Brief Introduction to this Checklist

See Flora of Southern California: Master Checklist for a more complete Introduction to this page.

The plants in this list are found on pages 109 to 134 in the printed JM2, with additional species found only in the online JM2 manual. See the notes below.

Click on the Scientific Name to get the JM2 online entry for each taxon, which includes:

Some links to the JM2 online entry will return no JM2 online entry, since hybrids, and the taxa mentioned as judgment-reserved taxa, are not yet entered into the JM2 name index. Those links may work in the future.

Click on the Common Name to get the Calphotos pictures. Since some taxa have no photos at Calphotos, those links will return no pictures. Be aware that the names in Calphotos are not synonymized, which means that if the name has changed in the JM2, all the Calphotos may still be under the JM1 name, and will not be retrieved by this link.

The column with header #Obs gives the number of observations in my database of each taxon from plant trail guides and floras that I've done.

The column #Lists gives the number of checklists that I've digitized that contain each taxon.

See Flora of Southern California: Master Checklist for some of the biases in those numbers.

Notes on Some Taxa

The taxa with notes are given in alphabetical order here.

Cheilanthes covillei X C. parryi. This is a rare F1 hybrid between the two species, and has been given the name C. xparishii, mentioned in the JM2 treatment for C. covillei.

Cheilanthes intertexta. Not given as a southern California taxa in JM1 or JM2, but there are now nine vouchers at the Consortium for southern California, from SnBr near Lake Arrowhead; from Andreas Canyon near Palm Springs; and from Cuyamaca Peak in the Cuyamaca / Laguna Mountains. One voucher was determined by Steve Boyd; another by Jon Rebman, both quite knowledgeable about fern species.

However, one of those vouchers was determined by Munz as C. intertexta in 1922, yet Munz did not place this species in southern California in his 1974 Flora of Southern California.

I personally know nothing about C. intertexta, but in the JM2 key it seems extremely close to C. clevelandii, a very common species in southern California:

5. 2-colored rhizome scales with well-defined, dark mid-stripe and light brown margins 1/2 to = width of mid-stripe; leaf gray-green, segments round to cordate ..... C. clevelandii

5'. 2-colored rhizome scales with well-defined, dark mid-stripe and light brown margins much narrower than mid-stripe; leaf dark green, segments round ..... C. intertexta

As a result, it wouldn't be terribly surprising if a very small number of C. clevelandii plants had characteristics closer to those in the key for C. intertexta.

It would be interesting to know if the JM2 author knew about these vouchers and rejected this determination, or if the JM2 author was unaware of these vouchers.

Pentagramma triangularis ssp. maxonii. This taxon is marked as having a change, but the change was not in its name. What has changed are voucher determinations. Many vouchers formerly determined as ssp. viscosa in southwest San Diego County have now been redetermined as ssp. maxonii.

Polypodium scouleri. Given as being in SCo, n ChI in the JM2, with this note: Pls called P.s. from n ChI are fertile or sterile hybrids involving P. californicum. SCo was added to its geographic range in JM2. It would be interesting to know if those plants are also hybrids.
