It is probably part of Hohenacker's collection which was published under the name of Aspidium filix-mas collected "In provincia Karabach et in territorio Elizabethopolensi" (hohenacker 1833, ) and FIGURE 2: Silhouette of frond of D. caucasica, X ^; CRFJ2854, Ritsa, Abkhazia, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Pteridological Society.
