Edward Willis Graves
(1882 – 1936)

The University of North Carolina Herbarium has catalogued to date 8 specimens collected by Graves, who signed his specimens “E.W. Graves.”  Most were gifts to NCU in 2002 from the Jesup Herbarium of Dartmouth College (HNH).  Six specimens are ferns, two are orchids.  The specimens were collected between 1915 and 1918 from Alabama and Tennessee.


A new hybid Asplenium [excerpts]
by William R. Maxon
American Fern Journal 8(1):  1-3. (1918)

Among the ferns forwarded to the National Museum for identification during the past year are the very interesting specimens forming the subject of this article.  They were collected from sandstone cliffs of Sand Mountain, about two and one-half miles west of Trenton, Georgia, by Mr. E.W. Graves.  The first ones sent in were regarded doubtfully by Mr. Graves as an aberrant form or variety of Asplenium pinnatifidum.  In the light of further field study, however, and from examination of the additional specimens secured, it appears nearly certain that this form is instead a natural hybrid between Asplenium bradleyi and A. pinnatifidum, with which it habitually grows.

At the request of Mr. Graves the hybrid is described below.  It is a pleasure to commemorate in this connection the name of the persistent and discriminating collector.

Asplenium gravesii Maxon, hybr. nov.

Type specimen in the U.S. National Herbarium [US], no.764407, collected on Sand Mountain, about 2 ˝ miles west of Trenton, Georgia, on sandstone cliffs, September, 1917, by Mr. E.W. Graves.  It was found growing singly in the middle of a clump of A. pinnatifidum.

That the hybrid here described has remained so long undetected may be owing partly to the comparative rarity of A. bradleyi and partly to the fact that it and A. pinnatifidum possibly do not often occur in close proximinty, in spite of their nearly coextensive ranges.  Asplenium gravesii is represented in the National Herbarium [US] only by Mr. Graves’ recent specimens.
