| Reviewer's comments: | | | | "ID and comments apply to whole Witham series. Trif. lilacinum is quite distinct from T. barbig. in morphology and DNA, but unjustly "lumped" with it at present. Extremely rare, known from only 2 other locations (Livermore and Pleasanton Ridge) plus one small colony of a different form at Cambria and apparently a newly discovered site N of Hwy 12 (see Akulova photo). There is also a genetically distinct f;orm I've been calling T. l. var. solano, which has smaller, white fls and leaf marks unlike T. l. s. str. I have found this several places in Solano Co. incl. Jepson Pr., but always as solitary plants rather than colonies. These and other clovers were reported to be abundant at JP before the cattle were removed, but now they hardly show up at all except on the road. One year a small area near the entrance was scraped bare and it came up solid with these clovers, but of course they disappeared again when the grass came back. Try scraping or plowing a few places around the reserve and you will be amazed how the native seedbank rebounds. I've seen it over and over. A little sheep-grazing is too little too late and too timid a strategy." |
