[In a recent paper, "Puerto Rican Fern Notes" (Proc. Biol. Soc. Washington 60: 123-130. 1947), Dr. Maxon recorded among numerous additions to the fern flora some eight species recently collected in Jayuya district by F. H. Sargent, of the U. S. Geological Survey. These include a new species of Elaphoglossum, a new variety of Hymenophyllum elegantulum, and the first West Indian record of Dicranopteris rubiginosa, which Dr. Gleason mentions as abundant but quite possibly is of local occurrence, as it was not found by Mr. Sargent. It was pointed out that the region is one of exceptional interest botanically.-ED.]
