Andrea B. Posted December 7, 2013 Share Posted December 7, 2013 Blum, A.G. (2013) Phlox hoodii Richardson (Polemoniaceae) Hood's Phlox. Flowers photographed in visible and ultraviolet light. http://www.ultravioletphotography.com/content/index.php?/topic/619-phlox-hoodii-hoods-phlox/ Mesa Verde National Park, Montezuma County, Colorado, USA02 May 2013WildflowerLat [N37°10'07.3"] Lon [W108°29'23.4"] Alt[approx2094m] Synonyms:Carpet PhloxSpiny PhloxComment:On the basis of the hairy calyces and dark green, hairy (somewhat cobwebby) leaves, I believe this to be P. hoodii. Its close cousin P. austromontana typically does not have hairy calyces, and its sparsely hairy leaves are a lighter green. However, there can be a great deal of confusion in differentiating between these two Phlox species and their subspecies both of which are found in Mesa Verde NP. The corolla is moderately UV-reflective as compared to the UV-dark leaves and branches. There is a small UV-black eye in the center at the base of the petals. Reference:1.
