Cupressus arizonica revealiana
- Tree
Broad rounded crown of old tree in Caņada Rincon. Unfortunately there are
no large old trees in the Cuyamaca stand to compare with. The crown is
completely different from the pyramidal crown and green foliage of Cupressus
montana, and it also grows in a very different climate, and much lower
elevation. Mesa Huicual, where many smaller trees are said to exist can be
seen to the left of the tree.

Cupressus arizonica revealiana - stephensonii
- Young tree comparison
The color of the foliage and form of young trees also differs considerable.
The Cuyamaca trees have darker, greener foliage, and long branches forming a
more open, irregular crown. The Rincon trees have bluer foliage and a dense
bushy crown, in some ways looking more similar to Cupressus glabra.

The Cuyamaca tree is the oldest remaining
tree. The difference between the bark colors is very obvious.

Cupressus arizonica revealiana - stephensonii
- First year cones comparison
Several interesting differences where noted between Cuyamaca population and
those of Rincon.
One of the most striking was in the color of the first year cones. Of
hundreds of trees I observed before the fire at Cuyamaca, none had the blue
cones we observed in the Rincon trees. The Cuyamaca trees all have brown
first year cones. The two photos below where both taken in late July.
Current DNA studies suggest that the Rincon population is different species.
Recent studies by Bartel (2003) suggest the Rincon trees are Cupressus
montana, which I do not agree with, but they are very distinct from the
Cuyamaca trees.

Cupressus arizonica revealiana - stephensonii
- Cones comparison
Another difference we noted is that the Cuyamaca Peak stand usually has cones
in dense clusters, on short stems, where the Rincon trees had cones with
long stems, generally hanging from the branch similar to Cupressus bakeri, not in
large clusters.
