Discussion
Papaver californicum grows in central western and southwestern California in the Coast, Transverse, and Peninsular ranges. This is the only caulescent poppy, and the only annual one, native to the flora. In the past it has been included in Papaver sect. Rhoeadium, together with the other annuals that have glabrous capsules and distal leaves not clasping, which are native to Eurasia. Recently, based on differences in filament color, stigmatic disc shape, and capsule dehiscence, J. W. Kadereit (1988b) assigned P. californicum to a new monotypic section and suggested that it originated from the same stock as the perennial, scapose, arctic-alpine poppies (Papaver sect. Meconella).
