Checklist for Villager Peak Trail and Rattlesnake Canyon

See:

• Notes on the Scientific Names Used At This Site and
• Information about the links from the Scientific Name and Common Name.

An asterisk before the common name indicates a non-native species.

The column with header Famil gives the first five letters of the Family Name.

The column with header RS gives the minimum number of plants seen in Rattlesnake Canyon above the Villager Peak Trail, up to a maximum of 99 plants. Most of these plants are in the first 2.3 miles of Rattlesnake Canyon. If that column contains iNat, there is an iNaturalist observation of that species that we have not yet seen. The V in that column indicates the single species vouchered at Rattlesnake Spring not seen by us.

The column with label VP gives the minimum number of plants found in the area of the Villager Peak Trail, up to a maximum of 99 plants.
