Please join us Monday, November 6, at 7pm for a presentation by Dr. John Constable, a professor in the Biology Department at Fresno State. The identification of new plant species is commonly associated with exotic locations in far away lands – however, in the San Joaquin Valley a new species of Sunflower was identified hiding in plain site. Winter’s Sunflower (Helianthus winteri), a close relative of the more common annual sunflower (Helianthus annuus), is found in restricted locations in Fresno and Tulare counties. Helianthus winteri favors dry, rocky south-facing slopes and is physiologically active throughout the year. The species exhibits a range of characteristics that similar to H. annuus including photosynthetic characteristics and components of leaf morphology. However, there are also subtle differences in stem structure, anatomy of water conduction tissues, secondary chemistry, and internal microbe composition that may aid the species’ survival in the harsh locations in which it is found and provide opportunities for sunflower crop improvement.
