From: Pollinator divergence and pollination isolation between hybrids with different floral color and morphology in two sympatric Penstemon species

Figure 5

Experimental design of a hand-pollination experiment. The pollination treatments included intraspecific crosses, interspecific crosses, intermorph or intramorph crosses, and backcrosses among Penstemon gentianoides, P. roseus, and the ‘blue’ and ‘fuchsia’ hybrid flower color morphs. J. F. Ornelas drew the flower image in figure. The figure was drawn and edited in Adobe Illustrator CS6 v16.0.0 (Adobe Systems, Inc.).
