Mansfield, Vt., by Mr. Pringle gave it a place in the flora of the United States, as is shown in the following passage from Mr Pringle's address before the Vermont Botanical Club:

"On this first visit to Mt. Mansfield my work was restricted to the crest of the great mountain. About the cool and shaded cliffs in front of the Summit House were then first brought to my view Aspidium fragrans and Asplenium viride,  for I was still on my fern hunt. The finding of the former added a species to the Vermont catalogue; the latter was an addition to the flora of the United States. Such little discoveries gave joy to the young collector."
