The flowers were most definitely bright yellow, not white or pale yellow. It had a terminal leaf at the end of each set of leaflets and no thorns that I could see. The plant was a multi-stemmed shrub, maybe 8 feet tall, growing in an area with 0 irrigation, in sand on the edge of a stone cliff and against a brick retaining wall facing south. It was close to a small pistachio grove.
New location. Zone 6b, acid soil, 30+ inches of water per year.
