Ceratocephala
orthoceras or Ceratocephala testiculata
(Hornhead)
Family:
Ranunculaceae
(Buttercup)
The achenes of Ceratocephala
orthoceras have a straight beak and the sepals persist as the fruit forms.
The dissected leaves also help with identification. Hornhead is a relatively new
weed on the east slope, currently found mostly along the Front Range. The pictured
plants were found at the Picnic Rock picnic area in Larimer County. C. orthoceras
blooms very early in the spring.
