  CHSC98101  Symphoricarpos mollis LeRoy Gross; Michael Denslow, Bill Hogshead, S. Swartzentruber 2003-6-17 1067 Los Angeles Transverse Ranges; Verdugo Mountains region: North side of mountains: South of Hostetter Motorway (on the Thomas guide), just off La Tuna Canyon Road, south of and you can see the 210 freeway. Unnamed canyon that Hostetter road follows to near the main crest. Could be La Tuna Canyon as this is near the head of that canyon. If this is La Tuna Canyon, then the canyon makes a turn from draining to the west, turns south so the drainage is north. These collections are around the bend in the canyon. The canyon is narrower here and thick with brush, as the canyon is not very incised into the mountains. 550 Comment
