Western Poppy

Papaver californicum A. Gray

Comments

provided by eFloras
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 ).

Papaver californicum

provided by wikipedia EN

Papaver californicum is a species of poppy known by the common names fire poppy and western poppy.

It is endemic to California, where it is found in Central Western California and Southwestern California.[1] It grows in chaparral, oak woodlands, and other habitats, often in places that have recently burned.

Description

Papaver californicum is an annual herb that grows a hairy to hairless stem which may exceed half a meter in height.

The flower atop the mostly naked stem usually has four petals one or two centimeters long that are orange in color with green bases. Petals of the similar wind poppy (Stylomecon heterophylla) have purple bases.[2]

The flowers last only a few days at most. The seeds, once scattered, can lie dormant for years; smoke acts as a trigger for them to germinate.[3]

Taxonomy

Papaver californicum is the only species in the section Papaver sect. Californicum.[4]
