Cupressus 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 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.

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

- 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.

- 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.
