Plant Communities and Floristics

This section is not updated every time the guide is updated. Last update for this section: 27 February 2004. (Only the histogram in the Number of Unique Taxa On This Trail is always updated each time the guide is updated.)
See Plant Communities and Floristics for the Beach Trail.
The Trail plant list contains 96 taxa, of which 90 have so far been identified, in 0.87 unique miles of trail. One additional taxon has not been identified to species, but it is a non-native iceplant. Of these 91 taxa, 14 (15%) are non-native.
I have plotted these numbers against the other trails in my database. The plots show:

For its elevation, the percentage of native taxa is surprisingly high compared to the other trails in our database. This is most likely due to the relative pristineness of this area, but the incompleteness of this trail guide so far could also be a factor. The subnormal rainfall in the years I've surveyed this trail might not have germinated all the non-native annuals.
The number of native taxa is about that expected from our other trails.

Number of Unique Taxa On This Trail

The following histogram gives the number of trails in my database that contain each taxon on this trail. I had 73 trails in my database when this histogram was made; 2 of those trails, including this one, are at Torrey Pines. A number of "1" means the taxon has only been found on this trail among the trails in my database; numbers of "2" or smaller may indicate taxa found only at Torrey Pines.

I found 6 additional species not in the above table, since they have not been identified yet. The unidentified ones are marked with ? or sp in the id? column in the guide, and have no entries in the #all column.
The taxa that are truly unique, or almost unique, to this trail or area, out of the 73 trails in my database on 7 February 2004, are:

I thank James Dillane for help with the 11/29/03 fieldwork, especially for correcting one error in the guide and for supplying the names of other species found on this trail that were not visible in June or November.
I thank Jane Strong for help with the 2/5/04 fieldwork, for helping to find and identify new species on the trail, as well as verifying the species in the guide.
I thank a docent at Torrey Pines, who wishes to remain anonymous, for her help with the 1/13/05 fieldwork for the first 0.2 miles.

Comments On Specific Species

Lessingia filaginifolia var. filaginifolia. The Jepson Manual combined two taxa that are found at Torrey Pines, Corethrogyne filaginifolia varieties linifolia and virgata. The editors at the Jepson Online Interchange have restored the Corethrogyne treatment, but have still dispensed with the varieties.
Because the var. linifolia is strikingly different from the usual var. seen in Southern California, var. virgata, I attempted to note which of the varieties is found on the nearby Beach Trail. However, when I attempted to use the key in Munz to key a plant to variety, it turned out to have characteristics of both varieties. Perhaps this is why the Jepson Manual dispensed with the varieties!
Crassula connata and C. tillaea. In the same location, Jane Strong found C. connata on 2/5/04 and I found C. tillaea 6 weeks later on 3/18/04! I verified C. connata on 1/13/05 and will try to verify C. tillaea in the future.
Cardamine californica. I studied the plants on this trail intensively on 1/13/05, and they do not fit either subspecies. Using the characteristics in the Jepson Manual, I found roughly as many plants that could be called var. californica as could be called var. integrifolia, with most plants not fitting either variety.
At the first location on this trail, I counted 23 oblong, ~entire to 2-toothed leaflets (var. integrifolia); and 26 ovate, mostly-toothed leaflets var. californica. In many cases, an individual plant had both kinds of leaves on it. Typically, the lowermost 1-2 cauline leaves would be ovate and toothed; the uppermost 1-2 cauline leaves would be oblong and ~entire, usually only with a terminal tooth. The leaves were intermediate between thin and thick. If one felt the blade as a whole, they were thickish, primarily due to the midvein. If one felt only the parts of the blade away from the midvein, they were thinnish. I surveyed leaves through the trail, finding the same results.
Note that var. integrifolia in the Jepson Manual is much changed from what it was in Munz. Using the Munz key, all these plants are var. californica, as were all Southern California plants in Munz. In the JM, integrifolia is now supposedly in Southern California, and there are vouchers determined as var. integrifolia in San Diego County.
I'll pay attention to milkmaids in other areas of Southern California, to see if any differ from these plants.
Chaenactis glabriuscula var. orcuttiana. The identification is from plants at mile 0.48 in 2002.
Isocoma menziesii. In my experience, the subspecies are not separable in Southern California. See Comments on the Jepson Manual and A Flora of Southern California by Munz: Isocoma menziesii.
Abronia umbellata ssp. umbellata. The first occurrence on the trail was a baby plant on 1/13/05; a definite identification was at mile 0.32.
Erysimum capitatum ssp. capitatum?. These plants are definitely wallflowers. The identification is uncertain because E. ammophilum also is supposed to occur here. I haven't yet checked the immature fruit for the id.
Carpobrotus chilensis. This specimen was weeded out on 3/l8/04.
