Synonym: Bahia dissecta. Amauriopsis dissecta. Foothills,
montane. Disturbed
areas, meadows. Summer, fall. Bahia dissecta is fairly common in late summer and early fall growing along roadsides and on dry, gravelly or sandy, open sites in the lower mountains. It has an open, airy growth pattern, grows from 8 to 36 inches tall, and has bright golden/yellow flowers, almost always with rounded, short overlapping ray flowers and a large mound of disk flowers. "Bahia" is for Juan Francisco Bahi, Professor of Botany in Barcelona, Spain in the 19th century. (More biographical information.) "Dissecta", "cut into pieces", refers to the finely cut leaves which occur sparsely along the red/brown stems and more noticeably at the base of the stem. The basal leaves in the picture at left are in their fall maroon.
The genus was named by Lagasca in 1816 from a specimen collected in Chile, probably by Sesse and Mocino on their 1787-1803 Spanish Royal Expedition to New Spain. Augustus Fendler collected the first plants of this species near the Mora River in New Mexico in about 1846. This species was at first named Amauria dissecta by Asa Gray in 1849; in 1889 Britton named it Bahia dissecta and that name was widely accepted for over a century. In 1914 Per Axel Rydberg maintained that the species is not a Bahia and he placed it in a new genus, Amauriopsis, but that designation was not widely accepted. Rydberg's Amauriopsis dissecta name has now been reaffirmed almost a hundred years later as the name of this species. |

Synonym: Bahia dissecta. Amauriopsis dissecta. Foothills,
montane. Disturbed
areas, meadows. Summer, fall. Gently rounded petal tips are slightly notched. Ray flowers overlap and each ray flower is just a bit shorter than the central disk of flowers. The flowers pictured at left are typical of Bahia dissecta; the ones below (more yellow, longer ray flowers, spaces between the ray flowers) are less common and show the wide variety that life forms can take. |
