of the evolution of small homostylous flowers in A.
compared flower ontogenies between distylous and homostylous species in three separate evolutionary lineages of Amsinckia (Boraginaceae) and found that neoteny is primarily responsible for the derivation of highly self-fertilizing species from their outcrossing ancestors.
A similar result was also seen in our studies of the flower development and evolution of homostylous selfing flowers from distylous outcrossing ones within Amsinckia spectabilis (Li & Johnston, unpubl.
preslii), its seed with an oblong rather than a rounded or elliptical posterior, and its homostylous flowers much smaller than 12-15 mm in diam.
albicans Turczaninow, primarily from Brazil, where distylous (a few homostylous collections in Venezuela, Paraguay, Argentina, and a few distylous collections in Mexico, Colombia, Venezuela, Guyana, Bolivia and Paraguay).
Waltheria albicans, when homostylous (see above), and W.
The distylous species typically occur in natural habitats such as chaparral borders, serpentine soils, and Pleistocene sand dunes, whereas many homostylous species of Amsinckia are most abundant as colonizing plants of roadsides, grazed pastures, and agricultural fields.
One or more of the putative homostylous relatives of each distylous species, as hypothesized by Ray and Chisaki (1957a), were also included in the analysis.
Many of the homostylous populations were monomorphic for all surveyed enzymes (Schoen, unpubl.
3) Is homostyly among selfing taxa of Eichhornia homologous or were there multiple transitions from tristylous, outcrossing taxa to homostylous, selfing ones?
Microevolutionary studies of the dissolution of tristyly in Eichhornia suggest that the polymorphism has broken down repeatedly, giving rise to selfing, homostylous species (e.
Based on their intuition and limited cytogenetic evidence, Eckenwalder and Barrett (1986) predicted particular associations between tristylous and homostylous species of Eichhornia: E.
