This web page is from Mexico and features a number of Salvia images (pages 4 to 12) of some sages of current interest, like S. gracilis, S. curviflora, S. amarissima, and S. fulgens. Note the width of the leaves on the latter. My only gripe is the size of the image. Magnification by 2 x 2 or 3 x 3 would be nice.
