Original Format: Digital Orientation: Landscape Shot: Plants growing in a rock crevice. Photographer's note: "Rock Mountain has an amazing accumulation of Asplenium species. My best assessment: Asplenium pinnatifidum, Asplenium bradleyi, Asplenium platyneuron, Asplenium montanum, Asplenium ×gravesii, and Asplenium ×trudellii. I found more than twelve plants that I believe are A. ×gravesii on the first trip and now we have counted around 30 plants. Asplenium ×gravesii is supposed to be an incidental sterile hybrid between A. pinnatifidum and A. bradleyi and is usually a single plant growing in a mixed populations of the parents. This presents a problem. Seems the Rock Mountain population of A. ×gravesii has some way to reproduce. These two plants of A. pinnatifidum are very unusual. They seem way different than typical plants of the species. The fronds seem to have an overly acuminate caudate apex. They are very robust, more so that the other A. pinnatifidum plants in the area. I suppose they are just displaying more characteristics of Asplenium rhizophyllum or they possibly represent a hybrid between A. pinnatifidum and A. rhizophyllum. I located two plants of what are possibly A. ×trudellii based on frond morphology and a stipe that is three quarters brown. The stipes of A. pinnatifidum are only brown near the base. Asplenium montanum is quite rare on the mountain, or at least on the southeast side. So far, I've only located two plants. Asplenium bradleyi is more common on the mountain than anywhere else I have seen. Some of the plants are very impressive. Much more work needs to be done on the Asplenium species at this site."
