A low-growing plant with prostrate to decumbent stems and erect, bright red flowers. These are very distinctive with their 5 petals divided into 4-6 narrow lobes. Each petal has 2 small appendages at its base. Leaves are broadly lanceolate to ovate, reducing in size towards the top of the stem. There are records of a related subspecies (subsp. laciniata) in the county although this is more usually found in San Luis Obispo county and south. This subspecies (the right hand photo) has linear to narrowly lanceolate leaves, a narrower calyx and a taller, more open growth habit.
