INFORMATION PROVIDED WITH THE PHOTO
  • date of photo  Apr 25, 2008
  • location   Off Kelbaker Rd., north of I-40, Granite Mountains area (San Bernardino County, California, US)
  • family Fabaceae
  • notes   Habit of a flowering specimen, with its beautiful deep purple-blue flowers and gray-green foliage. (Psorothammus also often have a subtle 'pastel-purple' hue infused in their otherwise bleached pale white bark, which is completely exposed in droughty periods when the plants drop their leaves.) There was no fruit, so I wasn't able to unequivocally separate P. arborescens from P. fremontii while keying this specimen in the field. Later, while pursuing this issue, I came upon an interesting article in Madrono (Vol. 52, No. 4, 2005, pp 258-261) by Dana York and J. Adams. They found that examining the glands on the fruit is crucial for distinguishing P. fremontii from P. arborescens, and that it's unlikely that P. fremontii occurs in California beyond a population in the Grapevine Mountains in Death Valley NP, very near Nevada. So, I'm going with P. arborescens here, and with var. minutifolius, since the calyces are only sparsely hairy (as opposed to conspicuously so...as seen in the CalPhotos posts of P. a. var. arborescens by Michelle Cloud-Hughes, for instance: http://calphotos.berkeley.edu/cgi/img_query?query_src=ucjeps&enlarge=0000+0000+0905+0802
