The leaves shown below were collected on 11 March 2014 in support of a hypothesis that a large natural population of over a hundred camphor–scented plants (i.e., putative H. reverchonii var. serpyllifolia) do not exhibit variation of the sort that might be expected of a hybrid.
Details of the collection from the test population plus access to additional images are given on a separate page.
Additionally leaves from other taxa were collected for comparison:
The scale on the images is 1 cm — the same for all images. All are 18% of the original scan at 2400 dpi. Click on an leaf image for a larger view (37%) plus the stem from which the leaves were taken.
