INFORMATION PROVIDED WITH THE PHOTO
  • date of photo  Jun 8, 2005
  • location   Providence Mountains (San Bernardino County, California, US)
  • family Asteraceae
  • notes   Detail of flowers of Psilostrophe cooperi.

    Individuals of this species had two different overall gestalt types at this time and vicinity. Those that grew on the open gravelly slopes had duller green herbage (more hairy to protect from intense light, heat, evaporation?) and most of the ray florets of their flower heads had become dry and brittle while still remaining attached to the head. In contrast, those that grew in moister, more protected niches (i.e shade of steep-sides canyonettes or surrounded by large shrubs) were much deeper green and their flowers were mostly in full bloom with intensely deep-yellow flowers.

    'Marescense' is the technical botanical term used to refer to flowers in which the dried petals stay attached indefintely, rather than promptly dropping off. Marescent flowers are characteristic of this genus (and some other genera as well, e.g. Baileya), and are what give rise to the common name 'paper-flower' for species of Psilostrophe.
