrey Pine do look similar ;-)

This is down around 2,000 feet elevation.
I'm more accustomed to seeing Jeffrey Pine at higher elevations.
Ponderosa is the predominant pine in the area, all of them with very long needles like those pictured.
What do you need to see? Number of needles? I can take pics this weekend.

I also have a couple Jeffrey Pine seedlings growing.

A 'scratch and sniff' test would be better:

Turpentine scent: Ponderosa
Lemony scent: Jeffrey

I'm stuffed up with a bad cold....but I think I should be able to smell the difference.
Thanks, Resin. I'll report back.

Jeffrey pine tends to be a different, bluer shade of green and with pinkish or bloomy shoots.

RE: Pine ID (pics)

I agree, Ron.
My Jeffrey seedlings have that bluish new growth color, similar to the color of Stone Pine.
The Ponderosa seedlings in this area tend to be more yellowy, chlorotic looking.
