UPPER MONROE ROAD; ridgetop hillock on the divide
between Persinger, Horse, and Little Dalton canyons; ca
850-930 m NW of Horse Canyon Saddle. Glendora 7.5'
USGS quadrangle; T2N R9W, SE/4 SW/4 SW/4 and
SW/4 SE/4 SW/4 section 34; elev ca 3360-3520 feet.
North side of hillock on mesic northerly and
northwesterly slopes draining to Persinger Canyon. Mesic
chaparral burned in May of 1992 by Forest Service
personnel in order to convert a broad swath into a weedy
firebreak. Formerly with Heteromeles arbutifolia,
Quercus wistizeni, Qu. berberidifolia, Cercocarpus
betuloides, Lonicera subspicata johnstonii, Lepechinia
fragrans, Keckiella cordifolia, Garrya veatchii, etc. I
wanted to document some of the fire-followers before the
area is completely converted to weeds.
Succulent annual, occasional on bum, forming
prostrate mats 20-50 cm across.
