quad data info
- Quad numbers in parentheses are from the CA Department of Water
Resources. The 7-digit numbers
are the USGS equivalent.
- Red marks signify uncertainty[?] or extirpation[*].
See quad list above. A complete key is
on the Index by Topo Quad page.
- Marks are smaller than the quads they represent, and are generally positioned
near the center of the quad. In some coastal quads, this will place the mark
offshore.
Quad boundaries do not coincide with county
lines. To confirm county location, refer to the county list below.

| blooming period
| Apr-Jun |
| elevation range | 5 - 150 meters |
| notes
| | Known from fewer than twenty occurrences. Threatened by grazing and insect predation, and potentially by road construction and development. Some inland plants weakly separated from var. occidentale. Compact, low-growing plants from MNT Co. (344C) are probably not var. compactum. |
