The specific epithet commemorates Roelof van den Bosch, a nineteenth century botanist who studied filmy ferns
The leaf primordia lose the leaf apical cell early; the marginal meristem initials are atypical in that they divide to produce derivatives in a uniseriate fashion, as in filmy ferns
(Bower, 1889, 1923), rather than dividing to produce segments alternately to the upper and lower sides of the lamina as in other leptosporangiate ferns.
Trichomanes boschianum Sturm, Bristle Fern; Filmy Fern
Hymenophyllum wrightii Bosch is a filmy fern (Hymenophyllaceae) found primarily in Japan and Korea, but with small disjunct populations on the northwest coast of North America.

Elaphoglossum, ferns, filmy ferns, grammitid ferns, lycophytes, Selaginella
Five of the new records belong to Elaphoglossum, four species are filmy ferns, and three are grammitids.

These include the filmy ferns (Hymenophyllaceae), grammitid ferns (Polypodiaceae), and the genus Elaphoglossum (Dryopteridaceae).
Highly abundant groups with numerous epiphytic species in the area are the filmy ferns (Hymenophyllaceae), grammitid ferns (Polypodiaceae), and the genus Elaphoglossum (Dryopteridaceae).

The authors have generally adopted the most recent classification/taxonomy available for a given genus, with only minor exceptions: filmy ferns
are presented in the traditional two genera system, rather than the recently published 9-genus classification by Ebihara et al.
