Cleaning up in Kern County

I spent last Friday looking for some rare plants in the Southern Sierras with a fellow plant nerd. Out of our five target species, we managed a clean sweep!

Our first stop was at a pull-off on highway 178 in the lower Kern River Canyon. I’ve looked for rare plants here several times, but always came up short. This time, however, my luck changed. There, on a rocky cliff, a cluster of pink flowers! It was Delphinium purpusii (Rose-flowered Larkspur, Ranunculaceae). I’ve seen blue larkspurs, and purple ones, white larkspurs, and red, but this was my first pink Delphinium. This species, endemic to western Kern and Tulare Counties, is the only pink larkspur in North America. So of course I scrambled 50 feet up through thickets of poison oak to get a closer look!

 

Amazingly, this wasn’t the only rare plant of the stop. Hiding just blow the larkspur, was another very local endemic, Clarkia exilis (Slender Clarkia, Onagraceae).

Yes, its pink flowers are showy, but nevertheless it is tricky to pick out among its globally much more common, and much hairier cousin Clarkia unguiculata (Woodland Clarkia).

Our next stop was the granite gravel plains of Kelso Creek and surrounds. Here we ran into two plants that I met (and posted about) last year. However I managed to get better pictures this time around. Canbya candida (Pygmy Poppy, Papaveraceae)

and Mimulus shevockii (Kelso Creek Monkeyflower, Phrymaceae)

The former is found in scattered occurrences throught the western Mojave, while the latter is only found here. Both extremely small and extremely adorable annuals.

Finally, we headed into the Greehorn Mountains north of Lake Isabella, with one prize in mind. A short hike and a long search revealed exactly one flowering Fritillaria brandegeei (Greenhorn Mountains Fritillary, Liliaceae).

I’ve looked for this rarity about 5 times now, so it was sweet to finally track it down.

I had a very successful botanical hike this weekend, so I will post about that soon.
